Carburetor Type:
Mikuni VM Series (e.g., VM28SS or similar)
Fuel Type:
Unleaded gasoline (91 octane or higher recommended)
Fuel Mixture:
Pre-mix (Gasoline/2-stroke oil mixture, typically 40:1 or 50:1 depending on oil and conditions)
Engine Oil Change:
Every 10-15 hours of operation or annually, using recommended 2-stroke oil and a pre-mix ratio (refer to manual for precise specification).
Air Filter Cleaning:
After every few rides, or more frequently in dusty conditions. Wash and re-oil with appropriate filter treatment.
Chain Lubrication Adjustment:
Lubricate chain every 200-300 miles, or more often under wet/dirty conditions. Adjust tension every 500 miles or as needed.
Spark Plug Inspection:
Inspect and clean/gap every 10-20 hours. Replace as needed.
Brake Fluid Flush:
Every 12 months to ensure optimal braking performance.
Engine Oil Type:
High-quality 2-stroke motorcycle oil, JASO FD or equivalent (e.g., Motul 800, Castrol TTS).
Transmission Oil Type:
SAE 10W-30 or 10W-40 API SG, Jaso MA motorcycle gear oil.
Coolant Type:
