This is cool to see more people converting to the new 17" wheels, one method or another. Ed Sorbo is a great source for information at the track, he has been helpfull to me and a friend who race Ninja 250s, but I had my pre-gen converted to the new wheels before I talked to him at the track.
More power to the conversion movement with the Ninjettes!
Maybe more trackday guys and potential racers will follow when they see that you can make a "pre-gen" 250 every bit as capable at the race track for half the cost!!!
