Keihin Red 30MM Length Velocity Stacks for FCR Carburetors
)
Product Description
Keihin 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 30mm which promotes good top end power with low restriction. Includes mounting hardware.
Lengths are available in 30mm or 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.
