CB350/400 / Alloy swing arm, mono shock and different brake disc

« on: September 28, 2013, 07:25:28 PM »

Morning,

I'm s-l-o-w-l-y getting odd bits for a 400/4 special together-so far, a donor bike in bits, twin disc front end, limited ed Yoshi pipe on order (OK, I'm a tart

) and 2-4 seat.

I've seen a few really nice specials based on taking a 70's bike and fitting modern running gear, which I think would make a nice contrast to my mainly stock 4.

So, does anyone know of an alloy swing arm that would be an easy fit? And has anyone ever tried making a 400/4 monoshock?

For my stock bike, are there any brake discs that fit straight in and give better performance? I'm thinking holes, slots etc. The system is pretty much all new, braided hoses etc so I think I've gone as far as I can with it.

CB350/400 / Some info on Yoshimura pipes, included the limited edition one

« on: July 05, 2013, 12:28:48 PM »

For those of you unaware, Yoshi are doing a limited edition hand bent pipe for the 400/4. I wanted one, so managed to get the supplier details and prices for the UK. Thought you might be interested.

Supplier is Performance Parts in Daventry, 01327 706139.

The Normal Yoshi pipe is:
110-441-4640 : JMCA Machine Bent CB400 FOUR >> £650 inc. VAT. Available to order from Japan – lead times 3-4 weeks. http://shop.yoshimura-jp.com/en/product/syousai.php?id=410
Obviously this can be ordered any time.

The Limited edition Yoshi pipe is:

150-441-0840 : Hand Bent CB400FOUR 74-77 >> £799 inc. VAT. Availability – see below.

150-441-0840 is limited edition system and orders will only be taken until 15th July, 2013. It includes both the R & S baffles.
The factory currently has a large number of backorders for this product. Numbers that can be produced are also limited since this model is hand-made. Based on the current orders, expected time of completion is approximately end of October.
We appreciate that this is quite a long time to wait, but this is definitely a very good opportunity to have this limited product.

I've just ordered the limited one. Anyone want to buy my spare 400/4 project? I'm Broke!

CB350/400 / Gasket set from David Silvers, lack of O rings

« on: June 21, 2013, 12:37:42 AM »

Has anyone used this? http://www.davidsilverspares.co.uk/CB400F-SUPER-SPORT-FOUR/part_28474/

The one I got has no O rings that fit the oil pump-neither the dowels, the pump chambers or the spigot that goes in the cases. It does have a bag of about 3 different sizes, which appear to have been thrown in at random. I've emailed to complain, but thought I'd see if anyone else has this problem.

CB350/400 / CB400 chokes

« on: June 13, 2013, 09:47:57 AM »

I've got the carbs off as part of a strip down to replace the chains. I can't help thinking that those choke butterflies must be restricting the bike a bit. Has anyone tried removing them and fitting a different choke? Most mikuni carbs I've seen have an extra hole that is opened up, do the keihins have something szimilar blanked off?

CB350/400 / 400f primary drive chain

« on: April 29, 2013, 10:39:48 AM »

Morning,

What is the mile limit for the primary chain? I'm sure it's 40K. Mine is up to 43K and making big clattery noises...

I'm thinking of stripping the engine and doing new chains, new rings, regrind valves, valve stem seals, gearbox bearing and replace any other seals I see. Can anyone think of owt else worth doing? Camchain adjuster should be OK, it was tackled a few years ago.
Finally, you can't get primary guide rubbers. Is it recommended to shim them up a bit if they're worn? Be nice to shut the rattles up, at least for a mile or two.

New Member Introductions / CB400f sufferer in Derbyshire

« on: March 03, 2009, 08:09:34 PM »

I have a high maintenance lady. She requires expensive, shiny items, and often causes me great frustration. Then makes it all worth it by being immense fun. She is a 1976 CB400/four, in blue. Bought of a bloke in London who lavished great care on her, I got her as my first big bike after passing my test.
I also have a CG125, and two BSA bantams, one of which I'm restoring as a mini cafe racer. I live near Matlock in Derbyshire. Ayup all.
Oh, forgot to say-I'm also on the classicbikeforum site, same name. I'll post a link to here, for fellow SOHC4 sufferers Smiley

CB350/400 / CB400f camchain and primary drive conversions?

« on: March 03, 2009, 08:05:57 PM »

(posted this on the .net site, sorry if you've seen it)

One day, I would like to rip apart my 400's engine and fit brand new absolutely everything, so I can be sure (!) of reliability. The two main gremlins are the crap camchain adjuster (new chain, adjusters etc fitted october) and rattly primary drive. It sounds like there is a little man playing maracas under the fuel tank, and apparently this is normal! All I need is steel drums in the carbs and dancing girls on the clocks. I've heard vague mentions of a better tensioner and belt drive available. Where can I get these, and does anyone have any experience of these? Preferably from sources in England, since shipping things from America or Japan would be rather expensive.
