Winter Work

[hondatri]

 Had a rethink after discussing with local motorcycle shop a very experienced man who used prepare racing engines. Ths spacer was fitted to alleviate end float of camshaft, So into workshop
(shed) Heat on and replaced spacer reset timing and valve clearances. Now for carb overhaul Is there any info available on overhaul of the Keihin Carbs.

Hi,
     A bit of a weird one,have checked different parts drawings, but cannot find it in 350-400/4 parts catalogs, except early cam-wheels appear to be solid, so maybe it was a part of the cam-chain wheel pre 1975?

Forgive me if I am sounding thick how the hell does that stop camshaft end float someone explain?

It is too rusty to be any kind of end float.

I'm sure it will be fine without. The strange thing is, I've stripped 3 of these engines in the past two years and they all had this part. One was a 1976 bike. Not sure of the others. I think they just get left out.

Hi Bitsa,
              agree with you 100%, no loose cam-wheel screws found on mine despite high revs and heavy handed throttle, will Lynx's bit be the new must have item worth tens of pounds on fleabay.

I have only come across 2 of those in all my years and both were the 1976 engines.
