who would sell a brand new idler gear with two sprockets? No such thing from AN. I am unable to take the slack out of the cam chain on my Atlas. At the slackest it measures 3/8". at the tightest it measures 1/16". Cannot do any better than that. New chain. I am guessing it is sprocket wear, everything else is appears good. AN sells the cam sprocket. I could remove the head to unload the valve springs. I wanted to install a new heavy duty Iwis cam chain, discovered the old one was smacking the tensioner bolt. The motor does run very well, though.
