Title: 75 CB400 "Dad's old bike" project
Post by: Pops400 on January 24, 2016, 08:18:30 PM
Started today on tearing down my Dad's old bike.  (Introduction here : http://www.sohc.co.uk/index.php/topic,9471.0.html)

I knew it was a basket case, but in the cold light of day... Holy crap, this is in a bad way.

First step, pull everything to bits, bag everything up and label the leccy on the way, see what is salvageable or saleable. Bugger all budget to do it, so a lot of elbow grease and pulling favours from various people I know will be going on.

Today, took the Girl with me, as she is excited as hell about it. She loved the tea breaks, anyway.  ;D

A quick overview of all the issues...
The beginning[attachimg=1]

All that remains attached of the seat base...[attachimg=2]

To be fair, a few blobs of weld might sort it... on second thoughts, off to the tip with the original seat. Nothing is saving that.[attachimg=3]

Casings are all in a shocking mix of brush paint, pitting and grime. [attachimg=4]

Confirming how long it's been since that day I had to go and recover it after it got nicked. Pushing it up hill all the way home with seized brakes nearly killed me. [attachimg=1]

Downpipes look salvageable. I will probably wrap these in black header wrap to keep costs down. Silencer hasn't faired so well and is toast.[attachimg=2]

Front mudguard is rusty & bent. (You can see that's a bend where it got ridden off with a u lock through the front wheel!) I have sourced a replacement, but may go for a stubby anyway. Not yet fully decided on the front end yet.[attachimg=3][attachimg=4]

Tank needs a real going over, but nothing that can't be saved and given a new lease of life.[attachimg=5]

The clocks look to be off a 350LC, so are going. I have some original clocks sourced, along with a few other bits, in exchange for these, so a decent result. They will clean up fine. I have plans for the new clocks when they arrive. I want to take height out of the front end, but retain some key points of originality.[attachimg=1]

Back at the other end, removed the one shiny bit of the whole machine! So naturally, it came off and will be sold as it doesn't fit with the plan. Looks to have been replaced since the bike left my Dad. [attachimg=2][attachimg=3]

Buoyed by something that came off easy and looked shiny, we had a tea-break.  ;D [attachimg=4][attachimg=5]

The rest of the morning was lost to trying to get the damn bolts out of the indicator brackets to release the rear mudguard. (I say mudguard, I mean sheet of holes and rust...) Gave up in the end and will return with a grinder and a drill to finish that off.

Couple more shots showing the extent of the project. Will keep it updated if any interest the build. Just a gentle start and getting to know it for now.[attachimg=1]

I think with a bit more choke, that might have started!
I'm sure you will make it live to fight another day, there's a great wealth of knowledge on here and I would like to donate something to your project in memory of your Dad.  I have a scruffy side panel or two knocking around.  PM me and I'll fire them off to you.  I'm still collecting odds and ends for my Dads 1953 BSA Golden Flash Plunger.

Nice reg number on it too, I think NCW was Burnley, Lancs or thereabouts, still on the system too and SHOULD be tax exempt from April 2017 providing the date keeps rolling - there's a target to aim for!

As others have said, something of a challenge, but looks a reasonable basis to start with and with the help of your glamorous assistant I'm sure you will get it sorted.
I wouldn't be worrying about originality either given the history of the bike. One more SOHC saved from the scrap heap is good by me.

Great gesture from Orcadian. Just shows the great people we have on here.

Hello Pops (is that what we call you?) and daughter,

Count me in. I have a few bits left over from my 400 rebuild that you're welcome to if/when needed.

I learned loads from the kind souls on this forum that helped me progress and/or saved me a few bob. If I can repay the benefit received through helping your progress, that would be great.

Please keep posting your questions and your photo progress reports.

Best wishes to you both on your project,

D.

Hello Pops (is that what we call you?) and daughter,

You can call me anything you like, as long as it's not late for me tea.  ;D

Pop is fine, I've been called far worse.  ;)

Just finished for the day and got chance to reply and I'm genuinely blown away by the kind words and offers. Not expected and very kind to someone you guys don't even know. Thank you.

Ian / Drew, thanks particularly for the offers, any and all help gratefully received. The plan this far was to strip back to save funds and ditch what isn't necessary, so hoping I won't need too much in the way of replacement bits, but I've no doubt a lot of this bike is missing or past saving, so still formulating a final plan. I will post up what's happening as it happens and what bits I know I need and hopefully some deals will be available. Ian, will PM re the side panels, thank you.

Ash and those who mentioned my helper, yes I'm lucky, she is a petrol head like her old man and loves to help me (so far). She is very much a part of the project and gets my attachment to it completely. I hope when I'm gone, she will keep this in the family.

Currently, my biggest problem is looking like the front end. Forks and yokes may be beyond repair, so considering options there.

I will keep the thread updated regularly.

Instant problem with my cafe racer idea is that Little Miss has now made me promise it will be a two seater so she can come on the back.  :D

Hahaha....smart young Lady........two seater indeed.

Both my Daughters used to be made up if I was home early from work and went to pick them (one or the other) from school on my CX500.......lots of street cred from your Kids from owning a bike.

Nice to see all the offers of help from members of the forum.........not unexpected TBH.......it's one of the reasons why the sohc Forum is so good and why I'm so glad I joined it......I have received some invaluable help from some very kind people.

Keep the photees coming please.

