We have 2 CB 750 F1's as projects to work on.
I am working old school methods so sure more modern methods are available but prefer to do it my own way
My son has a 1977 which is in parts a previous abandoned project bought as spares not been touched for 25 years. The engine was in the frame as a rolling bike ,with a few boxes of parts and accesories.
We started the rebuild and found we need several key parts ignition - battery - etc sourced these and cleaned rebuild carbs rewired bike as an initial try .
We had the engine running fine ,but stacks more to do.
With 1 bike in progress I saw an unmolested F1 on ebay which also had been of road for 25 years. Bought the bike and brought it home plenty to do but an ideal model for the first project.
Within 2 hours of getting bike we had the engine fired up and running smooth.
The second project was now also running as the lead project with the bike being nearly complete
Removed all the broken trims started to address the front brakes.
Bought new master seal kit braided hoses and new pads
Freed piston Rebuild in Progress
Sourced an original exhaust in fair condition - Fitted and looking good - Old one fitted to project 1
The wheels look like what i had originally on my old bike sure they were called Lesters?
either way they needed further attention.
The front wheel has been hand stripped fine polished and repainted in black with polished rims Pics to follow.
The Headgear /Headlamp and all painted fittings were degreased,cleaned polished and referred back to original standard.
New indicators fitted and working fine
Front mudguard cleaned de rusted - treated - polished - few dings but will do for now Refitted and looks fair
Tank de rusted dried out and awaiting tank sealant to be applied better safe than sorry.
I will try to add pic as we progress with both projects.
here are pics from ebay advert

Presently need new l/h switch unit as the horn pass button is missing and has a oversize screw fitted unless anyone has an old one I could use for parts

Hi Coppertop nice project you have there 8), the wheels are Melber and are Italian I have a pair on my Kettle ;) cheers Mick.

Front end now all sorted and looking good.
Started today on the tank,what looked like a few dings soon showed up all the minor dings as i started prep work.
I decided to strip the tank back to metal and get a clean start.
First i cleaned the inside to remove any rust, with paraffin and grit .Then when dried out and flushed with some fuel treated with a tank sealant.
Cleaned off the underside,treated and zinc primed before 2 coats of red lead were applied.
Then I started on removing paintwork and stripes using course paper to break through surface and scraping with a stanley blade to near the metal surface.
Tank half stripped and looking good.When its stripped i will add some pics as I start repaint job.
Sourced the right colour and it was surprising to me to get the Candy effect you apply silver base and top coat and flat back That will be interesting to try.
-
Was that the exhaust that was on ebay recently, they are like rocking horse poo to find
pete
-
Yes and it was local so the offer could not be missed.
Came in handy as we wanted another complete system for the sons project so he went half with purchase
2 bikes sorted at the cost of 1 original and like you say scarce to find
its in decent nick a couple of dings and a small rust hole near junction bracket under the brake pedal,should be an easy fix and won't be that noticeable
Cheers
keith
-
Sourced a left hand switch unit its coming from Italy - Project 1 sorted with this problem if its as good as it looks, Could not seem to find one available in decent nick in UK
Again this will solve both bikes
Sons project 2 also has issues with left hand switch and some buttons missing so we should be able to build 1 out of the 2 faulty ones
I love this retirement lark plenty of time to mess tinker and do what you enjoy.
(Just hope I will be able to ride them when the time comes)

Seat Base looks rusty and grotty so another strip back to see whats below.
Started today and found the base is very good, just caught it in time before it started to go too far
Cleaned of the brushed paint and rust back to metal I will treat with kill rust and spray back up.
End result should look good before I recover the seat.

Keith Jnr has suggested that we put gel inserts into the foam while we are recovering- Any comments?
Personally I never had an issue with the seats before.
Cheers

Great progress Keith.
I personally wouldn't bother with gel inserts I can ride my K1 all day its like sitting in an armchair compared to most modern bikes.

