Crankshafts for a single cylinder two-stroke engine consist 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 and the replacement crankshafts coming from China are a gamble at best. The record goes to a local competitor who thought that .015 was close enough. I'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. All of our crankshafts are assembled on our state of the art crankshaft assembly fixture. We built this fixture in house because there was nothing available that met my standards for accuracy. Every crankshaft rebuild undergoes two inspection processes before it leaves my shop. I guarantee my quality by sending a certificate of concentricity with all inspection data documented and then I put my name on it. My name is my reputation! I don't play games with motorcycle crankshafts and neither should you. Rebuild your crankshaft with confidence and
NEVER WORRY ABOUT GETTING A BAD CRANKSHAFT AGAIN!

The problem with getting your crankshaft rebuilt is that it always looks OK. Most people don't own the proper equipment to check the crankshaft when it returns from the shop. Motorcycle mechanics know this! All of my rebuilt crankshafts are assembled by a technician with over 30 years of experience.
