The Mikuni Main Jet #270 Hex is a replacement fuel-metering jet designed for use in Mikuni carburettors. The hex-head profile allows for clean installation and removal with a standard hex tool or socket, reducing the risk of damage during jetting changes.

Supplied in a pack of four, these jets suit riders and mechanics who tune carburettor fuelling to account for altitude, temperature, engine modifications, or exhaust upgrades. Having multiple jets on hand simplifies back-to-back comparisons without waiting on individual replacements.

Confirm jet size compatibility with your specific carburettor model and current tune before installation.
Use the correct hex tool or socket — avoid pliers or adjustable spanners, which can round the hex head.
Tighten to snug: hand-tight plus a fraction of a turn with a tool; do not overtighten, as brass threads are easily damaged.
Inspect the jet orifice for blockage before and after use; clean with carburettor cleaner and compressed air if required.
Do not probe the orifice with wire or metal picks, which can enlarge or distort it and alter fuel metering.
Store unused jets in a labelled, sealed container to prevent contamination and accidental mixing of sizes.
When jetting for altitude or temperature changes, adjust one size at a time and test before making further changes.
