I did some research on something called the wheelie wire, didn't believe it until I actually read some convincing post, from a rock solid source, the factory actually installed this to retard the timing, don't know exactly how it works but I do know it exists! This wire runs along side the neutral safety wire down by the kick stand. The wire you're looking for is black w/red stripe, I believe all you do is cut the wire and ene cap it!
