Depth Of Coverage:
Professional workshop level, covering everything from routine maintenance to complete engine rebuilds and advanced electrical diagnostics.
Illustration Quality:
High-quality pictures and diagrams supporting procedural steps.
Engine Type:
2-stroke, single-cylinder (for 200, 250, 300cc variants)
Bore Stroke Typical:
Typical bore/stroke varies by displacement (e.g., 200cc ~62.5x65mm, 250cc ~66.4x72mm, 300cc ~72x72mm - *exact specs would be in the manual*).
Power Output Typical:
Power figures vary by displacement and tuning, generally in the range of 30-50+ HP (*exact specs in manual*).
Carburetor Type Likely:
Likely Dell'Orto VHSH/VHSB or Keihin PWK series carburetor.
Fuel Type Recommendation:
Requires high-octane gasoline mixed with specific 2-stroke oil ratio (*manual will specify ratio and oil type*).
Cooling Method:
Liquid-cooled, via radiator and fan (if equipped).
Oil Change Interval:
Intervals for engine oil and gearbox oil changes are detailed in the manual, typically based on operating hours or mileage.
Spark Plug Replacement:
Recommended spark plug inspection and replacement intervals will be specified.
Coolant Type:
Specific coolant mixture (e.g., 50/50 ethylene glycol based) and capacity will be listed.
Brake Fluid Type:
DOT 4 or DOT 5.1 hydraulic brake fluid specification is standard, to be confirmed in the manual.
Two Stroke Oil Type:
Manual will specify type and viscosity of 2-stroke engine oil (e.g., JASO FD compliant, semi-synthetic or fully synthetic).
Common Wear Items:
Common wear items in this era of enduro bikes include clutch plates, piston rings, fork seals, and wheel bearings.
Carburetor Tuning Sensitivity:
2-stroke carburetors can be sensitive to altitude and temperature changes, requiring periodic jetting adjustments.