Rear Seat cowl
The three bolts other side that fasten the trim are rusted solid - Failed to get them out without cutting them off, so I will work around them for now.
The trim fixings that go through the seat crumbled as they were removed - looks like I will have to either source some or make some new ones

Progress
Metal Seat under foam complete
Rear cowl flatted back and primed
The side of the seat you see when its opened up will be my next target today to apply finish coats and lacquer- then when new cover arrives hopefully a completed task
-
Seat base completed
Quick question
The holes in the base unit, I would presume are for drainage of any moisture absorbed by the foam.
The foam looks grotty where the holes are, so I thought of placing some of that black rubber anti slip stuff you put under doormats.This should allow moisture to escape and improve the visual look when you lift the seat.
It would be a shame to replace all the foam just for the parts where the holes are as it is in excellent
condition
a few pics of finished product

Looks good I always thought the holes were to let air escape from under the cover when the foam is compressed when hitting bumps.
Mick
-
That seat base looks real good, i have read somewhere that you have to anneal the metal tabs/spikes so as they dont snap off when re-bending, however i have done a couple of seats without and all was good
pete

The holes are to let the air escape when you sit on it.

Front brake is still sticking
new master cylinder kit
new braided hoses
new piston & seal fitted all movement seems ok
rear retaining arm has free movement on forks
new bolt tension bolt and spring
new pads - pattern could it be they are too thick?
Apply brakes and they don't want to release enough to free spin the wheel
Unless I am missing something ? they should be ok
I have put it down to a senior moment and will have a look later unless there is a something obvious I am missing
-
try the tiny hole in the master cyl, it looks like a blind hole but should be clear
-
Also worth checking the moving pad isn't getting stuck on the excess paint on the moving pad. Often I find removing the paint around the outer edge of the pad with sandpaper, then a tiny smear of copaslip around the outside of it can often help. I assume you didn't have to apply much pressure to get the pad into the caliper housing, as it should almost drop in under it's own wieght.
-
From your list the only thing left is the tiny pressure relief hole at the bottom of the reservoir
-
It was a senior moment
rebled the system and front is working fine
Working on rear of bike and cosmetics now so project 1 is going well
Front end complete
Electrics sorted
Engine nice and smooth fires on the button
Removed the swinging arm to clean and loose the brush paint on frame and surrounding areas
Back calliper freed off and new master cylinder seals ready to fit
Rear wheel stripped ready for detail and repaint
Side panels sprayed rebadged and fitted
Seat recovered and rebuilt
Hopefully in the next few weeks I will be able to post some pics of finished project
Project 2 - Build from Boxes - To become the yellow one
More of a nightmare tying to source parts mainly,without it being an arm and leg
up to date we have had
NOS Front Calliper from Thailand
Switch gear from Italy
Original exhaust from USA
NOS Headlamp bracket from Germany
Side reflectors and mounts from USA
Front forks from UK
and a share in Dave Silvers
Quite a multi national bike
Just hit a problem with the rear calliper its been over drilled in the bleed nipple so it won't close off and of course the pistons are stuck
We will get there eventually, but suppose its not too bad for 7 weeks to date
Retirement is great fun when you have an hobby like these

Completed Tank Paint & Decals today
We could not miss this weather apart from a few midges Keith Jnr did an excellent job of striping/painting/lacquering tanks & Cowls as below
We got the Sulphur yellow match, but struggled with candy antares red from our local paint supplier. Instead I choose from swatchs of candy paints available in rattle cans and picked a BMW Candy paint Silver base and Candy Red/Maroon
I don't think its a bad match - Honda badges are just half in for demo purpose on Pictures removing them now before they mark the soft paint

