Fuel System
|
|
Carburetor Type:
|
Likely Mikuni or Keihin (e.g., Mikuni TM series, size dependent on model and year).
|
|
Fuel Type:
|
Unleaded gasoline, octane rating as specified in manual (typically 91 or higher).
|
|
Maintenance
|
|
Service Intervals
|
|
Oil Change Interval Typical:
|
Every 3,000-5,000 km or annually, check manual for specifics.
|
|
Air Filter Cleaning Interval:
|
Regularly, especially if used in dusty conditions. Check manual for specific mileage.
|
|
Valve Clearance Check Interval:
|
Typically every 6,000-10,000 km, refer to manual for exact intervals and procedures.
|
|
Fluid Specifications
|
|
Engine Oil Type:
|
Motorcycle-specific 4-stroke engine oil, SAE 10W-40 or 20W-50, API SG or higher, JASO MA certified. Consult manual for exact viscosity and specifications.
|
|
Coolant Type:
|
Permanent type antifreeze/coolant mixture (ethylene glycol-based) with distilled water. Refer to manual for ratio and specifications.
|
|
Brake Fluid Type:
|
DOT 4 hydraulic brake fluid.
|
|
Transmission Oil Type:
|
Separate transmission lubricant, consult manual for specific grade and capacity (often shared with engine oil on older single-crankcase designs, but best to verify).
|
|
Known Issues
|
|
Carburetor Icing:
|
Potential for carburetor icing in cold/humid conditions, particularly with constant velocity (CV) carburetors.
|
|
Valve Stem Seals:
|
Wear on valve stem seals can lead to increased oil consumption over time.
|
|
Electrical Connections:
|
Corrosion or loose connections in the electrical system can cause intermittent faults.
|
|
Suspension Seals:
|
Fork and shock seals can degrade over time, leading to leaks.
