All I want to do is check my valve clearances, should be simple- right?
Bike was running fine most of last season, but poor starting made me decide to take a look at the valves before timing and carbs...
Issue one; when the end of my camshaft is at the position stipulated in my Clymer manual, it states that I should be able to check exhaust valve clearances on cylinders 1 and 3 ; except the lobes on #3 do not align with those on #1.
Is there some other secret manual I should really be taking reference from ?
Issue two ; the smallest feeler guage in my kit is .038mm, and none of my valves has that small of a clearance, even though the minimum tolerance is meant to be .06mm.
I'm stumped; has my 1982 DOHC been substituted with some other engine?
