i am looking for information on bolt on's that i might order for my 2002 Kawasaki Mojave. i want to put on a Big Gun Complete Race Exhaust System, K&N Power Kit, and a different sprocket. i want a sprocket that will give me more top speed but I will still have enough low end to go up hills. what type of sprocket should I get? and how fast will these 3 mods make the machine go?
