Crankshafts for a single cylinder two-stroke engine consists of counter weights, thrust washers, a pin, lower rod bearing and a connecting rod. These components must be assembled to exact specifications. Even .002 out of specification will cause vibration. Vibration will rob your engine of horsepower, reliability and it drastically reduces engine life!!

I've seen brand new factory crankshafts off by as much as .008 center to center. The record goes to a local competitor who thought that .015 was close enough !! We've assembled hundreds of crankshafts to specifications as close as .0001 !! This takes patience, time and experience. Don't trust this kind of precision work to the first guy you meet with a press and a hammer.