Mick
Wow paint looks great you must be so proud Keith. Think the rattle can was used as a 'tester' or swatch Mick, although as I said in another post, i've seen a superb Blue/Green 1969 CB750 sandcast done with rattle can's, albeit 1990's formula,
-
Cheers for comments - Can't wait to get them onto the bikes
The lacquer is 2 pack and petrol resistant, (we applied 6 coats) so the finish should be nice and solid.
I didn't know we could get 2 pack in the aerosol,but whole job was done with rattlecans.
The lacquer has the activator inside the can and you trigger the release before shaking and will last usable for up to 20 hrs
-
They look great, nice job
Cheers
Dennis
-
That's an amazing job with rattle cans. Never had any luck with them myself, but that's down to my lack of patience I think.
You don't fancy painting my CB350F do you Keith? Am looking for a painter at the moment.
Cheers Roy.
-
Great job on the tanks, how long did it take you to achieve such a high standard.
Cheers
Tim

Hi Tim
We have always been restoring Bikes and Cars using both rattle cans and Air fed systems
We are not professionals, we just both love to keep going till we get it right.
Not always the case with paint, but we have found if your prep work is good the top coats are easy.
Its also the quality of the rattle cans, we always use a proper paint supplier as we have found the pressure and cast of the spray to be a lot better.
Hi Roy
As we say not professionals, but if your stuck when we have finished these I am sure Keith Jnr would consider helping out.The paint costs for our was around £75.00 per tank
Cheers

Project 1 nearing completion getting ready for final checks/cleans and MOT - every thing seems ok apart from I have had to remove top front braided hose it was too short and binding on left turn
Heres where she was In May 15 not run since 1990's and forgot about

What finish do you have on final prep Keith? I have two CB250 tanks that I need to have painted.I have removed most of the paint with (proper) paint stripper but I was considering dry bead blasting them as final prep with 50/100 Vixosheen glass beads. Will this finish be fine enough for candy (or metallic) paint?

Ash

Hi Ash
We finished with 1200 Wet & Dry prior to primer and between base undercoats
From the read up it sounds as if it would do the job ok,but we are no experts in bead blasting, we did it the old fashioned way with a stanley blade and sore fingers

Bikes look great shame about the blue pipe ;)
Mick
-
Hopefully this will be resolved as we have another original exhaust for project 2 which requires re chroming on downpipes. When they go in so will these
Cheers

i like blue pipes! it shows the bike is being ridden and not kept in a heated garage somewhere.

I'm sure Ralph will pipe up soon now you've said that on a Brit bike yes a Honda no. ;)
Mick
-
There looking sharp Keith. Nice one. I will probably get flamed for this, but I to kinda like blued pipes. Shame they aren't all blued the same though. Guess they aren't double skinned on the F1 then?
Sent from my Nexus 7 using Tapatalk
-
Yes, they ARE double skinned on F1, to go blue like that, one cylinder has been running very hot, for a long time, or the inner skin of the pipe has broken up/cracked or spllit allowing hot gases to discolour the outer skin. If it was running that hot, it could damage the piston (weak mixture), if the inner skin has failed, re-chroming will be a waste of money, as it will discolour again.
-
Exhaust is from another donor bike which has a fine running engine, so I was informed.
I can only presume in its previous exhaust life it had some engine issues, to cause blueing of pipe,also slight yellowing on No 1 pipe.Personally I think the old engine was out of sync and running hot on the 2 effected cylinders causing discolouration.
I think i will still gamble and have them re-chromed again ,but thanks for comments
-
Exhaust on the yellow bike looks like a Motad, in which case pipes would certainly only be single skinned.
-
Just got insurance quotes from Bikesure
2 policies both with named riders so we can ride either - £121 each
Mileage 3k per year
Guaranteed value of 4k +£15
Excellent price I think

Nice bike but would not be happy with that blue pipe ;)

Completed final service and took both bikes for Mot yesterday Project 1 Red - Project 2 Yellow
Both flew through - No advisories ;D ;D ;D
Carbs were playing up on way to test :-[ but with some tinkering both are running fine on 4 cylinders again ;D ;D
Pete the MOT Tester was a mechanic in the 70's who used to build and distribute Hondas so he was a fountain of knowledge with advise on cable routing etc.
Just got the finishing bits to do a bit of paintwork / chrome / polishing and then find some F1 forks for the yellow one

Glad they passed get out and enjoy them ;) I'm thinking of throwing my gold one together now so my dad and I can go out riding this summer.

