can am outlander 400 clutch issues

[Dier hunter]

the drive pulley on my cv clutch seems to be getting a lot of wear on the bottom part of pulley. almost like the belt rides there to much, would a spring kit change where the belt rides on the pulley.my riding style is pretty moderate, only giving it full throtle when it needs it. oh and i run 28" mud hogs,if that matters.
