Hey MO! I just installed the big bore kit and performance camshaft, but I don’t know how to time the cam to the crank!- desparate in Detroit
I have been getting a few inquiries on timing marks and cam timing. The first picture shows the flywheel in the Top Dead Center position. Do not confuse the 2 marks. The F mark is the mark for when the magnetic pick-up fires the CDI. The T mark is for when the piston is at the top of it’s travel. The T mark must be aligned with the alignment mark in the case. The next picture shows the correct position of the cam for Top Dead Center.
When installing the chain on the cam make sure that the chain slack is on top of the chain and the bottom of the chain is tight. After you install the chain, tensioner and tighten all your bolts, rotate the motor over a few times by hand and then check to make sure the alignments are correct. Sometimes you may be a tooth off and have to redo the alignment.
