what's the recommended or best plugs to put in my rr4? Also, if I put a k&n air filter in, what difference will it make and will it need power commanding? exhaust flaps are already disabled
A power commander is a great mod, especially if you get it set up, Peterboroughs not to far from you, check out BSD he will put your bike on the dyno and do a custom map. Well worth doing
he set up both my r1's mate, use him regularly. just wanna see what difference it would make before getting it done
