I recently sunk my 08 650 IRS I flooded my drive belt caseing.. I drained the caseing. It drove and pulled fine. I dont notice any slippage what so ever. But I do have a kind of grinding noise from the caseing after it starts pulling. Any idea what this noise could be. I thought maybe the belt stretched or something. I dont want to damage the primary gear. Any help would be appreciated.

 

Take your CVT cover off and clean it with soap and water.....then check for small rocky pebbles logged into the primary system or belt/pulley.
