getting the carbs in took some pushing and loads of lube once they where mostly in i pushed the airbox in as best i could then just got the jack handle in the airbox gaps which look made for this task and gave em a good shove, popped in eventually then done up the jubilee clips.
Anyone know of a possible timing mod
Reason being I decided to balance my carbs, thought it best to check valve clearance first
They were spot on.
When I turned the engine for #1 tdc noticed my exhaust cam was not aligned with the cam mark but was in the
One o'clock position
My engine sounds right runs good and valve clearances correct so decided not to worry about it
But it's bugging me so the only conclusion I can think of is that the previous owner had intentionally set it like this as a power mod ?
regards the cams being out - maybe they just settled for it as it was, I don't know if it would be a mod....but durations of open/close will affect running..
As many said on my pictures I was a sprocket out, it took a long time to figure out how to take up the slack with a sprocket and small clockwise turn - have done it 2 times now as I had to do valve clearances...
If its working fine then you may be best to leave it - but if you a like me then you might not be able to resist
Put some marks on it now so u can see which chain link matches with which sprocket tooth
I did not do that and it has taken me ages - but the 2nd time was quicker as they gave me a good guide to where I needed to be

No power mod, it is a tooth out.
I have seen it before where the owner thought it was close enough, he did not realise it was a tooth out. Engine were running fine before and when we fixed it he did not notice any difference.
Before I changed my cam chain it was over a tooth out because the chain had stretched so much, it was running fine except for the rattle and to be honest I did not notice any difference either.
Ok thought it might be a clever timing/extra power mod but if nobody else has heard of it
Then I'm definitely gonna reset it to correct timing as I can't accept it not being incorrect
Takes a few turns to start from cold hence the valve clearance and carb balance check
Hopefully this will solve the cold start riddle as runs perfect when up to temp
The trick to setting cams is keeping all of the cam chain slack toward the back of the engine and counting the chain pins between the two timing marks..... Easy
