Maintenance
|
Service Intervals
|
Oil Change Interval:
|
Typically every 100-150 engine hours or annually. Check for specific recommendations in the manual.
|
Spark Plug Replacement:
|
Recommended every 100-150 engine hours or as needed based on inspection. Use correct NGK or equivalent plugs.
|
Track Tension Adjustment:
|
Check and adjust as needed every few rides, or after initial break-in. Correct tension is critical for track and bearing life.

|
Coolant Type:
|
Ethylene glycol-based antifreeze (e.g., Yamalube Coolant or a 50/50 mix of a quality automotive antifreeze and distilled water). Check manual for specific type and capacity.
|
Brake Fluid Type:
|
DOT 3 or DOT 4 hydraulic brake fluid. Ensure clean system and proper bleeding.
|
Known Issues
|
Carburetor Icing:
|
Common in cold, humid conditions. May require adjusting jetting or using anti-icing additives. Manual will detail troubleshooting.
|
Clutch Belt Wear:
|
Drive belts can wear out or break if overloaded, misaligned, or if the clutches are not functioning correctly. Manual provides inspection guidelines.
|
Suspension Bushings And Bearings:
|
Wear in bushings, shocks, and bogey wheel bearings can affect ride quality and handling. Manual details inspection and replacement procedures.
