With each carb diaphragm we sell, we will email you, the customer, a PDF instruction sheet on how to install them. Should you have more questions this video shows the installation process.
The diaphragms found in the Keihin CV (Constant Velocity) carburetors used on the Honda CB350 and CB360 family of motorcycles are often found torn, melted, or with pinholes in them. Lucky replacement diaphragms are available and we show you how to install the new diaphragms on the original carburetor slides. While similar in design, the diameter of the slides is different between the CB350 and CB360 families of bikes. The installation process is easy and takes only a few minutes with basic hand tools.
