With a new K&N filter is a jet change going to be needed or will it even help with leaving the exhaust stock and what would happen to fuel milage with the jet change and what jet to change to. I ride between 2000-5000 ft.

Most of the time you do not need to rejet with a K&N filter. If you are concerned about the jetting check your plugs and make sure its not running to lean.
