why are you running a hi volume pump? that is probably whats causing the failure. you need to get a specific dizzy shaft.

High volume pump and stock shaft = breakage. All books and build ups ive read say the high volume pump is not usually necessary, but always upgrade to the higher quality shaft. Cheap insurance.
