Been lurking on here for awhile and have not found the answer to what I need !! This past summer I bought a 49cc kit from a kid for 35 bucks and I put it on my bike ,took my time and did it right ,when the fist time I tried to get it started the case behind the clutch cover broke off and I JB welded it !! Haven't tried it ,I didn't think it would hold!!! My question is would it be cheaper to buy new cases or just get a new kit and save old motor for parts ??!!! Thanks
