Engine Specifications
|
Primary Engine
|
Engine Type:
|
Single-cylinder, four-stroke (specific displacement varies by MadAss model variant, commonly 125cc, 150cc, 200cc, and 250cc, often based on Honda CG derived engines).
|
Bore X Stroke:
|
Varies by engine size; specific dimensions provided in manual for each variant.
|
Compression Ratio:
|
Varies by engine size; specific ratios provided in manual.
|
Performance
|
Horsepower Torque Range:
|
Varies by displacement; typically 8-20 HP and 10-25 Nm torque. Specific data requires model year and engine variant.
|
Fuel System
|
Fuel System Type:
|
Carburetor (specific models vary, e.g., Keihin or Mikuni derivatives), fuel injection on later or specific variants.
|
Engine Codes
|
Common Engine Codes:
|
Often derived from Honda CG series engines (e.g., CG125, CG150, CG200). Specific codes will be detailed within the manual for each variant.
|
Cooling System
|
Cooling System:
|
Air-cooled, sometimes with oil cooler on larger displacement models.
|
Ignition System
|
Ignition System:
|
CDI (Capacitor Discharge Ignition) or Electronic Ignition.
|
Maintenance
|
Service Intervals
|
Oil Change Interval:
|
Typically every 3,000-5,000 km or 6-12 months, whichever comes first, based on riding conditions. Manual will specify precise interval.
|
Valve Adjustment Interval:
|
Usually around 6,000-10,000 km. Detailed procedure and clearances in manual.
|
Chain Lubrication Adjustment:
|
Every 500-1000 km, or after riding in wet conditions. Manual provides adjustment specifications.
|
Fluid Specifications
|
Engine Oil Specification:
|
SAE 10W-40 or 20W-50, API SG or higher, JASO MA approved motorcycle oil.
|
Brake Fluid Specification:
|
DOT 3 or DOT 4 (check specific model variant, manual will clarify).
|
Fork Oil Specification:
|
SAE 10W or 15W fork oil (quantity specified per fork leg).
|
Coolant Specification:
|
Not applicable for air-cooled models. If oil-cooled, the engine oil serves this function.
|
Known Issues
|
Common Wear Items:
|
Tires, brake pads, chain and sprockets, spark plugs, air filter, clutch plates (under heavy use).
|
Potential Electrical Issues:
|
Loose connections, stator or rectifier issues on some older models. Wiring diagrams are critical.
|
Carburetor Tuning Challenges:
|
Can require fine-tuning for optimal performance, especially with modifications or altitude changes. Manual covers tuning procedures.
