I had the same track on my Ultra RMK. Quite frankly, that track is just not a good deep
powder track. It does fine in older, somewhat packed snow. Last season, I installed
the 136 x 1.75 Polaris track. Wow! What a difference! Deep powder mobility was
dramatically improved. I set the rear-end up to allow for as much weight
transfer as possible, limiter straps out and scissor stops set accordingly.
I realize that a track is a somewhat expensive proposition but it's worth it
especially if you intend to keep the sled. Check around in the bulletin
boards and you can probably find a used one. My dealer, Xtreme
Polaris in Castle Rock, sometimes has take-offs that customers
have traded in for upgrades. This is how I got mine last year. It
had about 100 miles on it so I got it for quite a bit less than new
and it was in perfect condition.
This year I've put on the 141 x 2 Camo Challenger, Tison rolled chain-case and HRP
suspension. Still haven't had it on the snow yet but I have contacted people
that have installed all of these parts on various sleds (Storms and Ultras included)
and they totally change the personality of the sled. Even these heavier triples
will float in the powder. Yes, this is a major investment and these mods are
challenging for the do-it-yourselfer but what a sense of satisfaction afterward.
Lastly, Xtreme Polaris has a web-site - www.xtreme-polaris.com
. They will
gladly ship even used parts and I would bet they have a couple used tracks.
Note that you would be able to install the 1.75 x 136 in your sled with no
other mods. The lugs will clear the bulk-head. You may notice that the
lugs will just brush the motor-mount nuts as the track rolls around the
drivers. I ran mine this way last year for over 1000 miles with no
