How do you adjust the drive belt on a bombardier outlander ATV?

Drive belts are not adjusted on a BRP Outlander, or any of the Bombardier atv's for that matter. If your machine is creeping in gear and hard to shift from reverse to forward and back it is most likely the one way bearing(the engine braking mechanism on the primary clutch) that is dirty and needs to be cleaned and lubricated with isoflex grease,(grease skidoo uses to lubricate the outside pto and mag bearing on the 2 stroke crankshafts) Its expensive grease but it works very well.
