I don't know what is going on with the sliders on this machine but seems like that every pair i put on it seems to burn them out .and doesn't matter if the are from Yamaha i have tried them all.. hp ones right from the dealer or cheap *** ones. I checked the rails they look to be in good condition not bent, the Idler wheels all in good condition, nothing bent broken the track is not tight .but last year something changed. that all i can say.! this was never a problem before i could go 2 seasons without putting a slider on ? what gives?? funny how the go but they wear out almost mid point of the skid frame and around the front outside idler wheels. I just put on a new set and they are already done. and i have been riding in nothing but powder conditions this makes no sence i could see if i was riding on hard pack icey trails then i could blame it on that ..ahhh .now the work again to clean the track clips from all the melted plastic. I'm baffled i don't know what to do...... anyone..???? have any ideas what might be the Problem ?? Please Someone Help..!!!!