Post by: Pops400 on January 31, 2016, 09:48:14 PM
A frustrating, but quite fun morning on the bike today. Julie, you will be glad to know the girl's overalls arrived during the week.  ;)

Took the girl up this morning to carry on stripping the bike down and the damn rear guard swallowed another hour of time and half a tin of WD40. Rounded and rusted, nothing on this bike wants to come apart easy, so progress is PAINFULLY slow.  >:(

Was just having a chocolate hob-nob break, when my wife turned up with coffee and hot chocolate and her camera. She likes her photography, so told us to just crack on and used the morning to get some practice whilst we set about it. I know the progress isn't exciting or quick, but thought I'd share the pics anyway, to keep the thread and motivation going.

Abandoning the plan to get the mudguard off, set about getting the back end off instead and decided to use the time to teach the girl a bit.

First lesson, how to split a rusty chain!  ::)[attachimg=1]

Then Jess was put on WD40 duty while I got to getting enough rust off to start getting the chain split. Think I may need shares in the damn stuff at this rate.  :-[[attachimg=2][attachurl=3]

Finally split the chain and left it to Jess to knock the link out and get it free. Good girl.  :)[attachimg=4]

Pretty much everything needed the use of the all purpose multi tool (big 'ommer) and copious quantities of WD40 and Bicep... [attachimg=5]

You have no idea how long it took just to get to the point where we could get the b****y wheel out! Pretty much everything sheared, bent or took an hour to coax. Bless me girl, she was patient and calm and got the honour of rolling our prize out. [attachimg=1]

Thank the lord for that. Something moved. [attachimg=2]

Bit of labelling up and tidying from last week whilst the shock mounts soak in WD40. Made the mistake last week of forgetting the masking tape, so had to use gaffer tape to label up and lo and behold, the pen is rubbing off, so took the chance to re-label whilst the girl got the sockets sorted.[attach=1]

Sadly, when I viewed the photos, I realised I am far closer to baldness than I realised. Hey ho...  :'(

Jess was very pleased with her trophies after I loosened the shocks off.

Her "By the power of grayskull" moment (for the 80's kids...)[attachimg=1][attachimg=2]

After that, we had a bit of a breather and a lesson on how brakes work. She's getting there.  8)

Hope to see you there then. 
Fired up my 400 after sorning it for a few months.   Closed the float bowl drain screws,  put fresh juice in,  cranked it over on kill just to get the oil up to the cams.  Turned kill switch to ON.  Fired up first blatt of the starter and it ran like a Swiss watch - only louder and a lot more fun.

Sideways Pictures

Usually caused by smartphones.
If you take pictures on a phone, it automatically rotates them for you (coz its clever) - the forum software isn't clever so if you upload it direct, it will show in the way it was originally taken.

The only option is to upload them to a PC and manually rotate them (as well as reduce the size) before submitting to the forum.

Got a couple of hours in today without my helper, she decided a Princess Party was a better offer.

So I thought I'd take some demolition tools with me and get medieval on that damn rear mudguard to get it out. I can sum the day in one word, to be fair. AAAAAAAAAAAAAAAAAAAAAARRRRRRRRRRRRRRRRRGGGGGGGGGGGGGGGGGGHHHHHHHHHHHHHHHH!!!!!!!!!!!!!!!!!!!!! >:(

I lost 2 hours of my life to 2 bolts. 2 HOURS!!! And I think I have broken a bone in my hand in the process.  >:(

I tried heat, chiselling, tried clearing enough room to shear the bolt. Nothing. Ended up (after missing my target and clouting my hand with a hammer - hence the breakage...) having to drill in stages into the retaining nuts to try and split them. Even that ended up in several broken bits and a lot of swearing. Even after I split them, they were so rusted to the bolts I couldn't just split them off! Never come across anything like it.

Anyway, eventually got the damn things off and I have never felt such a wave of triumph in all my days. The small victories, eh?

I know this will look ridiculous to the serious engineers amongst you, but what an absolute ball-ache this was.

Drilling...

FOR SALE :

One rear mudguard, recently removed. Only reason for selling is surplus to rquirements as I'm going café racer. Showing a few signs of wear, but should buff up fine. Looks like it may have a couple of small pinholes, hard to tell in the light. Serious enquiries only, no time wasters. Open to offers.  ;D

After a victory like that, my hand was bugging me, it was freezing and there was biblical rain, so I consoled myself with really digging around to asses some more of the scale of the project. I had been hoping to salvage the indicators for sale or swap, but they are in a horrible state.  :( To the tip they go methinks.

My real woes are at the front end. Forks and legs are looking beyond repair to me.

I know all this stuff is replaceable, but I never set out to buy a bike 1 piece at a time and just bolt it all together, so it will be a hell of a challenge figuring out what can be saved and how. At least now I can see the rear of the frame clearly, I can start visualising how it will look with the seat and rear.

Last one from me today. Ended the afternoon on a high. I discovered a box of bits that came with the bike, that had got buried in the move. The side panels are in there and look in good nick, other than the brown paint...

But the real bonus is... the missing bit of the muffler was in there, lovingly packed away!  ;D   :-X

Make sure you keep those mounting brackets.
They are a silly price if you want to replace them, they are specific to the 400/4.

No inspiration as such from the show, no CB400's there at all, but the girl got something she really wanted, a patch she chose herself to cover the "babyish" tractor on her overalls, so she was happy.  ;D

She's officially a sohc fan and mechanic.

Ok, so to top all the other problems I have going on, I found out tonight I may be losing my storage in the next couple of weeks.

Normal update service will be resumed after a brief gap once I have found somewhere to re-house. The car may have to go, but the bike is staying. Somehow...

Thanks Aly-B.

Well, came to a bit of a dead stop yesterday after a bit of time off. So much frustration at nothing coming off in one piece and a lot of head scratching, so turned to work on the car to get some thinking time.

Here's where I'm at...

