Any one know what *jetting and clutching I should be running in a 2002 Rmk 600 at *+1700 feet. The sled is setup for high elevations, *Stock how many feet is the jetting set *for? *http://www.snowmobileworld-s2.com/forums/iB_html/non-cgi/emoticons/biggrin.gif

Elevation- 0 to 2000ft if temp is between -10 and 10, 420's #3 on needle. *Temp between 10 and 30 above is 400's #3 on needle. *Clutching for 0 to 3000ft is Dk blue\white (drive clutch) Driven clutch spring-silver/blue #2.... Hope this helps, oh I think stock jets are 430's with the same combo for clutching.

AlaskanGold what about the weights. *It will be run to as cold as 30'C what is that 'F any way?

Shift weights are 10-58, if your running that cold then 440's with #3 needle for -34 to -23 Celsius, same clutching.... -23 to -12 celsius is 420's #3 needle.... Keep in mind the jetting is from Polaris and is probely on the rich side so after you run them for a while you might be able to lean down a size.
