Description
Carburetor jetting is fundamental to engine tuning—too rich and you waste fuel while fouling plugs, too lean and you risk detonation and seized rings. These EBC Mikuni-style jets are brass castings flow-calibrated to exacting tolerances, ensuring your fuel delivery matches your engine’s air intake precisely. Whether you’re chasing peak horsepower on the dyno or dialing in a freshly ported head, accurate jetting eliminates guesswork and delivers repeatable, predictable results.
The HJ340-4 four-pack gives you flexibility to experiment across jet sizes without the downtime of sourcing individual replacements. These are high-quality aftermarket jets designed to Mikuni specifications—not OEM originals, but precision-engineered alternatives that perform equally well at a fraction of the cost.
