K&N filter question

[vroomy]

hey guys im about to put a K&N filter on my wifes 09 fuel injected z400, just wondering if ill need to have the engine cpu re-mapped? im leaving the airbox lid on too... and i may later put a LRD or similar slip on muffler so any changes needed for that?

Should not need any changes for the filter. You will need to buy a efi controller for the aftermarket pipe more than likely. Remember your giving the motor the ability to breath more freely and doing so requires more fuel. It is the point of the mods, so you want to make sure your give it what it needs so you don't burn up the motor.
