🔧 Maintenance
Service Intervals
Oil Change Engine:
2-stroke engines typically do not have oil changes in the same way as 4-strokes. Autolube oil reservoir needs refilling. Manual will specify type: Yamaha 'L-Type' Premium 2M Oil or equivalent.
Spark Plug Replacement:
Recommended every 1,000-1,500 miles or annually. Manual will specify exact intervals and part numbers (e.g., NGK BR9ES or BR9EYA).
Clutch Inspection:
Inspect primary and secondary clutches at 500-mile intervals or annually. Belt inspection at 100 miles initially, then every 1000 miles.
Track Tension Adjustment:
Check and adjust every 500 miles. Manual will specify correct tension measurement and procedure.
Chain Case Lubrication:
Check oil level every 500 miles. Change oil annually or every 1000 miles. Manual will specify lubricant type and capacity (e.g., Yamaha Gear Oil or equivalent).
Fluid Specifications
Engine Oil:
Yamaha 'L-Type' Premium 2M Oil (or equivalent API-TC certified 2-stroke oil for pre-mix applications, though Autolube is standard).
Coolant:
50/50 mixture of ethylene glycol antifreeze and distilled water. Manual will specify exact type and color.
Brake Fluid:
DOT 3 or DOT 4 hydraulic brake fluid (manual will specify exact type).
Chain Case Oil:
Yamaha Gear Oil (GL-4) or equivalent SAE 80W-90 gear oil. Manual will specify exact viscosity and quantity.
Known Issues
Carburetor Fouling:
Can occur with improper fuel mixture or stale fuel, leading to poor idling and performance. Manual provides cleaning and adjustment procedures.
Drive Belt Wear:
Regular inspection and replacement of the CVT belt is crucial to prevent sudden failure and damage to clutches. Manual details inspection criteria and replacement procedure.
Suspension Wear:
Over time, bushings and bearings in the suspension can wear, leading to imprecise handling. Manual outlines inspection and replacement of wear items.
