Optimizing the pilot circuit is essential for a well-tuned carbureted V-twin, especially when you're looking for crisp, immediate throttle response. These Mikuni Bleed Pilot Jets in size #22.5 are designed to provide accurate fuel delivery at idle and through the initial stages of throttle opening in VM28/486 carburetors. They feature a small air bleed hole that helps lean out the mixture slightly, which can improve cold starting and overall idle characteristics compared to standard pilot jets.
