TUNING RACE – for professionals
This product fits on almost all products Product description
The KEIHIN PWM series of flat-slide carburettors represent the absolute high-end of the market. Extremely high quality and produced with minimal manufacturing tolerances, these carburettors are currently peerless in their segment. This level of quality convinced the engineers at YAMAHA for example, to choose them as their factory carburettor supplier. Usually, the individual stages of carburation are clearly defined which facilitates precise adjustment. The KEIHIN PWM carburettors provide an excellent throttle response and deliver a solid and reliable performance across the whole rev-range of the motor. These qualities not only makes them excellent for racing purposes, but also irreplaceable in high-performing street machines pushing out more than 30PS. We have these powerful KEIHIN carburettors available in the web-shop in sizes ranging from 28-41mm. The PWK 35 Airstriker stands out as a perfect complement to RD350 based reed-valve set ups. Their PWK 41 Pro is an extensively modified version with a CNC machined air-intake funnel. The PWM versions are the newest and most powerful range of KEIHIN carburettors. Conclusion: THE high-end tuning carburettors! Often imitated, but never equalled.
These carburettors are ideally complemented when combined with the MMW manifolds (#408121JO). The DELL’ORTO jetting kits (e.g. main jet: #KODB0010 & pilot jet: #KODC0010) are extremely helpful while adjusting the jetting of these excellent carburettors!
