I was riding in pretty deep snow wirh my new to me bike for about an hour and all of a sudden I realize no power is going to the track. Jumped off the bike and didn't smell or notice anything outwardly wrong. Engine was running great, but when in gear you would rev it and nothing would happen unless you had it at like 10k rpm and then it would only move very little. Little info I'm a big guy, also there was about 15-18" of fresh. It has a rekluse core exp 3.0 clutch on it. There was no clutch smell or fade, It was an instant change
