Was out for a ride yesterday and started to hear a noise from clutch DD area. At first when I would let off the gas it sounded like a light clacking noise. I could barely hear it. Then all of a sudden noise got louder. Actually there was a loud snapping noise when i let off the gas and then after that the clacking noise got more pronounced. Sled still ran good other than making noise. It is still under warrenty and will be taking to dealer. But am curious If any one has any ideas.
