The flat cursor series Keihin Pwk belongs to the absolute high end of the carburetors. Extremely high quality and produced with the minimum level of production tolerance are currently second to anyone in terms of quality and performance. Yamaha also decided Keihin as a manufacturer of original equipment in the Pwk carburettor sector. The individual carburetor fields can generally be outlined very easily and also established with high precision. Keihin Pwk then quickly responds to the adjustment of the butterfly valve and provides a solid performance on the entire range of regimes. This not only means that it is the first choice in the car racing area, it is also essential for high road engines tuned performances both sides of the 30 PS sign. We store the high charcoal Keihin Pwk carburettor in size 28-41mm. Above everything else, the PWK 35 Airstriker is the ideal supplement for rod valves systems on an RD350 base. The PWK 41 PRO is a reworked version processed with a CNC-Girare air suction system. The Keihin carburetors are all equipped with a power jet that also reliably feeds the engine with sufficient mix with full gas, even if a relatively thin jet is chosen. Indispensable on the racing circuit. Conclusion: High End developed by the carburettor. Often copied but never equal. SIP-TIP: an additional optimal to the MMW2 suction collector (n 408121J0). Dell Aorto Jet Kit (for example, the main part of the jet without Kodb0010 and inactive part of the jet without Kodc0010) also make the easiest development in this context!
