Description
A properly sized pilot jet is critical for smooth idle quality, responsive throttle response at low RPMs, and consistent cold-start performance across varying atmospheric conditions. If your Mikuni carb is running rich or lean at idle, or hesitating off-throttle, a pilot jet change is often the first and most cost-effective tuning solution. This 4-pack gives you the flexibility to dial in the exact air-fuel ratio your engine demands without repeated ordering.
