I am looking to add horsepower to the quad but not go into the unstable big bore power world. I would like to keep it to bolt on power as I will be doing all the work in my garage.
I already have full Yoshimura exhaust and will be putting 450R carb on it when the work is done.

What combination do you recommend?
Piston Kit?
Cam Shaft?
Valves?
Am I missing anything?
