CB350/400 / Engine rebuild questions
« on: January 18, 2018, 06:14:03 PM »
Oh dear oh dear Julie, what have you started!

My wife is convinced I’ve got an internet girlfriend as all she hears is my god Julie is fantastic, she snatches the iPad and sees pictures of engine bits. I then get accused of closing what ever I had been looking at previously! Oh well.

Anyway you have given me the confidence to persue the camchain tensioner suspicions. So far I have the head and barrels off and getting stuck into the cleaning. All this is leading to the first of many questions for the experts.

First up. The circlip  that retains the tacho drive. How do I remove it?

Second. Cleaning carbon off exhaust valves. Have tried soaking in diesel for a few days. It’s still solid and reluctant to go to physical with it. Also cleaning up the piston which is a much softer metal, advice please.

Also may I must add my thanks and admiration for a really good thread and finish you have achieved. I now understand why you moved from Kent to be very near Trigger.  ;D

Recommended Sources for Parts and Services / Acid dipping service
« on: January 05, 2018, 12:37:27 PM »
Does anyone know who does acid dipping for engines cases? Ideally in the West Midlands. Also what strength acid should be specified to remove the oil?

Thanks, Greg

While at work for the next few days I am planning the engine work list. Subject to any problems that I find what extra maintenance would you do? I guess a light grind of the valves would be worth doing, the cold pressure was 165-175 when I checked in the spring. I would also like to give the case and fins a good spruce up, is soda blasting worth doing or just scotch bright and polish sufficient. As I'm not doing a full restoration, some sort of patena is fine. Also what do I need to pay attention to when looking for maintenance issues. As this is my first time into the inner workings all dumb and obvious hints would would also be apreciated.

Tools wise I have the Honda and Haynes manuals, a precision torque wrench, standard sockets and spanners. Thanks in advance, I'm sure there will be follow up questions.

CB350/400 / Stuck Tachometer cable
« on: July 21, 2016, 06:34:27 PM »
Hi all,

I have a noisy cam chain so need to take the engine out. The tacho cable is prooving reluctant to leave its current location. I have removed the screw in the engine but can not remove the cable, I have tried some heat from a hot air gun and have left it covered in WD40. If this fails and I disconnect the tacho from the instrument and then remove the engine followed by the cover, is there any risk of damage to the drive? Failing that any other hints.

Thanks for all advice.

Humour / A mans best friend
« on: October 12, 2015, 11:03:44 PM »
On our local radio station today they were discussing if a dog could really be a mans best friend and invited callers for their view. Well this guy calls in to say that his dog has been everywhere with him and was currently sitting by him in his van, as he had been doing for the last 14 years. He then went on to say that he had said to his wife that the dog was his best mate. Now his wife said that she should be his best mate not the dog. Well, his response was as follows. " If I locked you both in the back of the van for a few hours who would be the most pleased to see me, well?"

Nearly lost my mouthful.

CB350/400 / Fuel bowl gasket
« on: August 30, 2015, 02:12:28 PM »
Hi all on a wet afternoon. Ideal for putting a carb back together.

I brought a repair kit from Cruzinimage of eBay fame, all going well until the fuel bowl gasket. It seems to be over size for the groove that exists. I can just about squeeze it all in but a bit usually pops out. Have any of you had a similar experience? Did you use some sort of glue to hold it in place? If so what?

Thanks,
Greg

CB350/400 / Seat pan
« on: August 07, 2015, 07:47:36 AM »
As my seat has a split I have stripped it down and to treat the rust, however I have found a couple of cracks. Do you you guys just weld them up or should I add some reinforcing strips across them?

While I'm here I've been looking at some Carb Refurb kits. Starting with DSS at £20 each or on eBay a kit of 4 for just under £30 from Japan. Is price just the difference?

