Fuel Delivery:
Carbureted (e.g., Mikuni VM40) or Electronic Fuel Injection (EFI) depending on the specific model variant.
Recommended Fuel:
Premium unleaded gasoline (91 octane or higher is generally recommended for these high-performance engines).
Oil Change Interval Engine:
Typically every 100 hours or annually, but consult the manual for precise recommendations based on usage and oil type.
Belt Inspection Interval:
Inspect drive belt at 50-hour intervals or annually, replace as needed based on wear.
Spark Plug Replacement:
Refer to manual for specific intervals, often between 100-200 hours or based on condition.
Coolant Type:
