Good To Know

Q: Will this carburetor need jetting changes after installation? A: It is set up as a stock replacement, but altitude, temperature, and exhaust changes can affect jetting, so fine-tuning may be needed for best running.

Q: Can I reuse my original intake boot and cables? A: In most cases the factory intake boot, throttle cables, and fuel line connect to this replacement carburetor without modification, but check your machine before ordering.

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