When vintage Japanese carburetor jets become clogged with debris, a simple cleaning should restore their proper operation. However, when the layer of varnish becomes baked on, or they become pitted or cracked, they must be renewed. Z1 is a great source for vintage Mikuni carburetor main jets, pilot jets and jet needle shims for the KZ1000, CB750, and Suzuki and Yamaha 2-stroke engines. We also stock Keihin main jets, pilot jets and jet needle shims for horizontal and downdraft carburetors on vintage Japanese motorcycles.