I feel like I can't progress until I can resolve the seat issue, but I'm struggling to find any serious detail on any threads or websites I can find. I see a lot of " and here's my seat hoop fitted" , but no real detail. I'm trying to figure out how this all fits together. I had planned to use the original fittings and possibly the base from the two four seat, but Now I can't see that working for a cafe, as there would be fittings sticking out all over the place. So do I need to decide on a seat first, so I can offer it up and measure for hoops, or are they some sort of standard size? How do folks fit the seats to the hoop bases?

I'm starting to consider a brat seat with a removable hump of some sort, but need to get my head round what the considerations are for mounting, battery tray ideas, welding etc. Even stuff like what brackets can be removed and what needs to stay.

I can find loads of pics of finished bikes, but can't find any to view. Nothing at all at Shepton Mallet and can't find any 400 cafe racers to view, so I'm struggling. Very much the kind of guy who gets stuff more in the flesh than from reading.

I could use some sound advice before I get much further, as I want to have the frame properly finished before I go painting or coating, so I know I'm only going to do it once.

Anyone close enough who wouldn't mind me having a look at something finished?

Also interested in centre stands, or lack of. Most cafes I see in pics seem to have dispensed with them. What are general thoughts? Any other frame things to consider that you guys can help point out?

20 questions I know, but I want to get this right and would genuinely appreciate the input now to get it right first time. Be gentle, It's my first bike build...

Thanks.

Got a couple of hours in today without my helper, she decided a Princess Party was a better offer.

So I thought I'd take some demolition tools with me and get medieval on that damn rear mudguard to get it out. I can sum the day in one word, to be fair. AAAAAAAAAAAAAAAAAAAAAARRRRRRRRRRRRRRRRRGGGGGGGGGGGGGGGGGGHHHHHHHHHHHHHHHH!!!!!!!!!!!!!!!!!!!!! >:(

I lost 2 hours of my life to 2 bolts. 2 HOURS!!! And I think I have broken a bone in my hand in the process.  >:(

I tried heat, chiselling, tried clearing enough room to shear the bolt. Nothing. Ended up (after missing my target and clouting my hand with a hammer - hence the breakage...) having to drill in stages into the retaining nuts to try and split them. Even that ended up in several broken bits and a lot of swearing. Even after I split them, they were so rusted to the bolts I couldn't just split them off! Never come across anything like it.

Anyway, eventually got the damn things off and I have never felt such a wave of triumph in all my days. The small victories, eh?

I know this will look ridiculous to the serious engineers amongst you, but what an absolute ball-ache this was.

Drilling...

The only question I have experience of is about centre stands. Having had bikes without them for various reasons, my advice would be KEEP IT! You cannot imagine the hassle that normal routine checks and servicing is without one, try adjusting and lubing the chain without one, or checking wheel bearings or checking brakes for adjustment or binding. The reason most cafe racers don't have one is a lot of non standard exhausts mean you can't have one, and they often make changing oil filters a right pain.

That's the kind of good sound advice I'm after, thanks.

Zorst will be standard, so no need to dump it for that. Easily persuaded to keep it, I wondered if there was a reason they got taken off, or just aesthetics. My side stand bracket needs welding as it won't take any weight, also, so centre needs to stay for peace of mind.  :D

I fully agree - keep it......a main stand is an absolute Godsend.

I don't know how manufacturers now get away with not fitting a main stand as practically every product sold nowadays has to be 'Safe in use, and fit for purpose'.

Title: Re: 75 CB400 "Dad's old bike" project
Post by: Chris400F on February 25, 2016, 12:00:10 PM
+1 from me too. Removing the main stand just seems like making life difficult when it comes to maintenance.

Re the exhaust, are you intending to try and get hold of a standard system or still thinking of using the header pipes you have to keep the costs down?
Looking back at the early pics you posted the system shown is definitely aftermarket although I can't work out what it is.

Also wondering whether you have had any joy in finding anywhere to store and work on the bike, if you could be losing your current storage.

My Tiger 800 came without a centre stand. It's a £160 option (!)

No problem, I thought, I'll get a rear paddock stand.

£100 and two paddock stands later, wished I'd stumped up for the Triumph kit in the first place.

Thanks all, this is all useful. Any feedback/ suggestions on the seat situation?

£160 for a centre stand, Steve?!  :-X

Chris, thanks for pointing that out, I thought it was a standard system, not aftermarket, so had planned to use the headers and replace the muffler, (to keep costs down as you said). This is where it's a problem not being able to see any for points of reference. How can you tell it's aftermarket?

I have managed to get someone to share the unit and costs, along with the person I was already sharing with, so space is getting tight after this weekend, but at least I can keep the project going and it won't be outside on the patio.  ::)

Thanks for the replies, all. I need to understand as I go along to keep it going. Please keep the advice coming.

The standard collector is 'flat', with the four pipes entering in a line. Yours looks to be 'square', with two pipes above and two below.
Two pipes are welded to the collector and two are held in place by clamps, can't remember whether 1 & 3 or 2 & 4.
The silencer is also separate and clamped to the collector whereas yours is integral.
Motad make an aftermarket replica system which has the same shape pipes and collector with all pipes separate from the collector:
http://www.ebay.co.uk/itm/Honda-CB400-4-Complete-Exhaust-System-/161988706082?hash=item25b7477f22:g:QkQAAOSwzgRWvHXF
Yours could be a Motad system - certainly later ones (there was one on my bike when I got it) had the ends of the downpipes flared and used the standard clamps and collars rather than having integral collars welded to the pipes although I think some earlier ones used the integral collars scheme.

Chris, that's all great info, thanks. I will get some good close up photos at the weekend.

