around about when the high speed jet kicks in the primary clutch makes a grinding/rattling noise i took the outer sheave off and looked at it all, the only thing i could see was 1 of the 3 pins were loose, it looked to be a bit smaller or wore than the other 2, im not sure if this was causing it or not, and another question, i busted the track a few days ago, and i took it off and measures it and its 108 inches, i have another track off my friend which is 106 inches, with about 3/4" of adjustment left to make, will it adjust enough for it to fit?
