Biknut..tell me how that magnet works. I saw it a few weeks ago and was interested in buying one. Have you heard of Jaguars' modified motorcycle C.D.I. that he sells? Its like having a real motorcycle C.D.I. but it works on 6 volts.
I haven't been clocked, or even have a speedometer. But I feel I am getting very close to, if not about 40. As it seems I am keeping up with traffic very well on the secondary routes. My bike is light, it's a Trek 3700 all aluminum frame, and weighs in at just over 40 lbs. Also, that's where the tune pipe really helps getting off the line and up to speed with the extra torque.

I have also noticed, that everytime I shorten the head pipe, it wants to rev out a little more. Although I have my pipe in the UP position, I have gotten to the point where I can't shorten it any more, because the head pipe wraps around the front of the downtube.
