This is a demonstration of how I replaced an aftermarket fuel filter in a 1995 Kawasaki Vulcan VN800A. When doing this task I discovered the petcock was not closing completely, resulting in a constant slow internal leak of fuel to the carburetor. Fortunately the carb bowl float had not allowed fuel to leak past and contaminate oil or hydrolock the engine.
This repair shows how one can solve this problem without necessarily replacing all the seals or replacing the entire petcock.
The design features and vulnerabilities of motorcycle petcocks and fuel delivery are discussed.
This is an amateur demonstration, offered for free and in good faith but with no guarantees as to accuracy or safety. Before attempting repair of your bike, you need to decide whether you are willing to accept risk. Never rely on a single source for critical information. Any misadventure you encounter if you decide to accept the risks of DIY repair of your bike is your responsibility.