I have a vague recollection of my Dad being very pleased with a micron silencer he put on it back in the early 90s, but confess I haven't even looked at it since I got it. No budget for complete system, so head scratching time now.

Thanks for the link.  8)

Post by: Chris400F on February 25, 2016, 04:23:29 PM
If yours is a Motad system I'm pretty sure this will be stamped on the silencer, on the outward facing side towards the outlet end.

If you are still intending to wrap the pipes then I suppose there is a chance you may be able to find a reasonably priced set of OEM pipes with poor chrome. Rechroming these is expensive so systems that are nice and shiny seem to command higher prices. If I could find a reasonably priced OEM system with good chrome for my own bike I'd have one, otherwise the replica system stays in place.

A few pictures of how I mounted the seat made some brackets one for seat to locate to its a dual purpose one it holds the oil tank too but obviously yours won't .the other two were mounted on bottom of seat .then at back of seat 2 bolts were added to fasten seat to frame .we made two slots in frame so the seat could just sit on frame then slide forward .then fix down with the two bolts .hope the pictures make it easier to understand .it took a lot of head scratching to come up with this way of fixing seat down .but it does work really well .

And the clocks as they were butchered in. No idea why the originals were replaced in the first place, but these look like 350lc clocks to me.

Ace photobombing!

On the topic of wiring I had to make up some leads with suitable connectors for indicators (extend leads for rack mounting) and headlamp (I have a Cibie unit fitted).
If you look on eBay you can buy Japanese 3.9mm Bullet Connectors which worked perfectly for me.
I don't have a crimp tool for non-insulated connectors so soldered the wires then used a regular crimp tool to bend the edges of the connectors to the required shape.
They fit to the standard loom, you can also get double connectors if you need them.

Hi pop. Good to see you're back on track. I know I lost 4 months when the enthusiasm died for different reasons but then you go back and it's the best thing for taking your mind off other shit and focusing on something positive. Every nut cleaned, every weld done (or cut of with a grinder in my case) is a step closer to the end, even when you make a shed load of mistakes as I did, I'm still closer to the end than I was the day before.
On a different matter I've a small grinder free to a good home if you can collect from wolves or Amersham.  The switch is really stiff but other than that is fine.

Bit of progress yesterday, on a day of with the Girl.

Started off by going backwards, putting it all back together again...  :o Decided that I needed some really good clear photos of it side and front on, so I can make a firmer plan of the finished look and dimensions. Still undecided about the seat, so have decided on complete bespoke. Taking these snaps, I will be getting the tracing paper and protractor out and drawing out how I want it. Once I have it done properly, I will know where I'm cutting and what I can lose.

Looks like I can lose a good wedge off the length of the seat / back end, which is good, as I want to stay inside the centre of the wheels front and back, ideally :

Once satiated, back to work...

Everything back off and had the usual struggles of everything being rusted, rounded or both...  >:(

Got half way through getting the front end out, then found that the speedo drive retaining screw is completely, well, screwed!!! Wasn't comfortable getting the drill out on it, so back to that later. Decided to get to work getting the carbs out, so set Jess on WD40 duty, taught her the old "righty tighty..." and she got really stuck in.

What an absolute bar-steward getting the damn things out, though! I think they were as surprised as us when they finally popped, judging by their faces.  ???  ;D

Feeling buoyed that something had come off without disintegrating, (like actual progress was being made!) , Jess scored trophy 2. I let her separate the breather tube and cover from the cylinder head, which she very determinedly did all by herself, despite it being grimed in place tight fast.

Good to see progress, and Jess doing her bit too! Neither of mine (I have one of each) ever really showed any interest in things mechanical.

I thought I remembered, and going back to the first page of this thread confirmed it, that one of the design criteria (as specified by Jess) was a dual seat so she could come along for the ride. Might be a bit cosy to manage that within the centres of the wheels.

With the dual seat idea in mind, yours is an early model with the pillion footrests on the swinging arm. As replacing the frame with an F2 item is probably not really in the spirit of the project is it worth looking at fitting some loops on the frame for pillion footrests as on the later models? I think that would be a lot more comfortable for a passenger.
Title: Re: 75 CB400 "Dad's old bike" project
Post by: Pops400 on October 29, 2016, 09:45:07 PM
Well spotted, Chris. Yes, it was the original intention to have a dual seat, I think I can still manage it if I have a completely flat / brat style seat. I want a hump, though, so at the moment I'm toying with the idea of having 2 seats, interchangeable.

Hadn't considered the rear pegs, to be honest, but that's a fair point. Once I get it stripped back and the frame mocked up, I will look at that and see what solutions I can come up with. I'm immediately thinking something quickly removable, though. I think this bike has to have two guises.  :D

Back on it today after yet more frustrations. Struggled to get the motivation to get started after a wasted trip to Machine Mart for tools, but really glad I did. Had a great day with the girl and made some major progress for a couple of amateurs.  :P

Todays plan was stop  :o ing about tickling it and get the motor out.

I knew I couldn't lift it out with me and the girl, so went with gravity to help me. Laid some boxes down to protect the beautiful casing, finally got out the sump plug that Coco the Clown put in, let it down gently and set to work.

Jess got put on camera duty, so I knew she was well clear!

And she's down!

Ready to pull the motor.

SERIOUS ENGINEERS AVERT YOUR EYES NOW!!! You won't be able to unsee this...  ;)

The vision in my head at this point was that I would just pull the rear retaining bolt, lift the frame back up and voila!

Oh, no... Don't let anyone kid you that this method is that easy...

A lot of wrestling and had to pull the side casing to clear the frame later...

[attachimg=1]

That gave me a bit more wriggle room, so then it was a matter of PULL...

[attachimg=2]

PUSH...!!!

