10 850 sportsman clutch issue

I am new to this forum, I just bought a 2010 850 xp, when it warms up it seems the belt is to tight. it will back shift so hard it will drag the tires. Also when it is warmed up it will put so much pressure on the flywheel is scrapes the starter, and if you run it in park or nuetral, rev up the engine it will kill the motor when the rpm’s come down to an idle. I took the primary clutch apart and found no wear or damage. It acts like the belt deflection is just to tight. The belt looks to be in good shape. the machine has 1200 miles on it. Any suggestions would be great.
