KEIHIN JET – Manufacturer's ref: 99101-124-140

Replacement part intended for fuel systems, this jet from Keihin is designed for riders who are concerned about the proper adjustment of their carburetor. Designed to regulate the flow of gasoline, it plays a direct role in calibrating the air/fuel mixture and is one of the key elements during an adjustment, a revision, or a recommissioning.

Why replace it:

• Allows for adjusting the air/fuel mixture according to the engine's needs (idle, full throttle, transition).
• Used during maintenance of the bowl, needle replacement, or to correct an inappropriate richness.
• Original Keihin part: optimal compatibility with the brand's carburetors.

Usage tips and compatibility:

• Before ordering, check the original reference of your jet and the type (main, idle, needle) corresponding to your carburetor.
• Replacement is done during the disassembly of the bowl cover — a common intervention in workshops or with a tuner.
• If in doubt about the proper calibration, consult a professional to avoid a mixture that is too lean or too rich.
