Yes the shims are used to adjust the minimum stroke of the pump so you use as many as required to get the clearance right .Tone.

My point exactly, shims nave no impact on carb sync or pump cable adjustment. OEB |

Behind the adjuster plate.
So remove nut, washer & adjuster plate and add or subtract shims.

What you need to do is check the minimum stroke .To do this if you start the engine and with the bike ticking over watch the adjust plate at the end of the pump under the small nut and you should see it move a small amount in and out. What you need to do is is stop the engine with the kill switch the moment it moves out to its furthest point out then check the clearance between the adjust plate and the raised part of the pulley with the throttle closed. You should have a clearance of 0.1-0.15mm or 4 to 6 thou and this is when you add or subtract shims to get the clearance right. Make sure you double check it otherwise you might end up with a seized motor . Tone.
