About Mikuni

Mikuni has supplied carburetors and fuel-system components to the motorcycle industry for decades, and its HSR series remains a common choice for carbureted Evolution and Twin Cam V-twins where a clean, tunable fuel curve matters more than electronics.

These Mikuni Bleed Pilot Jets in #15 size are specifically designed for VM28/486 carburetors, sold in a convenient 4-pack. They are crucial for controlling fuel delivery at idle and low-speed throttle positions, ensuring smooth running and reliable cold starts on V-twin engines. Proper pilot jetting is key to a well-tuned carburetor.

Essential for Carburetor Tuning

Pilot jets are a critical component in any carbureted V-twin setup, impacting everything from fuel economy to overall rideability. If your bike experiences hesitation off-idle or struggles with inconsistent low-end performance, a change in pilot jet size may be necessary. While these jets are a direct fit for VM28/486 carbs, remember that comprehensive carburetor tuning or a dyno session might be needed to fully dial in your fuel system after any jetting changes.