Been playing to replace a few parts to original
Pics are not from bike library pics
Left mirror on bike is a Tanaka Made in Japan - looks as i remember mine were in 78 with a recess around the stainless backplate

Bought a new original fro DS for right hand side to match and its different same size no recess on rear stainless backplate

Am I wrong in thinking the tanaka mirror is original to the bike?

Mirrors sorted I found an original set off a goldwing

All Sorted and working fine
Next project the seat logo
Previously on the last 1 i did in 1996 I used gold leaf as the old logo was gold.
It would seem that some say white - silver should be the correct colour
If its silver I can use silver leaf but it may tarnish?
Unsure at moment any views ?

Just goes to show how your memory plays tricks on you, I would have sworn that my 1976 CB750F (Red) did not have Honda written on the seat but I have just clambered up into the loft and there it was in gold, and verified by my better half as it was very faded. Here she is in 1976 (the bike not the wife)

Thanks Dennis - Gold it will be
76 Remember it well bought my first CB750 F1 brand new all nice and shiny
Traded n my 400/4 which i had only done 2000 miles on from new for the super bike of the times.
(Everyone else was buying the K6, so it had to be an F1 to be different -I do like the K6 though )
Like you had the I had trusty Belstaff Waxed Jacket
Who needs body amour - it kept you dry.

Happy to help Keith, this is the one I traded in for the F1 the day before I took it in, my trusty old K1, wish I still had it now, I fitted a 900cc conversion and it went pretty well. The white paintwork came about as the tank was damaged so I had to fill and respray it.

A bit more progress made over the winter months
Project 2 The Yellow F1 was playing up so we changed the head and rebuilt at the end of summer. Bike ran fine for 50 miles or so then started to leak oil from fins.
Not a bit but a fair drip rate.
We stripped back down over the weekend thinking it may the a poorly seated seal under the cam tower "pontefract cake" or leaking through the threads of cam tower bolts. We had used standard gasket/thread sealants on all seals, but obviously this was no good in this case.
(http://i252.photobucket.com/albums/hh7/keithjones1400/Honda/IMG_4750_zpskvmz0iok.jpg) (http://s252.photobucket.com/user/keithjones1400/media/Honda/IMG_4750_zpskvmz0iok.jpg.html)
Sure enough when stripped down the seal "Pontefract cake had distorted/beveled and would seem to be the cause of the issue. I would think the seal had moved slightly during first rebuild and obviously you don't know till you run the engine.

Replaced,resealed and rebuilt started up today no oil leaks and sounding sweet.
We also balanced the carbs and whow what a difference it made to responsiveness of engine.

well done coppertop glad you solved it, any excuse andthese bloody bikes leak

Usual 750 problem if leaking around the plug area. I usually seat mine in with ThreeBond (HondaBond). Glad to hear your back on the road and all is sweet.

Hi coppertop, those two bikes are a credit. Seeing them done to the standard you've done almost temps me into not taking a grinder to mine.

Well I do like the mags I have but fancied going back to original spokes.
Fortunately for me Keith Jnr had a full set he wasn't planning on using for now,so he can have mags when I have refurbished the spoked wheels.
Started the strip on the front wheel,thought I may as well go the whole hog.
Cut out all the spokes,cleaned up the rim,which wasn't too bad, mainly surface rust and pitting.
Took the rim for re chroming today £75.00 + Vat (Expected back late March early April - bummer) Prestige plating at Mexborough, South Yorks. Never mind plenty to be going on with.
Removed all the old bearings from hub and started cleanup/Polish.There must be a nack to removing the bearings,I just destroyed one to allow me to drift the other one out - it worked for me.
I am thinking of using Zinc plated spokes with stainless ferrels. Any views?
Are the spokes for the K series the same as the ones for the F1?
Seat now has Honda on the rear, I could not find a decent/correct shade of gold they all were more coppery, who would have thought that a simple colour could be a headache -So I went for Silver,looks well enough and like originals were. template worked fine next to no bleeding. "It is straight its the angle of my dangle when taking pics"

Good way to get bearing out is to use a anchor bolt .have a look on utube .I did mine with one straight out no messing

Cheers - So thats an easier way for future ref.

