Initial Breakin Service:
Refer to the owner's manual for specific break-in procedures, typically involving varied throttle usage and avoiding prolonged idling or full throttle. Check clutches and check fasteners after first few rides.
Chaincase Oil Change:
Annually or every 1,000 miles (verify specific interval in manual).
Spark Plug Replacement:
As needed, typically every 1,000-2,000 miles or if fouled. Refer to manual for recommended plugs (e.g., NGK BR9ES or similar).
Drive Belt Inspection:
Inspect at every ride for wear, cracks, or fraying. Replace as needed, recommended replacement interval is typically 2,000-3,000 miles, but can vary.
Coolant:
Ethylene glycol-based antifreeze (50/50 mix with distilled water) for fan-cooled engines. Check manual for specific type if liquid-cooled.
Primary Clutch Wear:
Wear on the primary clutch sheave or roller buttons can affect performance and belt life. Regular inspection and lubrication are key.
Suspension Bushings:
Wear in A-arm bushings and ball joints can lead to steering looseness and uneven tire wear. Regular greasing is advised.
Carburetor Tuning:
Due to altitude and temperature variations, carburetor jetting and adjustment may be necessary for optimal performance. The manual provides guidance on this.
Grease Points:
Steering post, suspension pivots, jackshaft bearings, driveshaft bearings. Refer to manual for specific locations and grease type (e.g., Moly grease).
Polarishistory:
