Carburetors are the most commonly rebuilt part on any motorcycle; however without some guidance it can be a difficult task. The Honda CL / CB350 family of bikes utilizes a CV or constant velocity carburetor that when properly rebuilt and adjusted provide ample performance, reliability and smooth drive ability. We have broken this guide into two parts each with a few sections and videos covering different aspects of dealing with the Honda CL / CB350 carbs.
Identification: Over the course of the Honda CL350 & CB350 (as well as SL350 K0) production (1968 - 1973) there were three different variations of the Keihin CV carburetor used on the bikes.

The Honda CL / CB350 carburetors will require a myriad of parts needed to properly perform a rebuild. We will review all the possible parts that you may need in the carbs to complete the task. Do note however every set of carburetors will be in different starting state when attempting a rebuild.

Each set of carburetors must be handled on a case by case basis depending on what is found during the tear down.
