High-Altitude riding - 600 twin sportsman
I am planning an ATV trip in colorado this summer. I recently purchased an 04 600 twin sportsman (that I LOVE) to replace my old POS 2000 Grizzly.
I'll be riding up to altitudes of 12-13,000 feet. I currently reside at about 800 feet here in the midwest. Should I expect to have to do anything to make my sportsman run correctly at the high altitudes?

Jet down.....10-11 sizes. Thats what i do with my sleds when going out west. for every 1000 you go up jet one size down. I would bring a few different sets of jets with you to dial it in when you are there. Play it safe on the rich side though. Less oxygen up there...compensate it with less fuel. Also reclutch since you are loosing power at higer elevations. (Less Atmos. pressure.)

I'll be in the Ouray County area (hwy 550). Too bad I don't know much about motors, I dont think I'd know how to rejet if my life depended on it. I'm fairly mechanically inclined though so once someone explains it to me or shows me I'll remember it forever.
The clutch thing, on the other hand, doesn't make any sense to me [img]i/expressions/face-icon-small-smile.gif[/img]

They will tell you what jetting to use. As far as the clutch, if you are only temporarily going there to ride the alpine loop or something it is not worth the time and money to change the clutching. Yea it will be a dog but you shouldn't have a problem. I was out there in aug and only jetted mine and had no problems.

I have never heard of anyone changing the clutch for high elevation. What is the point?</end quote></div>
On auto v belt tranny it keeps the tranny in the prime rpm range. This is done by putting lighter counter weights inside the tranny so it engauges faster. Xtreem Powersprots in Longmont (Where I bought my Grizz) is known world wide for testing Snowmobiles and Atv as they put every machine on a dyno to get prime performance out of each and every bike/sled they sell!
