Adjusting the valve clearance on a vintage Japanese bike goes a lot faster if the necessary shims are on-hand. Our 25mm valve shims will fit many classic Honda and Yamaha motorcycles. Individual 25mm shims are available in sizes from 2.30mm to 3.10mm, and they are separated in .05mm increments. We also stock the Honda valve shim changing tool, which eliminates a headache only CB750, CB900 and CBX owners can fully appreciate.
Our 25mm shims fit the Honda CB750, CB1000, CBX and CB1100, as well as the Yamaha FJ1100, XVZ1300, XJ600 and more. These 25mm shims are also available as a complete kit (two shims of each size).
