Hello,
I've had the bike for a while, then today had occasion to remove my cam cover. Present clearances are....
LEFT IN        .010 (0.25mm) CORRECT
LEFT OUT    .011 (0.275mm) TAD LOOSE
MIDDLE IN    .008 (0.20mm) CORRECT
MIDDLE OUT .010 (0.25mm) CORRECT
RIGHT IN      a tight .008 (0.20mm) TAD TIGHT
RIGHT OUT  .012 (0.30mm) TOO LOOSE?
So not a million miles out but is it worth refining the odd ones that are not strictly by the book?
Thanks
 
I use 8 thou inlet and 10 thou exhaust, so not all yours are right (by my way of doing it).
 
Thanks Grant.
Although not spot on, are mine really worth adjusting such a small amount?
P.S. thanks for the recent other advice by-the-way - there have been developments and I'll keep you informed. Cheers
 
You will disappear up your own exhaust pipe chasing perfect clearances.
Run it like that for a few hundred miles (better a bit slack than a bit tight) and re-check to see if they are moving at all.
