A couple of "tune up" questions...
Mikep328:
I want to verify that the correct tappet clearance is, indeed, .005mm/.002" as shown in the shop manual. I have never seen a tappet clearance that small and want to verify folks experienced with these engines that it is not a typo!
Re gauge- synching the carbs: Page 6 of the shop manual states that to adjust synchronization, first turn the throttle stop screw so that the clearance between the throttle lever and stay is 56mm. Is that normally done or is sync more often performed at idle or some other specific RPM?
The bike is running great overall and idles nicely at 1200 RPM but there is some roughness at constant slight throttle opening, as in slow town traffic where the throttle is at maybe 1500-1800 in low gear. This was very apparent/annoying in Bristol yesterday. >:( It also still does not take opening the throttle quickly as well as I think it should. I figure the mixture screws need more attention and/or my bench sync was not as good as I thought it was. ::)
Trigger:
Tappet clearance is 0.05mm on the 400.
I don't know too much about the set up on a 400 but, a expert will be along soon

'Ere Trig, did you miss out a zero in your reply???
Trigger:
Nope, Mike has an extra zero ;)
Trigger:
Just looked it up or 0.002in if you are old school