Usually just put a long bar in the centre that is smaller diameter than the spindle and tap it till the spacer moves sideways and then beat sheeite out of the centre race as you are changing the bearing onyroad
-
He looks a bit dodgy in that vid. Bearing out, now I'm off to do some robbin. ;D

If it wasn't for the accent I would of sworn that was in India or Cuba.

Just been toying with the seat logo Silver or Gold
I decided to try silver which was fine, but still hankering "it should be gold"
I found some gold leaf spray, but obviously too late as I had used stencil.
Nothing to loose and time to spare -so I decided to hand paint over silver.
Gold Colour looks fine and with just a bit of detailing to do around the edges and I should be happy

I just can't seem to get the hang of the pm option I click on it and send but it never shows in my sent box.
I had the same problem, but worked out what it was.
Select 'Profile' from the choices across the top of the page ('Home', 'Forum', ....).
Select 'Modify Profile' then from the list select 'Personal Messaging'.
Near the bottom is option 'Save a copy of each personal message in my sent items by default'. Tick the check box. Select 'Change Profile' (bottom right' to save changes.
That should do it.

Before I start the next part, I thought i should ask for advice before doing it the hard way.
I am looking to change the head bearings as mine are about shot. The existing are original bearings and carriers.
I am thinking of replacing with tapered roller bearings, obviously take all old carriers and bearings out.
The question is:
Do I need any special tools to remove / replace the bearings?
Has anyone come across any problems/issues I should be aware of?
Just seen this on youtube and with the exception of metal on metal looks to have some good tips
https://www.youtube.com/watch?v=3H-G111JXbU
-
The ones you take out will be binned anyway so just beat them out with a long drift and hammer but do it evenly all the way round
-
These are the instructions that came with my bearings, easy enough as long as Bryan says you keep everything level.

Love that final fitting instruction "double check all work".
Don't you always do that?

Does the bottom cup have to fit up to the lip or is there a little gap .?? Hard to see in the picture .when I did mine I couldn't get it to meet the lip so there's a little gap I have wounded if it was ok .it all went together ok .
-
It does look like there is a gap there, if I remember rightly the shoulder that it goes up against isn't square so it looks like there is a gap, but I've never had any bother with it and the bikes been back on the road for quite a few years now. I just tapped in as far as it would go keeping it square.

Head bearings fitted with thanks to all for the info/ links provided
The hackaweek tool for removing the bottom race worked a treat, as did the threaded bar for pressing new bearings in.
Yippee the old girl now steers round corners without all the crunching and stepping out of the steering.
Next project while we wait for the front wheel to come back from re chroming
We found an original exhaust that is practically unmarked and been dry stored - So the old one is for project 2 (Yellow)and the new for my project 1 (Red)
We also have a spare original exhaust that is in need re chroming, we have repaired it and its quite solid so should be ok as a spare should we need one in future years
-
Just fitting the stickers to the F1's from Piki and 1 has me lost as where it is located.
The silver exhaust modification sticker - I didn't have one on the bike, so no reference point to work from.
Advice please if anyone can help out?
-
According to the parts manual I'm pretty sure that it supposed to go on the top of the swinging arm by the rear brake cylinder, mine did not originally have one, but as it came with the kit I stuck it on.

