SC2 SmartCarbs are available in 36, 38, and 40mm sizes and are designed to replace conventional carburetors in 2-stroke applications from 125cc up to 500cc or more. They are a direct fit in applications originally equipped with Keihin PE, PJ, PWK and Mikuni VM and TM series carburetors of similar sizes. 38mm size depicted.
