i have a little extra cash laying around and i am wondering if twin pipes are a good idea for my sx twin. the motor 100% stock besides wiseco pistons. i was thinking v force reeds and maybe thinner head gasket but does this really make a noticeable difference? i realy dont want to put twin pipes on it but i am considering it to get a little more power but i hate rejetting motors i had enough of that with my methanol bike this summer. do i have to rejet for the head gasket and reeds if so how much should i bump up the jets?