Also on eBay an exhaust, original headers and collector if your interested. http://www.ebay.co.uk/itm/Honda-CB400-Four-genuine-OE-exhaust-system/391215284022?_trksid=p2047675.c100009.m1982&_trkparms=aid%3D222007%26algo%3DSIC.MBE%26ao%3D1%26asc%3D29975%26meid%3D713b278e83764ac79d58c3bc5325ed69%26pid%3D100009%26rk%3D4%26rkt%3D10%26sd%3D252042377563

CB350/400 / Spark plug cross threaded
« on: July 19, 2015, 07:31:29 AM »
Very frustrating as I have just got the bike to MOT status, however had a starting problem so have taken the plugs out. Now I was aware that No. 4 was tricky to replace as the initial damage had been done by a previous owner. Now I can't get the plug back in and more than a half to one turn, so it looks like I've lost the original thread. Are there any suggestions or is it going to be a head off and an insert fix. Suggestions from the wise please.

Thanks
Greg

Humour / Hot hatches and super models
« on: June 19, 2015, 01:37:00 PM »
After a small event on an orange coloured aeroplane I found this on another forum.

It seems to me that Hot Hatches and supermodels have many things in common after all...

They are high maintenance to keep in prime condition
They are built for speed not comfort
Body filler is required to hide the signs of aging
They perform best on high octane fuels
They can be very temperamental when out of tune
There is always a later model to try to keep up with
Things tend to backfire when they get coked up
Best performances are usually acclaimed when stripped down to the bare minimum

Hope this brings a smile to your day.

CB350/400 / Which CB400 do I have?
« on: November 09, 2014, 06:26:48 PM »
I brought my CB400 from a dealer who buys bikes across Europe before shipping them to Japan this one he felt was to good so sold it on eBay. It was originally registered in Holland and has the following serial number CB400F 1069572. I ask this question as I ordered some bolts from DSS using a CB400F manual. DSS shipped the parts I ordered however on inspection of the originals I find they are 1mm to big. The bolts in question being for the top clamp for the front forks. The originals are 7x54 flanged with flanged head cap in chrome, the parts I ordered are 8x56 with separate washers all in chrome. So what have I got?

Edit. Just to add it was first registered in Nov 76. Thanks, Greg.

CB350/400 / Front fork problem
« on: October 22, 2014, 11:04:59 PM »
I am replacing the seals on the front forks. The first one has come apart fine however ( there is always a however) the second is sulking. The bottom socket bolt, oil lock piece and under seat pipe are all rotating! So how do I hold the internal gubbins still while I undo the socket bolt. Thanks in advance for your wise words.

CB350/400 / Oil pan/sump torque setting
« on: September 01, 2014, 04:08:12 PM »
Just spent a couple of happy hours cleaning the sump and changing the filter. Now all is back together I can't find a torque setting for the sump bolts. Can anyone let me know?

Thanks,
Greg

CB350/400 / Breather chamber and air box
« on: July 31, 2014, 05:10:52 PM »
The bike I have was partially dismantled before the owner sadly passed on to the Ace Cafe in the sky. The breather chamber that goes under the air box has not been refitted. So can it be reattached in situ, if so how? Or should I dismantle the air box, attach the breather chamber and put it all back where it started from. I only ask hoping there is a short cut. Thanks for all advice.

CB350/400 / Liquid sealant and filter question
« on: July 03, 2014, 07:56:02 PM »
Advice from the wise please.

First up I was wondering what "liquid sealant" I should use when replacing the socket bolt at the base of the front forks?

Secondly, I am missing the filter from the base of the air box that goes between the two panches. DSS does not have any so was wondering what material to use and then trim to fit. Suggestions please.

Cheers Greg

CB350/400 / Exhaust split collars
« on: June 14, 2014, 08:06:05 PM »
Hi guys.

I am about to get my first 400 next week. Now it needs a new exhaust system as the collector box is shot and it has an odd silencer and poor chrome on the down pipes. So I was intending to put a full replacement in from the Silver guys. Now my question is should the split collars be replaced as well or are they subject to condition? I will post pictures once I get the bike but it's a very low mileage model from Holland so need to get an MOT before I can register it. Thanks.
