The KEIHIN PWK33 carburetor is a benchmark for riders who demand precise tuning and immediate throttle response. A descendant of the dominant motocross models, the PWK33 focuses on an attack-oriented design: improved acceleration response, optimized flow at high RPMs, and the ability to fine-tune the carburetion according to the terrain and engine.
- Semi-flat (D profile) chrome slide: offers better response and increased airflow at high RPMs.
- Calibrated intake passages: sized to prioritize performance and efficiency at high RPMs.
- Simplified jet adjustment: jetting parts available to adapt the carburetion.
- Quad Vents: prevent stuttering after jumps by reducing clogging of the ventilation passages.
- PWK Air Strikers: channel air to the main jet to improve the "signal" and responsiveness upon throttle opening.
Versatile and performance-oriented, the PWK33 is aimed at riders from all backgrounds looking for a reliable carburetor to tune for track or enduro use. For optimal operation, ensure a jetting adjustment suited to your model and usage conditions.
