Oh I forgot to mention that there is a guy here in PG that has the same sled as you and he is running a Comet clutch. He loves it from what I hear. I do not know anything about those clutches except that you can get one from Royal Distributing. They say 468.00 and up for calibrated complete. Again I know nothing about them but if you sign up on dootalk he is yammadoopolcat I think. He would be able to answer any questions about it. I am not sure what you are thinking but i just thought it was another option. I am pretty sure you would lose your e-start and i worry about the harmonics thing I mentioned before, but you never know.
