Just put an SLP pipe & can on 600 H.O. any thoughts on clutching changes? I have a heel-clicker in it now & SLP says to run MTX 65 gram weights which look very similar to the heel clicker weights. Also going to add SLP Air Horn intake & possibly the hot air elimination kit. I have been told to change gears too, but it seems like an aweful lot of changes at once, possibly going to either 22/39 or 22/40. Any suggestions would be appreciated.
