163 xp, 300 miles, 80% deep snow with steep terrain.....so far, so good, knock on wood and all that stuff....bought the sled in evanston, wyo...sled runs very well, no problems....oil settings, clutchs and everything else setup purrrrfect....rode one belt for 35 miles to break it in, it's now the spare, the rest of the miles on one belt, still looks good....put a cpi single and can on it, works even better....sounds like i need to take out the drive shaft and have it welded (monday)...have a dragon (7), m-8 and m1000....overall fun factor of the xp is the best....rode with a dragon 8 twice, nice sled, but felt the xp would handle it in all conditions except top speed on a road...like the ability to get the xp to go anywhere i want it...NOW....ride on the trail is exceptional (we all have to have some trail time)....the 1000 i ride with has trouble matching the xp in the deep, steep tree filled canyons and mtns i mostly ride....i vented the sled very well, added flowrites to the back of the air box, with snow totally covering the sled it still runs well....i read that some are having issues with their sleds, not my experience to this point. so i would definitely recommend it
