supertrapp and getting a K&N.

 

Thats hard to say, after you get the K&N get a few jet sizes bigger and start off rich and work your way down by the way it is running and checking the plug.

 

thanx

 

its hard to say. Jetting is one of those things that will take a while and there is no right answer for every bike. Each bike, even if it is the exact same might be different in some way based on where they are and what mods are done to it.
