Have a problem with the oil ring and pulling the piston out and am looking at putting a JE 10.5 piston in. What do you think about cam change.

What is the deal with the 488 kits, who sells them and how much power do you get.

Last question is the hmf or gymz the only exhaust out there?

well .... i have the 488 kit, and a hmf pipe..... had the hmf first...it helped power wise..... but not a ton.... the sound is great and i am happy with it..

as for the 488 kit i only have about 75 km on it so far but what a difference......pulls the wheels up with my fat **** on the seat now.....mid to top end is so much better....
i might also mention i have the haauck clutch work done.....that is very impressive to....

fst 488 kit you get from mickey dunlop at four stroke tech google it....hope that helps