[attachimg=3]

And it's finally out! YEEHAAAW! Cowboy school of engineering!!!  ;D :o 8)
Apologies to the purists, but sometimes you just have to work with what you've got.  ;D

My little helper was as proud as punch. Proper kill for a change. Progress!

So then my little helper got quite a nice little shot of me wheeling the remainder away. (I wasn't going "Vroom vroom", I swear!!!  ;D :-X), so then I parked it long enough to go and take a snap of the absolutely shocking shower of  :-X that is the engine. I have no idea how I'm going to make it presentable. Anyway, by the time I turned round, she was up on the frame and she WAS giving it "Vroom vroom".  ;D ;D ;D

In a fit of perfect timing, my wife arrived with coffee and sausage rolls. So we called a planning meeting.  :)

I know this is probably all inane drivel and childs play stuff to you lot, but I keep writing it up because it gives me a rolling diary of good times with the Girl, blundering about without a clue, thinking about this bike when I was a kid and my Dad had it.  8) Hopefully it will give you all a laugh at our ineptitude and it will give Jess something to look back on when it's her's in years to come.

Anyway, a couple of snaps my wife took of the planning meeting. We actually got through quite a good agenda and came up with some good new ideas.  ;D

Thanks John. It's a right good laugh at times, and sometimes not. Sometimes I think it can't ever possibly be saved and then days like today I think it can. Glad you are enjoying the tomfoolery. It's a bit Heath Robinson, but still. I might rename the thread Cowboy Garage!  ;D

After that, I set about wrestling with getting the rest of it separated and gave Jess her own job, putting the casing, sump and filter back on.

Fair play to the Girl, made me proud, got stuck in after I showed her what to do. Wouldn't accept any help after that. Good girl, she's a grafter. She even had to get on the deck to get to some of the bolts, no bother.

Post by: Pops400 on November 06, 2016, 11:27:51 PM
Anyway, got most of everything else off, but the lack of a 30mm spanner or socket stopped me getting the front end off, so we called it a day, after Jess played bikes with handlebars round the unit.  ;D

I thought she deserved a reward today for working so hard, so I gave her an old cantilever toolbox and a handful of tools and bits and pieces of her own. She promptly labelled it as hers and requested a photograph to commemorate her getting her own spanners.  8)

And that was it for today. I feel like the whole thing has taken a huge leap forward, so feeling a bit more motivated now. It will roll again, this old anchor.  ;D

It has to, we gave it a name today, so it is officially family.  ;)

The easiest way to get engines in and out is to make a little table from MDF the same height as the frame tubes.
To remove the engine...
Make sure the sump and oil filter housing are removed.
Place the table on the right, as close to the frame as possible
Jack up the engine and place two 2 foot lengths of hardwood, about 20mm thick, under the engine.  This allows the engine to clear the lower engine mounts.
Slide the engine out onto the table.
Dead easy, piece of piis.

Nice size workshop you've got there, I'm well jealous.

I'd love to say the workshop is all mine, but I only rent the bit my car is shoved in, I just sneaked the bike out into the open whilst some folk had their stuff out of the way. It's very, very dusty and very cold, so I'm on the lookout for somewhere else, but it's been a Godsend today to be able to walk round freely.

Brilliant account of how you're getting on and something to look back at when you get to ride it.

Just a bit to add to the ad-hoc approach,  a friend of mine always uses a slab of that rigid building insulation instead of cardboard as if you drop something like the engine it won't snap any delicate bits like fins off it.

Also if you need to support the engine at any angle for storing or dismantling then an old car tire let's it sit securely at any angle you need without toppling over.

I've two  kids and don't think you can beat doing anything together really, I remember alot of stuff the same with my father and the fond memories it brings.
You're doing a fine job,  it'll just take time to work through it but well worth it in the end.

As Mike says beware the lower engine bolts as using one too long can result in a hole in the crankcase.
The bolt lengths are given in the Parts List, so that's useful to have.

And I have no doubt that you will have this bike back on the road again - your challenge could be to have it done by 2nd July!

Yep, the insulation sounds a good idea, wish I'd thought of that. I really wouldn't recommend this method at all, though, unless you have a complete knacker, or one that was clearly owned by Coco the Clown at some point, like mine.  :o :-X ;D

Cheers Chris. Good info from you and Mike about the bolts, committed to memory. Will almost certainly be ordering a complete engine bolt kit in the immediate future, these have all seen better days and most all have been hit with the aforementioned Coco's comedy hammer...

I don't think July is feasible, sadly. If time allows, I'm afraid funds won't. Think I'm beginning to accept it as a long term build, sadly. It will be beg steal and borrow of facilities to clean, prep and paint plus parts bin rummaging where possible, so could take a while.

First stop, lots of mocking up before I go cutting and welding, so it's decision time on the front end next.

Just to clarify, it's the engine mounting bolts I was referring to.
The lower left in particular is the one to watch, if the bolt is too long it will go through the casing.
The Parts List seems pretty comprehensive in terms of bolt size and length information.

Yes, I understood Chris,was working on the assumption that mounting bolts would be included in a kit, but thinking about it, I guess they would probably be separate.  :-\

Another job done. Nice one.

Just my two cents on putting it back in as I did my 750 on Friday, I bought two bags of klin dried sand then put a old blanket on top, drop the engine on its side and placed it on top of the sand and abracadabra instant helper. Piece of cake.

Quite a good idea, Steve, but to be honest it was a fair wrestle to get it out, so I don't think I'm going to risk damaging anything. Will probably enlist help on the day and do it upright.

