Hi! Just found and joined this forum. Looks like a lot of good information here! Got a '96 Ski-Doo Formula SLS that we're changing over to high altitude (7,000 to 9,000 ft.) from it's former life in Minnesota. Got the carbs rejetted and it seems to run nice and crisp. I need to know what clutch adjustments should be made-I've never done anything beyond change the belt so any advice is appreciated! At what RPM should the clutch engage? Right now it's around 4200 RPM. It was suggested to use a yellow spring in the primary clutch. Anybody know what's likely to be in there now? (It's stock.) Thanks for any help! Allan

if all things are equal, u'll need lighter weights in the driver to keep up rpm's. y'r motor is goin to lose hp the more u climb in elevation. 6 hp per 1000' i was told.
u'll need to change gearing as well, but y'r chose.
