Some sleds eat belts but some sleds have well intending riders/ mechanics that assist them in excessive belt consumption. I've noticed over the last several rides that those fuming about the belt that only lasted 50 miles also were getting them wet through either riding around with their hood off in the powder pretending to be adjusting something (showing off their newly powdercoated twin pipes) or putting in too many vents that suck fine powder into the belt. The dog screen is neat but not fine enough mesh 1" from the belt. Wet belts break down fast. Rubber needs to be fairly warm and dry to work right, that's why dragracers do burnouts and Nascar drivers zig-zag behind the pace car on the opening lap. Just a thought, what say ye?
Blowing belts? Here's my theory

i beleive the problem is misalignment 
nd when fixed the belt problem will disappear...jmo

I have had a bunch of belts blow and none of the wet problems as described applied... as I study the problem it appears on the XP it is caused by, 1) Misalignment, 2) Poor primary clutch setup (too stong spring and not enough pin weight), 3) Belt needs to be wider (to resolve the deflection problems) and finally 5) Too tall gearing
The XP is second only to the 900 Polaris for gobbling belts (around here) . Too bad, it has a lot potential. The new 800 Dragon seems to like belts too.
So if there was a problem with snow dust/water on the belt/clutchs is it also possible that the resulting slipage is causing a quick overrev which is creating some crank problems as well?

So, I ride a M7, not the most agreesive rider by any means, but climb a lot of hills, ride Baker, revy. Whistler and many other places. Never had to replace my belt, I believe it's all about how your set up and your clutch alighnment. I don't no sh!t about it just my opinion.

I dont think that gearing is the issue. We have 2 with no down gearing, but added pin weight, cut the secondary cog so the delfelction STAYS where you put it, and added venting ........ 1 has 350miles, one has 550miles, original belt with riding in WFO deeppowder.

for what it's worth
heat, misalignment, & deflection. Heat (caused by the previous list) are the biggest killers. Keep 'em straight, clean and at the proper tension and you'll be good. I had a 900 hundo and after getting good mounts in there I ran the same belt all season. Tires fail & wearout prematurely when the inflation & alignment are not correct. Apply the same principles.