Post by: mike the bike on November 09, 2016, 05:38:54 PM
Upright is a better way.  it means the frame is relatively stable while you carry out the fiddly task of getting the engine in without chipping the paint or breaking fins.

I used some pipe lagging to cover the frame tubes and then installed the rebuilt bottom end into the frame before assembling barrels and head on the bike - makes the engine refit a much lighter job !

An exciting time when things start to go back together and the 'to do list' starts to get shorter !

Managed to get some more time to get the frame stripped today. Frustrating day all round, but did get done.

First of the dumb questions - I assume this is simply a steering lock, but with no keys and not having a bloody clue what I'm doing, how the hell do I get it out? Didn't seem any obvious way and nothing in the manual that I could find. (Not that surprised as it's for security, I guess...)

Post by: mike the bike on November 12, 2016, 10:06:59 PM
The lock is held in by the domed head rivet and the washer.  Try removing the rivet with wire cutters or pincers, save for re use.  Once that's out of the way you need the key to remove the lock.   As you haven't got one then you'll have to drill it out.   Take care not to snap the bit.

Post by: Pops400 on November 12, 2016, 10:09:49 PM
Whilst we pondered how the hell to get the steering lock out, set about the front end removal. Holy cow, the top bolt was a nightmare. Having dropped the lump before trying to loosen it, I found I couldn't get enough leverage on it before the whole frame just moved. Tried everything to hold it, including lying it down and standing on it!  :-X Clearly need to put weight on...

Anyway, quick call to the cavalry and a breaker bar later and finally got it loose. I'm starting to wonder if some of this might be salvageable now though.

Pulled the springs and... er... Milky milky!!!  :-\

Dropped the front out, whilst giving Jess a lecture about not losing the head bearings, so of course having let her carefully get the top lot out into a tin, I slipped and the whole lot dropped and fired the bottom lot all over the workshop!  ::) >:( ;D

Much "fun" was had chasing them round the floor and getting ribbed by the girl... D'oh!

Parked the rest of the front up complete, as it is going to take some jiggery pokery to get it apart, everything rusted in. Moved on to getting the swinging arm out, no huge issues there, but the centre stand turned into a nightmare. Nothing in my manual about removal, am I missing something?!?  ???

Looks to me like a hollow tube, one end flared, but it doesn't want to pull out. I tried putting a socket against the non-flared end and using the gentle persuading stick (FBH) but it only moves a few mm. Is there a trick to this?

This is all I can see to push

and the flared end...

Most people bin the old bearings in favour of taper roller bearings so no worries there. 
Getting that centre stand pivot out brings back memories.   It's been there for decades catching all the road crap and salt ; it isn't going to drop out easily.   
It needs lots of heat,  oil, heat, oil,  persuasion,  more heat, oil.
I sawed the flanged part off and bought a replacement.   Still had to remove the remains of the old one.

It comes with full instructions including how to remove the old lock when you don't have the key, but I don't seem to have kept a copy.
Basically you need to drill the old lock (6mm from memory but may be wrong) then there is a pin you need to hook out to free the mechanism.

Yeah, like the time I was repairing someone's washing machine.  I was tightening up an M8 bolt when the smart alec customer asked what torque I was tightening up to.
I replied (even more smart alec) " I just tighten it till the bolt snaps then back it off half a turn"
Then...the bolt snapped!

Back in the day it was well known all a tea-leaf had to do was to give a sharp left-right tug on the handlebars to break the steering lock and hey presto, your pride and joy has been stolen! I have replaced my steering lock with the one Chris described although I would never use it to secure the bike! I carry a length of ship anchor chain and a 20ft lamppost with me now when out on the bike, can't be careful enough  :)
On a more serious note, I would strongly recommend you get the frame checked for straightness once you have removed the centre stand pivot and completed the welding and before you paint it. You don't want to go to all that effort only to find the frame is bent when it's all completed. My Morini frame was twisted at the headstock by 2 degrees and so was the 400 I'm restoring now. £70 well spent in my opinion.

Righto, well while I have your eyes, I shall ask opinions and advice.

Now getting bogged down with riding position v's aesthetics, v's budget. I'm thinking I can save a lot of the front end now, apart from the tubes, so now I have abandoned the modern front end idea to save funds. That took me straight back to clip on's, but there are so many available I don't really know where to start. Can the quality be that different that I should pay a rake of money, or just buy relatively cheap?

If I go clip on's, I have two concerns.

1. My poor old back... What are they REALLY like to ride?
2. If I go that route, I can't be doing the bar clamps reassembled and just sat there sticking up. So that means a bespoke machined piece, (pricey, so no) or grinding them off here :

[attachimg=1]

So that leaves me to ask :

A. How well will the casting take to being ground down and
B. Will I get lynched for cutting up genuine parts...  :-X

Lastly, clubmans got me all excited at one point, then I decided I prefer the look of clip on's, so is there any reason to look further at them? Any advantages?

And then I had a sudden urge to go dead straight bars. Bluntly, has anyone done this and does it look great or bobbins?  ??? ;D

Many questions, but welcome your input!

Thanks in advance, you helpful lot.  ;)

I'm not into the tech stuff but I have standard English bars on my UK 400/4 and they are quite low anyway. Much lower, you need to be a lot younger and more supple. Would you have rear sets too?. I think straight bars may hit the tank but, I could be wrong.

I like the look of clipons but after riding so many bikes with high bars I now find them way to extreme.
I rode my dads Triumph Trophy last week and was crippled after an hour.

And your only a young whipper snapper Mick. I would have the same crippling feeling if I rode our Thundercat for any real distance. Saying that, the 400/4 makes me ache a bit after about 100 miles and my wrists/ hands are dead after about 10 miles.

