Default Re: New engine just died

Yes there was a seal. It just came right off after taking the flywheel off. Didn't look like it would seal anything. If the supplier won't work with me, I'll probably buy some Japanese bearings and seals and rebuild myself. I've never had any luck in the commercial field with Chinese bearings. Too bad everyone is using them now. Electric Motors always fail. I did notice the flywheel key is the same as Gopeds and pocket bikes. Has anybody tried installing a "rocket key" (offset timing key)and advanced the timing 10 degrees? I've done it to 3 of my scooters and the acceleration gets bumped up a little.
