RE: OS 1.60 question
Update, Got the new bearings and installed them. The high pitch/knockning noise was still there. So I broke it back down. This time I found the rear bearing is spinning on the crankshaft. You can slip the bearing all the way on by hand and freely spin the inner race around the crank. I am pretty sure you should have to press it on. I need an expert opinion on this matter before I have to fork over money for a new crankshaft. I heard Locktite makes a product to fix this problem.
