Owner of a relatively stock 07' classic except for radio/lights for about the last year. I have been having an issue with he check engine light eliminating but the bike never throws a code and runs fine. Checked with multiple scanners, tried multiple tunes. Even tuneecu shows that the engine light should NOT be on via dash board.
Now to the performance part of this post... I dig deeper trying to figure out why this light wont go away, I am under the tank and have to remove the air plenum assembly to trace some wires. What a friggin mess. Whoever designed that thing must be the dumbest smart guy in the room. Dont even get me started on how rediculous it is to put back together.
Anyway, I did it once and now know I dont want to do it again. Ordering K&N High Flow Air Box Eliminator Kit for Triumph Rocket III Online from Pure-Triumph.com as we speak.
Few questions for the masses, is a new tune required for high flow intake IF stock exhaust is still in place? Aaaand, it almost seems wasteful to put a high flow intake without upgrading exhaust, but from what I read in here is that most of the popular options for the classic have been discontinued and are getting hard to find. Any recommendations?
