Keihin PWK39 Universal Carburettor

KEIHIN PWK39 Carburetor – a staple in the paddocks, the PWK39 is aimed at riders seeking precise tuning and immediate throttle response. Designed for motocross competition, this carburetor is widely favored on factory machines for its performance-oriented design and ease of adjustment.

• Semi-flat chromed slide (D): better response and optimized flow at high RPMs.
• Engineered bore sizes to provide an air passage suited to the needs of powerful engines.
• Simplified adjustment: jets and carburetion parts available to refine tuning according to altitude and fuel.
• Quad Vents: reduces the risk of air being sucked in after jumps by limiting clogging of ventilation ducts.
• PWK Air Strikers: directs air to the main jet for better signal and sharper throttle response.

The PWK39 fits perfectly into enduro/cross preparation projects and on any motorcycle requiring high-performance carburetion. Installation and tuning should be carried out following engine recommendations: adjust the jets and synchronization according to the setup and usage conditions to achieve clean and safe operation.
