team clutches

I just got a mountain cat and I love the sled but I have had some issues with varying rpm, at first it would pull 8150 and sometimes drop to 7600ish but now suddenly it constantly revs 8300+ and I can't figure out why. Also the sled one time idled at 3500 so it would slowly move, but I'm not...

Whats everyone getting for belt life on the team clutches on the 16's and 17's ? Coming off of a 2015 the past two seasons and now have a 17 MC. Curious on belt life.
