The PWK flat slider series belongs to the absolute top class of carburetors. Extremely high quality and manufactured with the lowest level of manufacturing tolerance are currently second to none in terms of quality and performance. YAMAHA also decided as an original equipment manufacturer in the PWK carburetor industry. The individual carburettor fields can generally be delineated very easily and also set up with high precision. PWK therefore responds quickly to throttle setting and provides solid performance across the entire rev range. This not only means it is the first choice in the motor racing area, it is also indispensable for high performance street engines tuned either side of the 30 PS mark. We stock high performance PWK carburetors in sizes 28-41mm. Above all else, the PWK 35 Airstriker is the ideal supplement for rod valve systems on an RD350 base. The PWK 41 Pro is a reworked version processed with a CNC-turn air intake system. carburetors all feature a power jet that also reliably feeds the engine with sufficient mix at full throttle, even if a relatively lean jet is chosen. Indispensable on the racing circuit. Conclusion: High End carburetor tuning. Often copied but never equaled. SIP-TIP: An optimal add-on to the MMW2 intake manifold (n. 408121J0). Dellorto jet kits (e.g. main jet part without KODB0010 and idle jet part without KODC0010) also make tuning easier in this context!
