I live in Colorado and ride my 09 scrambler at a 8500-9500 ft elevation on average.

I called up the local polaris dealer and he quoted me about $200 to setup the bike for these elevations which includes rejetting the carb and adjusting the clutch.
I knew about the carb but what has to happen to a clutch that is altitude related? and is there anything else that needs to be adjusted?

 

I would just get some individual jets, for a couple dollars a piece, and ask what the dealer reccomends, and do the jetting yourself, and as for the clutch, I'm not real sure on

 

On my 850xp, the clutch for high altitude comes with a different shift weight for altitudes above 6k feet.

hmm ok
I like to DIY my repairs so I learn as I go so i guess ill look into different shift weights

thanks

 

that high up you start messing with fuel/air ratios which will bring engine power down. you have to adjust the clutches in order to stay in the torque range to keep the tires moving at a decent pace

 

That makes sense.
Im having trouble finding High Altitude clutch kits for my quad so I might just end up paying them to do it.

 

I live in the Tahoe area and changing the shift weights on my Touring 500 EFI made a big difference riding at altitudes of 7- 9,000ft.

 

I'm taking my 08 700 EFI X2 elk hunting next month at 11,500 feet. I didn't think I needed to make any adjustments w/ an EFI. But what I read here made me call the dealer. He didn't recommend I make any adjustments. He asked if it was going to be permanently at that altitude. But for 10 days he didn't recommend it. Could it already be calibrated/adjusted for a higher altitude. The dealer is at 5,000 feet and I went hunting in January at 7-8,000 feet riding around at over 55 mph w/o a problem.

 

We ride at Pismo beach (sea level) and we ride up in the Sierras up to about 11,500 ft.

I put a Dial- a -Jet on my Scramy and that helped a lot. With the 800 EFI I don’t have to worry about a thing.

I have never heard anything about changing the weights on the clutch, but for as much as I change altitude I am not going to mess with the weights.

 

I also live in colorado, and installing the lighter weights made a difference. It feels more responsive now. Didn't notice any down side.
