I just inherited my wife's 98 600 sp. The wife rode it since new and it has 2300 easy miles on it. Other than routine maintenance I have not done much with it wxcept dropping the mains to 320 and tuning the carbs to spec. We live near Freesoil, MI and do all of our riding between here and Cadillac. I noticed that the sled would hit 8700 and at times 9000 rpm @ w.o.t. I weigh 200 lbs. (minus gear). I want to bring the clutching together. Does anyone have any se-up tips ? Oh also I noticed that with the oem belt it would rev to 8700-8900 rpm and with the Dayco it would pull more yet. I'm thinking of more engagement rpm and less on top. My polaris/comet drawer has been empty for years as I spent the last 6 years on a purpl doo. Ant tips/ comments would be appreciated.

8700 to 9000 RPM is too many RPMs, that thing should max out at approx 8200 RPM. If it pulled better with the dayco belt, but still revved so high, I'd say go with that belt and a bit heavier weight, 1 or 2 grams more will bring your top RPM's down, and it would probably engage at a lower RPM too. So to get your engagement RPM's up, as you said you want, you should get a stiffer spring put in there.

Another option is to go with an aftermarket clutch kit from Hot Seat Performance or Erlandson Performance, they come with springs, engagement spacers, weights and a helix, and to my experience with people who have them and have used them, nothing but good results. The only down side is a little bit more gas is required, but you will notice a difference with a clutch kit.
