Default 1998 AC454 valve clearance??

Anybody know the valve clearance for a 1998 454 4x4? I have to do the valves on my uncle's bike sometime, and the manual doesn't show what the valve clearance is. Just says "dealer maintenance" by valves.

Default 1998 AC454 valve clearance??

Andy My 2002 shop manual says (cold engine) intake 0.05-0.10 mm (0.002-0.004 in.)
exhaust 0.17-0.22mm (0.007-0.009 in.)
It just reads 500cc and does not give a year they should all be the same anyway

I hope this helps.

It is the same. I checked my shop manual for my '98 454.

sweet! thanks a lot on that. I figure after I go through the carb, drain out the fuel tank (water leaking through the weak a$$ gas guage- which will be replaced), replace the battery, and possibly install a new float kit, I might as well adjust the valves. Never has been done and this thing has about 1800 miles on it now.
