Ok my 15′ 800xmr has 63 hrs on the clock, i forget how many miles. Anyways, the group went riding sat night, bike ran great as always but i knoticed that in 4×4 in the mud the motor felt a lil bogged down in the lower rpms, mud was soupy with rock bottom so i wasnt lugging on it. If i really railed on it i could get her into the higher rpm band and then it was fine, just seamed like it worked hard in lower rpms like round 1/4 throttle.

I got into a real nasty hole but was able to work the bike out, never had the motor going hard with iut tires spinning, next hole i burryed it, had 5 giys trying to push, i gave it throttle, probally a little to much and i heard the engine rev high and tires never turned, only for a second, smelt the belt and winched out. Never had smoke come out of cvt exhaust but every time after that from a stop when i go to accelerate u could hear a chirp chirp ehen starting to move then it would stop, the noise eventually whent away, i still had a lot of mud in the trail back to the trucks and she never let me down. Ive had that noise happen a while back but it whent away, and 1 time i got water in the cvt, not a lot but enough to make it slip, The rad cover over the cvt intake is good but when hauling ass thru watter and it rains down over it some got in the intake.

Should i change the belt or am i ok?
