Where are you planning to ride and what's the elevation. I ride out of Bozeman/west yellowstone and start riding at about 6500' I have friends that come from Minnesota And they have started calling slp for jetting and clutch setups that come pretty close with only minor adjustments needed to make their sled purr I can tell you my 99 700rmk runs stock jets, air screw 1 turn out and the needle set all the way down(clip at top) I run 60gram weights with a Square almond primary spring, a50/36 helix with orange spring. Also slp pipes,heads,boost bottle,Boyesen duel stage carbon reeds and stock track(136x2") I have never meet a ski-doo that will run with it, this is a great set up up here. By the way this is now the wifes sled and MY 800 just runs with it. On the hardpack I see nothing but the mudflap, deep snow I have a track advantage. Spring riding she carries more track sped so can out climb me. Thats the setup that works on my sled good luck and let me know how it goes. It has been snowing in the mountains south of here and the snow is approaching stuck level so I will be doing my best to test and track as much as possible this weekend.
