Keihin PWM Carburetor

Designed for high-RPM two-stroke racing engines, PWM is a 38mm, short body carburetor aimed squarely at motorcycle road-racing, flat track, and shifter kart applications where maximum peak power output is the key to lowering lap times.

PWM Features and Benefits:

• Shorter overall length for better top end power
• New throttle slide design for improved signal at the main nozzle
• Easy access to both the main and slow jets through the float bowl plug
• Single control for both idle speed and enrichener settings.
• Easy jetting with a wide selection of jetting parts available
