Description
Genuine Mikuni VM28/486 pilot (slow) jet, engineered for precise idle and low-throttle fuel metering in selected Mikuni HSR, RS, TM (accelerator-pump) and HS carburetors.
This long-body, screw-in brass jet features an M4 x 0.7 thread, 28 mm overall length, and a 2.0 mm bleed-tube tip, ensuring a factory-correct fit and consistent fuel flow at low RPM. It is not interchangeable with the similarly sized Mikuni N224/103 series, which uses a larger 2.5 mm tip — installing the wrong series can cause serious tuning issues.
Compatible Carburetor Families:
- HSR42, HSR45, HSR48
- RS34, RS36, RS38, RS40
- TM33, TM36, TM40 (accelerator-pump equipped)
- HS40
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.
