Timing chain tension
I installed the Sparks big bore kit and Sparks did the porting, cams and valves. My question is on the Sparks manual timing chain tensioner. How tight should it be set? If I turn it in just til it touches it seams to loose.
Re: Timing chain tension
On the mechanicals, I like to go as far in as I can turn it with my fingers (until I can't turn it with fingers anymore) then a half to 3/4 turn more past that point. After adjusting, rotate the primary counter clockwise a couple of revolutions and make sure the chain is sitting good on the sprockets and not too sloppy.
