Specs At A Glance

Good To Know

Q: How do I know when the drive belt needs replacing? A: Signs include glazing, cracks, frayed edges, missing cogs, or a belt riding too low in the secondary clutch. A worn belt causes sluggish takeoff and reduced top speed.

Q: Is belt replacement something I can do at home? A: Yes, it is a common DIY task that involves opening the secondary clutch and rolling the new belt into position. Verify deflection and alignment afterward for proper operation.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
