Performance

Performance Estimates:

Horsepower typically ranged from 40-55 HP, depending on the specific engine tune and year. Torque figures would be commensurate with a mid-size, naturally aspirated two-stroke engine of this displacement.

Engine Type:

Two-stroke, liquid-cooled, parallel twin-cylinder.

Fuel System

Fuel System:

Carbureted. Likely dual Mikuni VM series carburetors, sized appropriately for the 480cc displacement and engine characteristics. Fuel type would be pre-mix or oil injection depending on the specific model year and variant.

Carburetor Identification:

Specific carburetor models (e.g., Mikuni VM34SS or similar) and their jetting specifications will be listed.
