Remember Rob, - it's not just a 904 wiseco kit you're running. That head you stuck on there had major valve work done on it. Then you're running the British Customs Stage 1 "Street Cams." So, you've taken that thing to a pretty high level of torque. I'd call Barnett (before those plates get worn) to see if they can suggest even heavier spring (perhaps some die springs).
I hope you have a Superman grip to pull in that clutch lever.
Man, that thing must have some serious roll-on power!
