Just put a new belt on my sled tonight.....sled ran and moved fine on to the trailer....later took it out to go for a blast....and after a lap around the house it was singin....LOUD. Goes away after I blast around then seemed to go away......seems like its rubbing on the primary closest to the motor just a tad.....My other belt was nearly smoked but I got a solid 65 miles out of it (3000 miles on the sled) then she started to come apart. I am wonderin if it needs to break in? I haven't ever heard of this....wonderin if somehow my clutches came out of line? Help!
