Hi i have a problem with my 2010 Sportsman 500 HO the problem i have is that the drive clutch is not sliding in consistantly in H gear its fine when i'm in park and reving it but as soon as i get on an put it in H and take off it revs very high and wont pass 30mph (at first i thought the belt was slipping)the drive clutch won't engage all the way,i've had the belt off and it push's in on the spring fine as i said in park all seems to be working.
Have i got a problem with the weights or is the problem with the H gear?
Dose the spindle that the drive clutch slides on need any lube or something?
I'm completely confused so would appreciate any help.

Chinno.
