Hey guys, I have a 2012 Sportsman 500HO. A few weeks ago I blew a belt when driving down a normal gravel road. I noticed it was like slipping or loss of power then poof flap flap flap snap. I took the cover off and the belt was destroyed. I replaced it that day and went all day roughly 250km of riding on trails, mud and water. It was running good but noticed it had that bit of sluggishness or slipping when dry and when I went in water (not dead maybe 6") I could tell the motor was making a different noise or the belt area. Anyways was a good day and no issues. Then a few weeks later the second time riding my quad since belt replacement I was driving my quad to another town as I moved and on a dirt road felt my top end going up and down then poof flap flap so I stopped right away. I haven't removed anything yet but what the hell is going on! It's not even 1 year old my quad and this is happening plus the belt is less than a month old! Now I have put bigger wheels and tires 14" MSA M15 crusher wheels and 27" Maxxis zilla's (not mud zillas). I've had the wheels for a many months before the 1st belt blew so this can't be it at all (what do you think as many riders have big wheels and tires and never have issues). Now another thing my friend and I looked at was the oil levels. I've only had 1 service so far and we noticed the oil was wayyyyy above the full line would that cause the engine to over work and cause this to happen? I've reached my 100 hours so I'm going to slap my stock wheels and tires on as the dealer said to do this before because Polaris will void my 2000 dollar extended warranty and see what they can find. I've also heard my clutch springs or weights could be off or the engine mount is off? I don't ride my quad super hard. So any help would be great, thanks!
