Designed as a direct-fit performance upgrade, this kit delivers dramatically improved throttle response, smoother power delivery, and up to a 25% increase in horsepower—all without the common issues of flat spots or hesitation.

Kit Includes:

• 1x Set of Mikuni RS34 flatslide carburetors

• 4x Engine mount stub flanges
