Fuel Type:
Unleaded gasoline, Octane rating to be specified in manual.
Ignition Type:
Electronic Ignition (CDI - Capacitor Discharge Ignition) or potentially breaker-point ignition on earliest versions, but CDI became standard for this era.
Oil Change Interval:
Recommended every 2,000-3,000 miles or 6 months, refer to manual for exact interval.
Valve Check Interval:
Typically every 6,000-10,000 miles. Manual will specify precise interval and procedure.
Chain Maintenance:
Regular cleaning, lubrication, and tension adjustment (every 500-1000 miles or as needed).
Engine Oil Type:
