hi, i am looking at changing to a free flowing exhaust and K&N air filter to let more air in and out.
since the bike is fuel injected do i need to do anything with the injection system or will the sensors accomodate the mod?
the bike is a 400ie monster and i am aware that it wont do much, if anything for the power but it should make it sound sweeter.
