i have a 98 trailboss 250 with the cvt automatic tranny and it has always made a terrible grinding sound, when i use the brakes is reverse. it is really loud and it vibrates my atv like crazy. it didnt bother me very much so i didnt care. well now its doing it when i go foward and not backwards. im assuming it's somthing with the cvt belt? any help would be great.

thanks,

 

a bike that age might have clutch issues. maybe take cover off to take a peak to see if parts are worn out before it explodes if its the clutch grinding its not good.

 

i just took it off yesterday but had no clue what to cheak for. so i put it back on. do you know what i should look at?

 

HEAH VINNY, HAVE YOU TRYED RUNNING IT WITH THE COVER OFF? MINE MADE NOISES TILL I ALIGNED IT. WATCH FOR ACTION OF THE PRIMARY+SECONDARY CLUTCHES WHEN YOU GO BACK+ FORTH. WATCH YOUR LEG+WEAR GOGGLES IT WOULD SUCK IF SOME THING FLEW OFF.
