~~$29.90~~ $28.95

The Keihin Main Jet #180 Hex is a direct-replacement carburetor jet for Keihin-carburetted motorcycles. The main jet governs fuel delivery at mid-to-high throttle openings and is a routine service item when re-jetting for altitude, intake, or exhaust modifications.

The hex head design allows removal and installation with a standard hex socket or wrench, reducing the risk of damage compared to slotted-head alternatives. Sold as a pack of four, this listing suits workshop stock, jetting experiments, or keeping a set of spares on hand.

Install and remove using a correctly sized hex socket to avoid rounding the head — do not use pliers or flat-blade screwdrivers.
Tighten to snug-firm only; over-tightening can strip the carburetor body threads or crack the jet.
Before installation, hold the jet up to light and confirm the orifice is clear and free of debris.
Clean blocked jets by soaking in fresh carburetor cleaner and blowing through with compressed air — never use wire or drill bits, which will alter the orifice size.
Inspect the jet seating surface and the mating carburetor bore for damage or debris before fitting a replacement jet.
Store unused jets in a sealed bag or container to prevent contamination and corrosion.
When jetting for altitude or modifications, change one jet size at a time and test ride before making further adjustments.
