Mikuni Carburetor Pilot Jet

The Mikuni carburetor pilot jet (also called a slow jet or idle jet) is a precision-machined brass metering jet. It controls the fuel flow in the idle and low-throttle range of a Mikuni carburetor. Fuel delivery at idle, off-idle and light throttle depends on this small part, so it affects throttle response and overall tuning.

Key Features:

• Precision-calibrated orifice for consistent, repeatable low-speed fuel metering
• Brass construction resists corrosion and wear
• Lets you fine-tune idle quality and low-throttle response when jetting for changes in altitude, temperature, exhaust or intake
• Direct replacement for a worn, damaged or clogged pilot jet
• Made by Mikuni, a long-established maker of carburetors for motorcycles, ATVs, snowmobiles, personal watercraft and other powersports and small-engine applications

Choose the jet size that matches your carburetor model and tuning needs. Fitting the correct pilot jet helps the engine start easily, idle smoothly and transition cleanly off idle. Clean the jet regularly, because a partly blocked pilot jet can cause hard starting, poor idle and hesitation.
