Getting ready for the mountains

Hey guys, looking for some tips/advice. I am heading out to the mountains for the first time this year (looking like West Yellowstone). I am looking for suggestions on suspension settings and mods that you would suggest for making my sled somewhat capable in the hills. About my sled:

08 RTX (40th Anni) that is extended to 144" with a 2" challenger track., SLP powder pros, it is also geared down and has extrovert drivers on it. For clutching, it has a heavy hitters kit.

I am assuming I will need to drop my weights down in my primary. Are there any suspension adjustments that I should make to allow the RTX suspension to work "OK" in the deep stuff? Any other "must have" mods? Also planning to carry some extra fuel as I can guess that is pretty much a necessity.

Thanks for the help. I don't want to spend a ton of money, but if there are a few cheap, quick mods that will make the trip a lot more enjoyable, I am all for it.

What gearing change did you make, and what tooth drivers did you go with?

8 tooth drivers. I haven't verified the gearing, the guy I bought it from said he dropped it a tooth on the top gear.

Looks like you have the necessities covered. I run a similar set up in the mountains (with less track actually) and it works well. One thing I wouldn't go to the mountains without is a roll over valve. My buddy found out how important it is when he tipped his over and lost most of his oil. He had to borrow a sled and ride down to get oil. That ate up a good chunk of the day. It also comes in handy when you are stuck and need to roll the sled out.

Yes you are correct that you will need to drop primary weight. How much depends on what altitude you will be riding at.

Got avy gear? (beacon, shovel, and probe)

If not save all your money for performance and get the gear that will make a difference in life or death, not just 10' higher ona slope...
 
Call up Scott at OFT for their roll over valve/ tether kit. You won't lose oil when you tip your sled over. These are essential in the hills and also useful in the flatlands.

I agree with mtdream...

Avalanche equipment and if possible before you go out training of some form would be good.

Mike Duffy puts on avalanche training specific for snowmobilers throughout the country. He does a very good job and is well worth the $49 to learn and understand things that may save your life or someone else.

His website is http://www.avalanche1.com

There are some good links and lists of what avalanche gear is good to have.

As mtdream said, a beacon, probe and shovel are minimum.

Merry Christmas from the Curve Industries family to everyone at the TY family! Have a safe holiday and snowmobile season!

You can also rent avy gear at reasonable rates. We rented for a few years before buying everything.
 
Can't stress enough about getting avy gear. Make sure you build a good tool kit too. Never know what can happen when out in the middle of the mountains. I also carry extra gloves, socks and a hat. I believe there is a good thread on what to carry in backpacks somewhere on here.
 
Thanks for the advice. My buddy told me I could rent the avy gear. Any changes to the rear suspension that will help trenching? Thanks.

Pulling up your front limiter straps one or two holes helps reduce trenching, by reducing the track approach angle.
You can also back off the front skid spring pre-load some as well.
Not sure what you have for skis, but wider mountain skis will help big time!

For clutching, the clutching chart for the elevation you'll be riding at is a good place to start. Only instead of installing the heavier rivits in the tip of the weight, put them in the heel and go light in the tip. This helps the primary clutch back shift better and gives you a straighter shift curve for moutain use. ;)!
 
Great Thread!

I am doing the same for the first time. Hitting up Cooke City in late January. Need to make sure my sled is ready. Only have a backcountry track though.

Not sure if I will have to change anything in the weights with my super rats. I am currently over reving and thinking with higher elevations my revs will come down where they should be??? I do have the mtx skis.

I am hitting the rev limiter at 9300.

At high elevation you might be pretty close then. Of course the only way to know for sure is to try it and see where the RPMs come in at. Snow conditions can have an effect on RPM as well, with wet heavier snow pulling the RPMs down some when compared to dry powder.
What I usually do is keep a log of the different set-ups for an area that I know that I will be going back to.
