Description
Mikuni N224.103 long-body pilot (slow) jet series for selected late TMX, OEM TMX36/TMX38 and OEM BSR CV carburetors.
Pilot jets control fuel delivery at idle and small throttle openings, making them critical for smooth starting, stable idle, and clean off-idle response. Select the required jet size from the available variants to suit your tuning needs.
This M4 x 0.7 jet features a 2.5 mm bleed tube and is not interchangeable with the visually similar VM28/486 series, which uses a smaller tip diameter. Always confirm jet dimensions and application before ordering.

Notice
Before You Order — Measure Your Jet First
Remove the jet from your carb and physically measure it. If it does not dimensionally match this listing, this is not the correct jet — do not buy it.
Buyer is solely responsible for confirming the correct jet size before purchasing. Do not rely on year/make/model fitment guides — they cannot be guaranteed 100% accurate.
All jet sales are final. No returns or exchanges — no exceptions.
