I03-0102-S/N Needle/seat Kit Mikuni 42/45

This needle and seat kit from Drag Specialties is a precision-engineered replacement for Mikuni HSR42 and HSR45 carburetors. The kit includes the fuel inlet needle and the corresponding seat, which are the primary components responsible for regulating fuel levels within the carburetor float bowl. Over time, these parts can wear or become contaminated, leading to flooding or fuel starvation. Replacing them with this high-quality set restores accurate fuel metering and prevents leaks. Designed to meet or exceed original equipment specifications, this kit is essential for any comprehensive carburetor rebuild. This product is sold as a set and ensures reliable fuel system operation.