New Exhaust arrived and fitted - Lovely job no marks like a new one.
Checked DS for an original rear wheel rim and its only £20.00 more than having the original re chromed
One on order, no 3 month turn around as I found with the front rim took it in in Jan should be ready to collect End of March
(DS didn't have a front rim in at the time)
-
"Bugger" Ive done it again
Got all the bits to refurbish and fit the new rear wheel
New Stainless spokes from central wheels - New Did Rim from DS - New Bearings from wemoto with retainer - Old Hub Cleaned and polished
All Old bearings out
Made a tool for removing retainer - good job as retainer purchased from wemoto was incorrect size.
Fitted 1 bearing to the hub then the other and that was the mistake forgot to fit the centre spindle -out comes one new bearing to be replaced with another.
New bearing arrived and fitted after the centre spindle this time.
Respoked the old polished hub - cheated and took it to a local shop for spoke trueing and new tyre fitting

Hi Dennis
Thanks - Tyre size is 110x90 x18 Tubeless (but I had a tube fitted)
To think about 40 years ago, I took off the original spoked wheels and standard exhaust, to replace them with a set of Lester mags and a short sportier type exhaust. I just gave these away to dealer when i sold the bike, as many of us would have
Now I just want to try and return it to stock where possible
Cheers

Thanks for the info on the tyre looks great. I know what you mean about messing these bikes up when we first got them, I replaced the original heavy and complicated headlamp bracket with some nicer smaller ones, a Dunstall silencer for a nicer noise and more ground clearance, I fitted an F2 grab rail and indicators because I thought they looked more modern and replaced the steel rear mudguard for a nice shiny home made aluminium one, luckily I kept everything apart from the mudguard which took a while to track down, they looked like they were designed to rust with those open flutes. When the tank started to leak I fitted an F2 tank and seat in black, which I like the look of, the original red items are in the loft though.
Cheers

(Project 2 - 1977 Yellow F1)
After looking for a pair of F1 fork leg base units with no Joy,I decided to try another option
The bike had F2 forks with twin discs and the fork legs/sanctions were fine.
Ash helped me out with a pair of K7 fork bottoms.
Trigger helped me out with F1/K7 brake plate B.
The braided hoses and mudguard off the red project 1 they fitted nicely as a good replacement for now.
The allen studs in the base of the forks are not the easiest to get out but a bit of patience and ingenuity made it happen.
My allen keys did not fit and one was rounded, so I used a screwdriver drill set bit upside down to fit the allen keys.
After a bit of bashing the bit was a tight fit, then a spanner on the hexagon sides they came out easy enough.
Before:

The fork legs transferred over easy, just got to refill with oil ,bleed the brake and then repaint calliper
Another step closer to having 2 F1's looking and running well.

Hi all sorry now working away so updates are slow on progress with project 1 Red completed, it time to further progress Project 2
Yellow project 2 is now underway again as Keith Jnr is aiming for going to TT on it this year
The harness and electrics keep raising issues so we have decided to renew the system and get rid of all the gremlins
New Parts to fit:
Wiring harness - (Thanks Big Al - the harness is spot on and will be a real bonus)
Rectifier - DS
Fusebox - DS
new switchgear left & right for both bikes - classic bikes Germany
Coil Packs - DS
Fuel Lines - Car Store
Original down pipes off to be re-chromed
original silencer to fit on return
I will get some pics if I can as Keith Jnr Progresses
strip down starts this weekend
next stage will be on the wheels to return to spokes - if we can source some hubs?
Cheers
Keith Snr

Thanks Keith, very much looking forward to the updates

All The old wiring Harness removed and you can see why we had a few gremlins

Only issue was new coil packs had male connections same as loom - not a problem female double coupler used
All new fittings replaced with exception of switch gears these are still in transit
Gremlins all gone thanks to the new harness
Quality of work from Big Al is excellent and I would recommend anyone with a butchered Harness to invest in a new one from Him.
-
Looks familiar, I wish I had thought about a new harness at the time, I spent quite a bit of time cleaning every connection with WD40, a cloth, and wooden stirrers liberated from McDonalds, then coated each one with dielectric grease.

I put my loom in dishwasher and hung it up to dry, it came up like new, with years of black muck removed, I could then see the different colours. I just needed to replace some of the outer sheathing and replace a couple of bullets.

We have sourced a set of spoke wheels to refurbish, but unsure if just to save the melber mags or sell them on
The wheels are excellent refurbished condition, they don't take up any room and are getting rarer by the year.
You never know when we have completed the 2nd F1 yellow project we may start another one going.