Julie, yes I think that rear sets would be a necessity with clip on's, but trying to figure it all out in my head. Can't really mock up without parts, so a bit chicken and egg.

From yours and Mick's comments, I do have my reservations about clip on's, though I like the look. My reservations about actually being able to ride it comfortably are what made me suddenly think about straight bars. Head spinner.  :(

Yes, clipons and rearsets do look good and a million years ago I had plenty of bikes with them on but I was a lot younger, so my body didn't kick up too much of a fuss. It depends if you want comfort or looks I suppose, unfortunately you cant have both. I personally think a 400/4 looks lovely standard.

Post by: Pops400 on November 13, 2016, 09:40:40 PM
I do agree, but there is just no point trying to make this standard, it would cost so much to get it there.

Much thinking and listening to the opinions of those who have done it before to do. Might cut a bit of old tubing to length and mock up some straight bars to test feel. Not sure how to mock up clip on's.  ???

Post by: Chris400F on November 13, 2016, 09:43:54 PM
I had clip-on-type bars on the CB-1 I had and they were too low for me, I ended up fitting adaptors and flat bars.
As Julie says the standard UK bars are pretty straight anyway.
Clubman bars are what quite a few people fitted to various bikes back in the days when the 400 was current - I think you could even have them as an option on things like the Suzuki GT185 and 250 - usually without tank fouling issues or rearsets, so that would be more of a period modification.
I suspect rearsets would probably interfere with the requirement for pillion footrests for Jess.
Also hope that frame damage shown earlier doesn't prove too serious.
Oh, and another +1 from me for keeping up with all these  updates.

Good idea but, it still wont tell you what you really need to know because your static, it's only by riding the bike out on the roads that will give you what you want. I know this from experience, at home here sitting on a CB750 the bike does not feel to heavy for me but I know from experience it's like riding a bloody chieftain tank.

I'm not a fan of clubmans but at least you still have the option to try a few different bars as nothing is ground away.

Chris, yes, I had wondered about the rear sets interfering with the rear pegs, still trying to figure that one out. Maybe I should revisit clubman bars.  ???

Julie, you have me wondering if I have the right bars now. The ones I took off are a million miles off straight or low. I need to find a way to check. When I say straight bars, I do mean literally straight, not even slight angles in there. Wonder if that may be too aggressive / Street fighter though. Not what I am going for at all.

Take your point on mock ups and not knowing until ridden, but hoping I can at least get a feel for pressure on wrists and back. I suffer with my lower back and legs due to the insane amount of miles I do a year, for a lot of years, so should be able to tell pretty quickly if it's a definite no-go. At least I can discount the howlers then and then take time to find out by riding.

All working on the heroic assumption I can get it going, of course.  ;D

Chris, yes I am worried about the frame damage too now.

Frame is looking like quite a problem, but the engine I'm flummoxed by what to do. It did actually turn over and sounded OK, albeit briefly. Semi-tempted to try and clean it up without pulling it apart, but kind of know that's asking for trouble.

Kind of know that pulling it apart is asking for trouble too, though. And probably a load of money I don't have.  :o ::)

Cheers Chris. Still learning.  :-[

Think my preference if it was purely aesthetic will be non adjustable clip on, I like the clean look. Just have to find a way to mock up and see how it feels. Will still try the straight bar mock up as well, out of curiosity. The more I look at Clubman bars, the more I think they aren't quite the clean look I'm going for.

Brilliant thread buddy, great to see the enthusiasm of your lil lass.

My CD had the bolt through bar clamps in the top tree and as I have clip ons I didn't like the holes being there so used the alloy in a tube stuff that you mix like putty to fill then painted the tree after a bit of grinding.

My clip ons are fully adjustable and a pain in the ass (look rubbish and come loose), I'd go for fixed ones once you know if you can get comfy on them

Thanks Alex. If I go clip on's, I've decided they will be fixed if I can manage. I just like the simplicity of them.

When you say you filled those holes with tube mix, are you talking about milliput? Epoxy resin?

Post by: Alex jb on November 14, 2016, 09:36:59 PM
Yep, the alloy putty stuff.
I used it try to make sure it would give the same as the alloy tree, smoothed all the edges where I took off the top material to hopefully avoid any stress risers.

Looks good. I was contemplating shaping the holes, but filling looks good.

The whole build has just taken a massive blow, though. I just got the quotes for welding the frame...

I need to sleep on it, but if I can't find a way around, it could be game over before I've started.

Would it work out cheeper to buy another frame and then cut out the bits you want to splice your frame?

OK, I thought I'd better update where I'm at, I've had a few messages behind the scenes and not been able to answer properly as my head wasnt right on it.

The reality has hit home and there has been a lot of soul searching over the last week and a bit. I stood in the unit surrounded by all this decrepit old crap and a bent, split frame and reality really sank in. This thing has been destroyed by butchery, ravaged by time and bent by bastard thieves. It is in a shocking state and way beyond my talent level. Every single part is corroded to  :-X or broken. It hit me really hard and I had to walk away.

I simply can't afford the repairs to the frame and I won't accept a bodge for the sake of safety, so it is game over for moving on with that. I appreciate all the thoughts on PM about replacing the frame, but I have had to ask myself what is important about the build to me, because it sure as hell isnt value once it is done. This is 100% sentimental and without the original frame, it simply isnt my Dads bike.

So with pure out and out common sense sitting on my shoulder... F :-X it, I'm wet already, I might as well get soaked ;D. Game on!!!

I have decided to park the frame and think about how I get round that and get on with trying to restore what parts I can in the meantime. I have managed to persuade someone to let me use their blasting booth, so will be taking the frame there to get a true appraisal of the damage and get some other bits blasted off. That will keep Jess and I busy whilst I work everything else out and if all else fails, I've learned something and you lot will get some (hopefully) nice shiny parts to buy.

