Tuning & Setup Notes

A progressive or dual carburetor swap changes the fuel curve of your engine, so plan on a proper jetting check and idle/mixture sync once the kit is installed — every engine's compression, cam, and exhaust combination is a little different. We recommend a mechanical fuel pump or a regulated low-pressure electric pump sized for carburetor use, fresh fuel line rated for ethanol-blended gas, and a check of your linkage geometry before first start-up.
