7M valve shim donors
If you ever struggle to find cheap or variety of shim thicknesses a little searching turns up some places you can look for shims. Most valuable is the fact that honda has shims thinner and thicker than toyota offers.
* Some common compatible valve shim donors: 16-valve 4A-G(Z)(E)
* 4A-F(E)
* 7A-FE
* 7M-G(T)E
* 3S-G(T)E
* 5S-FE (pre-'93)
SOB shims
25mm diameter Used in Honda ('79--'83 4-cylinder CB750, 900, 1000, and 1100 series engines,
and 1050 CBX 6-cylinder engines, and others), Yamaha (V-Max, and the FJ1100/1200 series),
Triumph 3- and 4-cylinder liquid-cooled motorcycle engines, and older Toyota car engines.
HotCams makes shim kits but i found they dont carry the larg sizes. Honda dealer local to me had all but 1 shim i needed and all were like aprox $5 each as compared to toyota pricing of $8+ (canadian) im not sure what the toyota shims are but i remember people saying they are arround 10 bux each.
So simply raid your local pick a part for your normal range of shims and order any thicker ones you might need.
Thickness, Honda Part No. Toyota Part No. *
