CB350/400 / Re: Hubs & fork legs
« on: June 20, 2016, 02:27:35 PM »
Hi Ash,
Excuse my ignorance but how do I navigate to your VJMC  CB750 lower fork leg refurb article? I cannot seem to navigate to it via the site.
I'm just about to go into the man cave now with a huge mug of splosh and digestives to assemble the newly blasted lower fork legs.

CB350/400 / Re: Hole in bottom crankcase
« on: June 20, 2016, 02:23:31 PM »
This is how my 400 engine rebuild journey started!  When I was 17 I traded in my CB200 for a s/h 400/4 from D&H Motorcycles in Acton.
It was a great bike, a red F model. It was previously owned by an older gent who had fitted a huge barn door fairing, massive top box and suitcase sized panniers complete with front and rear crashbars. I removed all of it within a couple of days including the front crashbar.
I replaced the bolt and went for a ride, when I arrived home the engine was smothered in oil.  The crashbar mounting bolt had replaced the original lower engine mounting bolt and was slightly longer to take into account the 3mm crashbar mounting lug. it was too long and split the lower engine case when I replaced it although I didn't notice at the time.
I tried the epoxy glue, liquid metal, chewing gum, body filler method and nothing worked.  I ended up buying a s/h engine from Frank in Ealing when he used to break bikes in a garden shed!
6 months and many miles later I took the engine apart to replace the cam chain on the dinning room table (the tin of linklife chain lube was boiling up on the gas stove and the cylinder head replaced the leg of lamb in the oven at the same time).

I have rebuilt four 400 engines over the years and they have all had the same issue as yours does.  As I normally have the engines apart for a rebuild I use a fine file to clean up where the aluminium casting has been turned over by the flapping cam chain.
I've never had a problem with any engines following the rebuild and file surgery although I always install a new cam chain, both tensioner blades and the sprung tensioner horseshoe making sure the tensioner plunger has no markings caused by previous owners over-tightening the tension adjuster.

Thanks for the advice, all now on order  :).  Obtaining the correct coils with a 4-ohm resistance is proving very, very difficult though!

I fitted a Boyer to my 400/4 in 1992, its still in there going strong and I have never had to do anything to it once it was set. Ill be fitting another one to my project 400/4 no question.

CB350/400 / Black NGK plug caps
« on: June 07, 2016, 10:33:50 PM »
I'm having to replace the coils and plug caps on the 400/4 project as the old ones are past it being cracked and broken.

DSS has the correct? black plug caps for cylinders 2&3 but not 1&4.  The price seems a bit on the expensive side though and I can only get two but need all four so I'm looking at buying a full set of black NGK's from e-bay at a third of the price. 

Can anyone advise of the correct NGK plug cap ordering codes, there appears to be so many all with slightly different angles?Does anyone know if I can get the coils cheaper on e-bay, DSS are charging 29.95+vat+p&p per coil?

I'll post a few pics of the rebuild so far in the next few days, the engine is now complete and ready to fit into the frame and the marathon carb re-build is finally over but they are not yet tested for leaks although all the jets, needles, gaskets and o-rings have been changed throughout including the link tubes and I live in hope  :-\

Other Bikes / Re: Endoscope, which one to buy?
« on: June 07, 2016, 09:48:09 PM »
Thanks for the info Chris.
I think this is a case of Sod's Law in action!  I bought an endoscope last Thursday on Amazon, I go into Lidl and Aldi every week to check out their deals!!!!  The one I bought cost 65 pounds and is made by Teslong with a lithium battery, 3 meg camera, snapshot and record onto a supplied memory card.  It had good reviews (5 star) so I just thought I'd buy it with my Christmas vouchers  :).  It appears to be pretty good although not used in anger yet, that will be next week when I look down the bores on my Jota (Honda Jota  ::) ............).
I'll give some feedback next week just in case anyone else is thinking of buying one.

Thanks for the advice so far. Roy, if you can let me know the make of your one that would be good.
I have an Aldi near me, I'll see if they have anything.

Other Bikes / Endoscope, which one to buy?
« on: May 27, 2016, 01:03:01 PM »
Hi there all,
Does anyone here have any experience of buying and using an endoscope on their bikes?  I'm looking to buy one with the Amazon vouchers I got for Crimbo. There appears to be an amazing array of these for sale with very few having reviews!
I need to get one with a small enough camera to go down a spark plug hole to look into the combustion chamber etc so the led lamps would need to be good. Picture and video recording would be ideal. If anyone has used one and can recommend a model this would be good.

CB350/400 / Re: Wasn't as nice as the photos in the flesh
« on: April 25, 2016, 02:59:09 PM »
It's still nice though. I agree with you Ash, the 400/4 is undervalued. Prices seem to be stagnant compared to Dukes  :o. At least being low in price more folks will want to ride them and not sit looking at their 'investment'.

Welcome to the forum.
I started in 1978 on a 1966 CB160. I graduated up to a CB400/4 in 1980 and have had one ever since  :).
Good luck with the CB750.

CB350/400 / Small items wanted
« on: April 25, 2016, 12:54:00 PM »
Hello all,

The multiple boxes of bits bought as a 'project' 400/4 are slowly coming together to form a motorcycle  :D.

Whilst every box is giving up its treasures I am finding the 10% missing items are really hard to obtain!

I am looking for the following items and hope someone here may have them for sale......

3 black plastic carb idle screws covers.  These are the small plastic 'covers' that fit over the brass idle screws on the side of each carb. I have one, I need another three. I thought these come as part of the carb rebuild kit, they don't, ho hum :(

The black plastic 'bung' that fits in the knuckle of the kickstart. It covers the open end of the knuckle where it fits over the kickstart shaft, part number is 28305-333-010, it is now unobtainable and they don't even turn up on the Antiques Roadshow anymore ::).

If you have any of the above for sale please let me know.

Dave
