Okay guys i have kind of a dum question. Today i took my sled a 96 zr580 efi with the ETT tunnel for a first ride and was the first person on the trails. There was 4 or 5 inchs of heavy snow and when i would get on the gas hard going down the trail there was this kind of racheting sound coming from down by the track. Looking back at where this was happening there was some dirty colored snow so i am thinking that the track was spining down to the dirt and the sound was the track spin hitting the dirt. I don't think that the track is jumping the cogs because the track looks in adjustment.
