Ok I know oem is normaly the best but a freind and I seem to have the same problem chunks are missing out of the top about 6" or so mostly just trail ridin with family like to play to It seems to be 1 a year belt seems tight to specs I have EPI maroon/almond springs. Anyway has anyboby had good luck with dayco hpx belts or em I wasting my money thank for any input

 

OEM belt seems to be the best. I have a few CVT driven quads and they all still have the factory original belt with 500+ miles. The oldest one is 2004 P700. Try to use low gear whenever necessary and don't try to rev too much when wheels are stuck - use a winch or some other means to pull out. Riding pattern seems to affect the life of the belt more than anything else.
