Looking for set ups guys are running on 09 nytro I'm running 162 camo extreme and looking to ride on the prairies of Saskatchewan Canada and out west in the rockies. I hear stock will work at high altitude but what set up is everyone running on the prairies? and why not what works up at altitude too!! NO B.S. lets just list set ups and everyone will benefit

Holy...thats pretty demanding!!!
Low altitude clutching set ups won,t work at higher elevation cus your making 25-40% less hp....pretty simple stuff!!!

Believe it or not, the stock elevation settings on the MTX work well in the prairies with my 153" challenger.... but still short at elevation. Haven't figured it out, short rpm's on long climbs gonna drop a gear this year and see what happens!

That's odd, because stock elevation settings are set for 10,000 feet according to the Yamaha manual, so you should be seeing just the opposite. If anything, your clutching should be out of wack in the Praries, unless their elevation is well above sea level ? Your report just adds to my level of confusion as to why Yamaha sets these sleds up this way....

I have an 08 mtx and found out the hard way that Yamaha had a thing called high alt. comp. Yamaha had shipped some sleds to dealers with high alt clutching and if your dealers are'nt on the ball it slips through and the buyers werent even aware.
I found this out when riding the sled at sea level and bumbing the rev limiter all day. I do not know if they did this on 09 units. When in doubt better pull the primary and see what ya got.

Mine had the stock elevation clutching from the chart, as did another friend with an identical 08 MTX and they are both strong here.... But in 7k + always short rpm's. He had his clutched/geared by the dealer here and still short rpm's, I clutched mine and was better but still needs more so I am going to drop and gear and fine tune the weights.
Hey guys - I run 3.5g in the tip - middle empty - heel empty and can keep a level of performance up to about 8,700K - then it's a mutt. . . .but then again we're starting to talk the hp of a 500fan at that elevation. . . .which brings me to my point of clutching and gearing will of course only get a guy so far :exc: . . . .after that you just need more ponies. . . .
I feel lucky. My dealer sets up the clutching on every sled before they leave the shop. Of course we ride from Sea level to 4-5k. Clutching for us is easy,,,usually.

You are lucky, assuming that set up doesn't cost extra. Mine is going to cost an extra few hundy for the sea level clutching/gearing, and I hear I got a deal compared to some ! Personally, I believe that all Mtn sleds should be set for whatever elevation the customer needs, and it should be covered in the dealer set up/pre delivery fee, one shot deal only. If you want adjustments down the road, then the rest is up to you. My 2c
Just read the clutching chart & add $10 worth of rivets. They both use the same weights but more mass for sea level. The dealer is charging you a few hundred bux for $10 worth of clutch rivets???
For my dealer it is included in the set up when they un-crate the sled. Doesn't matter if a short track already out of the box or a mtn sled. Of course anything after that is out of pocket.
Sounds like I am lucky enough to have a good dealer.

Turk and swelly, the Nytro MTX elevation chart suggests a gearing change(and requires a chain change) for low elevation so i imagine that's where the extra dough is factoring in.
In saying that, I left the gearing on mine alone and have no plans to change it, so all I did was buy rivets and a primary spring. (and put a 51/43 helix on).

Yea I would say pretty demanding for a newbie yet. How about a Hi everyone could use some help here with my clutching.
They did not change my gearing at all. Nor was I trying to rustlle any feathers. Mine has worked well out the, except for the track, the c extreme will go on next week.

Clutch rivets, top gear, 70 link chain, primary spring, gear oil, etc. At least that's what he told me. If I knew 110% what the stock gearing was (18/40 or 20/40) that would make a huge difference in my decision and the costs, as I would leave the gearing alone if it were 20/40, however, the chart says otherwise. (and some guys still disagree with the chart)
