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.
