Your vintage Kawasaki’s petcock is the fuel’s gateway to your carbs, and it must be operating smoothly for you to get the most out of your KZ1000. Worn springs and diaphragms can allow too much fuel through and flood the carburetor float bowls. A Pingel petcock is a great solution for your vintage Japanese motorcycle restoration. Pingel is the first name in aftermarket petcocks and fuel valves. We have single-outlet and double-outlet Pingel petcocks, brass Pingel petcocks and Pingel petcock adapter plates. Z1 also stocks KZ1000 petcock kits, CB750 petcock kits and Suzuki petcock kits. We also have diaphragms and petcock kits for most other vintage performance Japanese motorcycles.
