Description
Keihin 99101-393 small-round jets measure 8.0 mm long, with a 6.0 mm round head and M5 x 0.8 thread. This series meters main-circuit fuel in CV, CVK, VB, VD, VE and selected PD and PE carburetors.
In FCR and FCR-MX carburetors, it is a starter or main-air jet, not the primary fuel main jet. The standard FCR-MX37, FCR-MX39 and FCR-MX41 configuration uses size #200. Choose the size for the circuit you are servicing.
- FCR-MX exploded view reference: 29
- Diagram reference: Keihin FCR-MX exploded view, Ref 103.
- The diagram is for identification. Other illustrated parts are not included.
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.
