I have a 2013 Polaris Sportsman 850 XP that has had serious problems since I bought it.The 1st problem is The clutch howles and screeches,I've taken it to two different Polaris dealers that have claimed to fixed the problem by changing belts as well as adjusted the clutch,only to have it howl and screech less then a week later.After that I took it to another dealer,that supposedly fixed the problem by changing and adjusting the cultch as well as installing another new belt.Now the problem reoccurred,less then a week later,and now it's shifting really hard....I would to know if anyone else has had these issues and what you(or your dealer) done to fix it.Thanks...
