The Bazza box is whats up. Forget the warranty and go with the turbo. If you ride on the street get the ek 530 zzz. It's the only one I've had any luck with on the turbo big bikes. The zvx works ok on the 1ks. Depending on what kinda torque you make, a lock up clutch is in your future. 1st and second gear will hold, but from there, they're gonna slip. Unless of course it's it's spinning the snot out of the tire. RPM makes a decent low cost two stage lock up. I don't know about the cams tho. Mine made better power with the stock cams degreed to 103 lobe centers.
