Keihin Blue 50MM Length Velocity Stacks for FCR Carburetors
Product Description
Keihin Blue velocity stacks improve the air flow into the carburetors by smoothing small eddy currents that develop near the intake bells of carburetors, especially during high intake velocity conditions. This not only increases horsepower by improving combustion, but also increases throttle response and fuel atomization. Fits Keihin FCR35-41 flat slide carburetors. The length of this velocity stack is 50mm which promotes better torque and mid-range response. Includes mounting hardware.
Lengths are available in 30mm and 50mm. Choose your length depending upon your clearances and tuning requirements. Shorter lengths relate to less restriction and higher RPM power whereas the longer lengths smooth flow more and provide higher low RPM torque characteristics. Velocity stacks are sold each. Blue stacks are available for FCR28-33 and FCR35-41 carburetors. Make your selection now before adding to your cart.
