im rebuilding a stock yamaha 660 rhino. i have the crank out. i was going to replace the wrist pin and needle bearing on the the crank/rod. after looking at the current rod (stock rod) it looks to be in very good condition. no blueing or discoloring at all. i checked the up and down movement of the rod. i get .0035. i have looked at the manual and have not seen a spec for that. does anyone know what the spec is? before i rebuild a good crank i want to know this is bad.
