I have a 96 V-max 600 with 3300 miles and have had ZERO problems with until this year, the track has started sounding like it is slipping, but only in deep snow under hard accelleration, like when the track wants to spin in snow. It does not happen on hard pack or ice. I have tried to tighten the track and it seemed to help a little, but don't want to over tighten it. Any suggestions? Thanks in advance!
