SK is OER carburetor. Fits the standard DCOE manifolds. Looks like a Mikuni, but uses Weber DCOE tuning parts. Has two advantages: externally adjustable float level and externally adjustable accelerator pump stroke. Only available in racing sizes starting at 44mm (too big for most A-series except racing engines).
