I have a 95 Mach 1 670 with twin pipes. when the sled is cool my rpms are right at 8000, as it warms up my rpms drop right off, (7000rpms) ,,could this be a seal, it doesnt seem to be overheating, your info is appreciated!

Hey krkman, if you check all your clutching, my specs for the '95 Mach 1 say you should have the following: Prim. pink/white spring (230/380), 285 ramp, solid pins (16.4g), set at #3 clicker. Sec. beige spring, set at 12-15lbs. (try A-1, C-1 or C-6) in a 47 or 50 helix (I don't have specs of the helix, but I'm guessing that's what you should have). If your primary has all those parts, then check your primary rollers to make sure they spin freely and don't have alot of play in them. Also check the pucks in your ramp cover to make sure they are not worn out excessively. Clean out all dust from primary with compressed air. I think that if clutching is your machines problem (and not a mechanical problem), I'm guessing the problem is either the secondary clutch bushings, secondary spring preload is too low or secondary spring is sacked/finished.
Hope this helps!
