Good To Know

Q: Will this carburetor bolt straight onto my stock Sportster? A: It is built as a direct replacement for the 40mm CV40 and cross-references 27490-04, so it mounts to factory intake and throttle connections. Verify your model and year before ordering.

Q: Do I need to rejet after installing it? A: Jetting may need adjustment based on altitude, exhaust, and intake changes. Start with stock settings and tune from there for best running.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
