Initial Break In:
Typically 500 miles or 10 hours, involving gradual speed increases and avoiding sustained high RPMs. Consult manual for specific break-in procedure.
Oil Change Chaincase:
Every 1,000 miles or annually. Use Polaris synthetic chaincase lubricant or equivalent.
Spark Plug Replacement:
Recommended every 1,000-2,000 miles, or as wear dictates. NGK BR9ECS or equivalent is a common recommendation.
Drive Belt Inspection:
Inspect at 500 miles and every 1,000 miles thereafter for wear, cracks, and edge damage. Replace as needed.
Suspension Lubrication:
Grease all suspension pivot points and linkage every 500 miles or annually.
