Hi guys, I joined this site to hopefully help out some friends of mine. We're from the midwest and heading out to West Yellowstone this winter to ride some trails and some off trail. We ride newer Skidoo's with etecs and all we need to do is adjust pin weight and change spring to run out there. My friends on the other hand have the following sleds...
1997 Yamaha SX
2002 Yamaha Viper
What is needed to run these sleds out there? They don't want to break their wallet so any help would be great!
Thanks,

I dont know if your allowed to run those older sleds in Yellowstone. You may want to ask around to see what the restrictions are.

If you look in the tech manual pages you can find the altitude settings for the sleds. you are going to need to change jetting, clutch calibration rivets and primary spring.