A set back. A big one, but just a set back. As a wise man once said to me, Never give up.

We are back in business, the girl and I.I shall recommence boring you sensless shortly.

Well done Pops, a good decision I reckon. Hopefully you realise just how much help and advice is available on this forum from people who genuinely want to keep, or get, these old girl's on the road for many a reason, be it sentimental, egotistical or just sheer madness. It will all be worth it in the end, even if it's just spending quality time with Jess. There's no rush or time limit, it's been sitting around for a long time so a bit longer won't matter at all. Good luck.

I was in two minds about a replacement frame too after my 400 got nicked,  bent, sidestand bracket broken off.  Is it the same bike or is it like granddad's broom? (three new heads and two new handles).   In essence,  yes, it is the same bike.  Which is why my 1975 bike has an F2 frame and F2 red tank.
It's not exactly like a car where the chassis IS the car.  On a bike the frame is just one component.   Not the legal opinion, just mine.  Go for it.

Finding a frame to cut is not proving easy, Mike. By the time I've looked at the cost plus getting it here, it still stacks up to money I don't have.

It will just have to stay parked until the right donor comes along. In the meantime I am looking through the garage for sale items to raise the cash!

Restorations have a way of sucking the life out of you sometimes and I must admit that the condition of your Dad's bike does look very bad and if there was no sentimental value you'd drop it just like anyone else.
Anyway, what I wanted to say is this, on at least two of the restorations I've done, there was always a problem that I thought at the time was game over or I'd just had it up to the back teeth but somehow, it all came together in the end.
I'm sure the right frame or decision will come along and, in my experience, you'll look back one day and the situation you're in now will seem quite insignificant.
If it was easy everyone would be doing it, but it isn't which is why they're not. I've often had people say to me 'wow, I just don't know how you do it' but the answer is easy. It's not necessarily technical skill that gets the job done but sheer bloody perseverance. For me that's what a restoration is about, the willingness to drag something back to it's former glory when no one else will.
I think the value of your Dad's old bike is not in pound notes but as a platform for you and your Daughter to share something special ie. the memory of your Dad and the life lessons she'll learn from watching you persevere are priceless.

Anyway, pep talk over. Crack on mate. 8)

Looking at your frame, the repairs would seem much easier than getting a different one, The sidestand mount and frame tube is easy to sort. The bent frame tube can be pushed back out easily, the tube dent not so easy but welding on a slide hammer and pulling the dent out as far as possible then a bit of filler will work without weakening the frame.

Pity you're a distance away, I'd do it for a pack of beer.

It would be a good idea to put the forks and wheels back in quickly just to check alignment before doing any frame repairs, once we're happy its good the repairs can be done. Clean everything up and slot just the forks and wheels in, don't need anything else on.

Hello all. It’s been some time and not a happy time.

Unfortunately, I have more than lost faith in this project having lost my Father and then my brother very quickly afterwards.

After a lot of soul searching, I have decided that this is not going to happen for me and is too far gone to save anyway. I don’t want a “triggers broom” and sadly there isn’t enough that I have the capability or money to save. I did get someone willing to do the frame, but sadly they have properly butchered it, so it needs more than I can justify.

I will part out what is potentially useful to people on here, as I had a lot of good advice and friendly help and would like bits to go to genuine enthusiasts, so hope to be able to post some bits for sale on here if that’s ok. Carbs, engine, maybe wheels. Not much else any use I don’t think, possibly indicators if someone wanted to try and save them.

Thank you for the help and interest shown, but my heart has been taken out of this one now.

Best wishes to everyone.

Pop.

Sorry to hear your news. I too often thought what was happening. Your story obviously really touched many of us.

All the very best to you and your little helper!

Sorry for your loss, sad times that I am going through with an old friend too.

And sad about the frame being butchered, I remember I had offered to sort the frame some time ago, I feel bad now that I was unable to do it in time you needed it.

Thank you all

Jess is good and I’m sure will be back to it in future, as will I, but likely with a more complete project that is more viable for us. She has long since outgrown those overalls and a couple more sets, but still helps me tinker with stuff when school workloads allow.

Gutted, but it is what it is and hopefully I can move the parts on to someone who will bring them back to life

Just researching current market prices and will post engine and carbs for sale on here before I offer elsewhere.

Hi Tom

Don’t worry, just wasn’t meant to be on this one. Appreciate your offer anyway. Hope all else is well.

I visited Pops today and purchased some parts including an engine & carbs etc - it was tinged with sadness on hearing about Pops recent double tragedy - he is a really genuine nice bloke who also has a couple of tidy American motors so he will probably be V8 tinkering in the future rather than a tiddly sohc unit.

It's nice that you were able to buy those bits Ted. I'm sure parts of Pop's bike will go on to keep other old Honda 400/4's on the road, which is great.

Hi Ted. It was good to meet you and thanks for the kind words.

I’m really glad that the parts are going to someone who I know will get the best out of them and will help keep another of these cracking little bikes on the road. I’ll confess that it’s not the way I saw the journey playing out, but I never saw the bigger picture coming, so it’s next best result, for it all to go to good homes. That’s why I wanted to sell here rather than eBay.

Really good to meet you, hope it all helps your project.

I think my reality now is to buy a complete bike when the time is right and remember my Dad when I ride it. It won’t be the end of my 400/4 days. Nor Jess’s.

All the best.

Pop

Hi

What a great thread and now pops engine has found a new home

“New heart for the old girl”

Will certainly will do it justice and if you are still about pops400 feel free to chip in on the thread
