2001 Sportsman clutch engaging too soon? Extremely difficult to shift

For the second time, my 2001 Sportsman 500 with 1300 miles total, is becoming very difficult to shift from from neutral to/from hi, low or reverse when the motor is running at normal idle speed.  When I do "jam" it into gear, the bike begins to move immediatly.  Using the brakes to keep it from moving, slows the motor to such a slow speed that it dies.  When the motor is off, shifting is easy.  I think the clutch is not dis-engaging (again)

When this happened the first time, the local shop said the drive clutch halves had grooves worn in them.  They replaced the whole drive clutch, $420 plus Labor, ouch!  They told me to use low gear more often, to prevent the belt from wearing a groove in the clutch halves when the motor is pulling a heavy load, such as driving onto a trailer, or up a steep incline.  I tried to follow their advise, but now, 300 or so miles later, the same problems are returning.  If I start the motor, I can't shift in or out of gear.  If I start in gear, the bike  wants to move even at low idle speed.  It is VERY difficult to shift when the motor is running.  If I brake to keep from moving the motor dies.  

Has anyone heard of the "grooved clutch surfaces" problem.  Is there something else I shouldl try?  Are Polaris PVT clutches really so easy to wear out?  

Thanks,  I hope to not have do another $400 plus labor repair!

Thanks,

You need to remove the clutch cover and watch whats happening. If the whole clutch is new then that cant be the problem. Perhaps its a broken motor mount causing a misalignment. Also make sure you have the correct belt installed.
