I am a adding a new cam and piston to my wolverine. Should I get a clutch kit or port my head? I also plan on changing my carburetor and adding a new rev box.

 

I really like my epi clutch kit, I will be adding a new cdi when they become available. If I had the engine apart to replace the cam and piston I would port my head, you can do the clutch kit with the engine in the bike so I would do it later probably.

 

Were did you find a cam and piston for the 421cc engine?
