Description

The Mikuni RS34-D21-K is a 34mm radial flat slide carburetor assembly designed for high-performance four-cylinder motorcycles. Its smoothbore induction tract and flat slide design enhance airflow to help deliver increased engine power.

This unit features an adjustable accelerator pump system for immediate throttle response, particularly at lower RPMs. It is 25 percent lighter than standard performance carburetors and uses widely available Mikuni jets.
