Description
Carburetor tuning demands precision—even small variations in jet sizing throw off your air-fuel ratio and cost you performance on the track or dyno. These EBC Keihin-style jets are brass-constructed and flow-calibrated to exacting tolerances, giving you the accuracy you need to dial in your mixture without guesswork. Whether you’re chasing optimal peak power or smooth throttle response across the RPM band, having the right jet size in hand eliminates trial-and-error tuning.
