Gearing for 2006 summit 800X ??

[River Ratt]

My 06 summit X 800 has a 151 track with 10 tooth drivers, manual says it's supposed to have 19 - 45 gears, I pulled the cover to inspect the chain and it has 21 - 45 gears, I bought sled new, but it was snow checked by someone else ? I wonder if dealer changed gears or is the manual wrong ? I am now putting on the 163 track, anybody any suggestions on what gears to run ? I mostly ride powder in Revy, Golden BC area.

I would go 19/47 and switch to a 15 wide chain. That is what I use on my 06 159x with 9 tooth drivers

 

[River Ratt]

Thanks for the reply, that's some real low gearing.

POPPS how do you like that gear combo? i'm doing the same thing on my 07 800 but its a 144 and a friend said to me that he thought that would be to tourquey, did u notice a big difference?

 

[Snoclo]

POPPS is right!

He's right, I also switched my Rev X from 144 - 159.
Went from 10 tooth drivers - 9tooth drivers and gearing 19/45.
If your going to run 163" make it 9tooth drivers with 19/47 gearing, this will be much easier to clutch and easier on belts.

i know stock gearing for the 06 159 was 19/45! i had it geared down to 19/46 and it climbed better!

If you ride Revy--stop and see Turboal at the Sled Shed--he will have the gears and the clutching for that machine and get you spot onMake it run HARD!!

Why drop down to the 9 tooth drivers, just to reduce gearing even more ?

 

[River Ratt]

How much are drivers these days ?

I run the PG area 3,500' to 9,000' on stock 800R 07.

Changed gears to 23/43. Changed track up to 162 last winter and still same gears. Awesome. I try to avoid people that have low gears as I always have to go help get them get unstuck, and its not their fault really. They just get stuck so fast they can't help it. As the sled slows up the clutches shift down, the spike in torque to the track rips a hole in the snow and there they sit. And I'm usually right in the middle of a beer looking down at them because they are going to dooooo like me.

Go low gears and go away.

Interesting, I think I will just leave the 21 45 that's in it for the first ride and see how it works, one buddy has a 800 dragon 163 and one an xp and the other m8, last just I was just behind them with the 151, so I'll see how she works first ride.
Thanks everyone for the input.

Thats quite a difference from 23/43 and 19/47,i haven't taken mine apart yet so i wasen't even sure what the stock gears are,i thought after 1400k i would try some different combo's this year,so i switched out the rollers on primary to 2mm oversized and went to a heavy spring in the secondary and a different helix. I ride in between 6 and 8 thousand feet most of the time.

gearing

2006 models

800 summit adr. 151/16/2 had 10 tooth and 19/45
800 summit X 151/16/2.25 had 9 tooth and 21/45

The X sleds need a 20 top and the adr. sleds need a 46 or 47 bottom-BJ

How about you opinions on gearing and clutching for stock 05 800 with DJ's clutch kit and CamoX 2.5x16x150, ride only in mountains 6,500 to 11,000ft. Changed drivers from 10tooth to 8 tooth, and gears from 19/45 to 22/45. Problems Last Year: leaving 1 1/8" of "Sharpie" on Clutch face, Eating a belt every deep day, and 35 mph max. pinned uphill in deep snow, California snow! Would be stoked with any help from DJ and any other Mountain Guys

You probably have to gear down some more. The TRA seems to like the middle of the face, TRA is the only clutch that makes big use of heavy springs so that is likely part of the limitations. Or you might have to gear up a little more if the 8 tooth has broght the range down too low.

You can't really count on the track speed in the lowest clutch ratio as the TRA is too unstable in the bottom and will hunt. Again either the springs or some effect from the rubber mount in the clutch face.

I doubt you are going to get any more that 35 mph at that altitude in lots of snow. The difference is that if the primary would run in low ratio you would get more torque to the track and go farther without blowing a belt.

One of you riders in the high altitude country should pick up a Polar primary and see how it does. I run at a lower altitude so I'm putting lots of stress on the Polar clutch, but at your altitude there is less horse power to the primary. The Polar will run in the low ratio no problem and won't blow a belt.

Too torquey ???????

POPPS how do you like that gear combo? i'm doing the same thing on my 07 800 but its a 144 and a friend said to me that he ["]thought that would be to tourquey[/, did u notice a big difference?

I doubt if it's possible to build an 800 with too much torque, I would like the opportunity to clutch around it though. I didn't change the gearing very much, it came stock with 9 tooth drivers and 19/45 gearing. I use a 130/290 spring so I find poking around in the trees very easy but when you come out of the trees and the hill is right there, mash the gas and hang on. My roller secondary is all stock but I do use 1 mm oversize rollers and enough weight to acheive the RPM I want. This setup doesn't backshift abruptly like Yampolcat thinks but actually hangs in there maintaining the track speed in the steep and deep. Clutching is critical, you must know what your sled is trying to tell you and make the neccessary changes. You can have two identical sleds, geared and clutched differently, and get the SAME results on the hill, so gear and clutch your sled to the way you prefer to ride.

Big John what gearing do you think would work best once I put the 163x 16 x 2.25 on.

Interesting, So your clutch doesn't back shift when it is under maximum load. I guess that would work, and why not. Just gear the sled low enough so the belt will never hit the bottom of the primary. Just keep lighting up the load on the motor with deep reductions in gearing until the motor is able to keep the belt in the middle to top of the TRA.
Now I see what you fellows are dooing. Interesting compromise needed to run the TRA, but seems to be the only solution alright. Because if you gear higher the belt goes up like a candle.

I'm about as likely to listen to what my clutch is trying to tell as I am to get in touch with my inner self, so it's no wonder my TRA spends lots of time on the spare parts pile under my work bench. I don't listen to my sleds excuses, I just fired the problem.

Priceless!
