You figure out which sizes are needed through trial-and-error, basically. With shims installed, you measure the valve lash and see where it is. Tight valves need smaller shims. Loose valves need bigger shims. There's no "this size shim for this valve" guide--every bike and every valve is going to be different.

exactly. ppl think that there is a chart to shimming but there isnt. each motor is as different as the diff ppl who drive them.
