Mikuni Pilot Jet for VM Round Slide Carburetors Jets

The Mikuni Pilot Jet (also called a slow jet or idle jet) is a precision-machined brass jet designed for Mikuni VM series round slide carburetors. It meters fuel in the idle and low-throttle range, so it directly affects idle quality, off-idle response, and low-speed fuel mixture.

Key Features:

• Made for Mikuni VM round slide carburetors
• Precision-calibrated fuel metering orifice for consistent, repeatable tuning
• Brass construction resists corrosion and wear
• Threaded design for straightforward installation and removal during jetting changes
• Available in multiple jet sizes, so you can fine-tune the low-speed mixture for your engine, exhaust, intake, and altitude

Mikuni has long been a leading carburetor manufacturer for motorcycles, ATVs, snowmobiles, and other powersports and small-engine applications. Fitting the correct pilot jet helps fix a rich or lean idle, hesitation, and poor throttle pickup. It is a common step when tuning after modifying the intake or exhaust. Choose the size that suits your setup from the available options.
