Yea the cheapest I've found for good bearings was some skf bearings for 50 bucks on ebay I think with a gasket kit if I remember right. Just havent had the extra cash to rebuild those yet. Not sure if the 372 is worth rebuilding. It needs quite a lot of parts. Entire top end bottom end, crank,chain cover,recoil, kill switch, and who only knows what else,the o ring behind the clutch spacer,and I'm sure some other odds and ends. I'd like to take eit back to factory x torq and test it against my 372 clone that is non x torq.You can pick up quality fag ska timken a host of quality manufactured bearings for 8 bucks. If you’re paying more than ten someone just took you for a ride and you payed for the gas oil and food
