Paper Type:
Durable, often coated paper to resist grease and moisture common in a repair setting.
Engine Type:
Liquid-cooled, 2-stroke, reed valve induction
Bore X Stroke:
64 mm x 54 mm (per cylinder)
Displacement:
347 cc (21.1 cu. in.)
Compression Ratio:
7.1:1 (standard, actual may vary with porting/tuning)
Carburetor:
Dual Mikuni VM26SS
Horsepower Estimate:
Approximately 45-50 HP (stock, actual may vary)
Torque Estimate:
Not officially published but significant low-end and mid-range torque for its class.
Fuel Type:
Unleaded gasoline (minimum 87 octane recommended, higher octane for modified engines)
Fuel Oil Mix Ratio:
50:1 (Yamalube 2-stroke oil or equivalent API-TC, JASO FD certified oil)
Oil Change:
Transmission oil should be checked regularly and changed per manual recommendations (typically every 100-200 operating hours or annually).
Spark Plug:
Inspection and cleaning/replacement intervals are critical for optimal 2-stroke performance; typically checked every few rides and replaced as needed.
Air Filter:
Frequent cleaning and inspection, especially in dusty conditions, is crucial for engine longevity.
Chain Lubrication And Adjustment:
Regular lubrication and tension checks are vital for drivetrain performance and longevity.
Engine Oil Mix:
Yamalube 2-stroke (TC-W3 rated for oil injection systems, though pre-mix is common for Banshees).
Coolant:
Ethylene glycol-based coolant (50/50 mix with distilled water) for liquid-cooled engines.
Carburetor Fouling:
Common in 2-strokes due to fuel/oil mix and potential for stale fuel. Regular cleaning is recommended.
Top End Wear:
High-performance 2-strokes can experience faster wear on pistons and cylinders if not properly maintained, particularly with aggressive use.
Clutch Wear:
Aggressive riding can lead to premature clutch wear.
Electrical Connections:
Corrosion or loose connections can cause intermittent electrical issues.
Yamaha Offroad:
Yamaha has a long and storied history in off-road motorsports, dating back to the 1960s, known for performance and innovation.
