If your rpms are up there and then fade off like you say. # 1 cause for this is weak springs

She said she clickered up and rode in different snow and it was fine. Don't see the need for spending $$$ if she used the clutch in the way that it was designed to, and gained the RPM back. Yes I agree with maintenance, you know that, and I fully agree with cleaning the clutches and inspecting them, but I don't agree with chasing phantom issues or buying a clutch kit if there isn't an issue.

15% power loss from 3000 to 8000 ft (basically the elevations she rode that day) and probably more on a hot spring day. No motor can compensate for 15-20% power loss and not lose RPM, its basic physics. You are losing RPM for sure up top, whether the stock tach is sensitive enough to pick it up or how much you are overreving at the lower elevations is not being noticed, it is there. Maybe you are not riding as big a range of elevation? To pull the same RPM at elevation (with no adjustment) the motor is making the same HP at elevation with less air density. Impossible unless you have a forced induction motor. Science has proven it time and again.

For many many many years people have changed clutching to compensate for altitude because of this loss of atmospheric pressure, now skidoo has a miracle sled that doesn't need adjusting? Why were quick clickers invented and so successful? probably because people needed a faster way to adjust the clickers...If no one was adjusting the clickers, there would be no market.

Not uncommon for me to see 7600 at the truck and 7000 at the top in one day, just quick clicker up 2 or 3 and off I go, that's the whole point of them I thought. Don't know about going just going up or down one clicker, why do they make it so you can change up to 6 positions if you only need 2?

Stay cool dudes :D.

:cool:

on my sled i never touch them. simply because i set them for elevation and im not a hero on the way back to the truck lol.

so if my sled works at 8000ft on clicker 4 then yes id be overreving on the trail...but if your overreving on the trail....slow down :D

but forsure from parking to 8000ft you will lose 400+-rpm if you havent accounted for it already.

to me the trail ride down is like the NHL'ers hitting the bike to cool down after the game. therapy....clickers go down to 3 and look out....cause I'm comin' :d

I seen this in action, then re-installed my side panels that he blew off roosting past me at warp chicken. BUCK-CAW!

Hi Rowdy, If that were my sled, I would remove both clutch's and take them apart. You will need to find someone with knowledge and tools to do this. You can take it to a dealer and have them refresh it to factory specs. This may or may not be expensive, depending on the dealer. Some may want to sell you a complete new clutch. This may not be required. Generally the rollers are the culprits. It may need a roller or 3 and or new springs and ramps. Bushings also. Secondary may need new sliding half bushings. A new belt also. For piece of mind and if the sled is in good condition, this will help to keep you from the big stuck out in the back country. A clutch kit will only be of benefit to you if everything else is good in the primary and secondary.
The engine may not have the pop it once had to pull the pin-weight if you are having to run at clicker 6.
If you get the clutch's restored to factory stock and want to run on clicker 4 at elevation, you will most likely require about 2 grams less pin-weight from the stock setting. I find that running in clicker 2-3 here on the prairies with my little teeny tracked renegade means running clicker 5 at 7-8000 feet elevation. I had to reduce the pin weight in my primary 1 gram to get the rpm right where I wanted it as it came from the factory. This is personal preference.
How is your belt wear? This will be the next area to look at once the clutch's are in good shape as alignment is another important factor in getting the best performance from a summit at altitude.
Your engine will lose 3% of its horsepower for every 1000 feet rise in elevation.
Once you have it dialed to your personal preference, its just a matter of twisting the clickers(Motts are the best) at the cabin and go ride.

cheers

I'm the same way! turn out my shockwave and turn down the boost about 10 clicks and let er buck! coming down is half the fun of going up to ride!

love the ride back to the trucks, renshaw is an epic one....30 clicks and usually in the dark. the rougher the better....lol....weeds out the wannabes pretty quick :d

met the groomer coming down off Allan once, that scared the chit outta me. had 'er locked into a full slide and then up onto the berm at the last second to avoid piling into his blade. trail was sure nice the rest of the way

Dear maxwell,

I have discovered modman is pretty much the Chuck Norris of sled stuff, and you are way dumber than he is, But it is rather amusing watching you pretend you know what your talking about in anticipation of modmans response, Then....SHAZAM!............That is all.

Maxwell-I wonder if I can climb that SH%T?

Modman- With the current amount of forzen precipition located at 6-8000 feet on granite / slate at a 50 degree downslope of g-force, I do belive if I apply ample throttle pressure at the y vector and compensate the wind ratio... My current rate of ascent should reach the desired achived altitude.

hah! maxwell never second guesses himself. I saw him fly up a hill with that "Arby's" sign hovering over his head once....
