did you install the cam timing on the top dead center of the motor. and not on the compression stroke. ive got one mine run great have not had time to ride it yet but u can tell the power in the motor revs.
I had the same problem,called hotcams they said to set the valves at.006 for intake and .009 for exhaust. But they still made a lot of noise call the shop and hotcams again,hot cams said to reset the valves to .005 intake,.008 for exhaust.This helped a lot you just have to ride it easy for a while to reseat the valves.
