Valve shims

Well, I will soon do a major maintenance on my scoot (AN400). New belt, clean variator, oil change in FD. Check valves. "About as much maintenance as a man could want"

If the valves require adjustment, I understand the procedure, and how to figure what thickness of shim I need.

Will the dealer measure the existing shim for me? I have only a plastic micrometer. I have read that the thickness is marked on the shim BUT measure it to be sure.

Thank you!

The Schofield Kid: Yeah, well, I guess they had it coming.
Will Munny: We all got it coming, kid.

The shim has the size marked on it.

What YEAR is this BEAST!
07+ have the bucket and shims. IDK what the early ones had. The shims have the number stamped on one side, and the side with the number should be turned down in it's pocket, making the only way to read it is to remove the cams and remove the bucket and shim on the underside if the buckets.
It's too bad that they made those shims the WRONG WAY! I remember my old Honda 1977 CB750 had shim on the top of the shim, and there was a tool to insert that would pry the bucket down and there was just enough room to use a magnet to slide the shim out, and put another one in. It was a lot simpler and easier that the Burgman setup. Oh Well.....

The little shim on top of the valve tip and bucket on top makes for a lighter valve train one large shim on top would weigh more than all 4 small shims

I had one of those shim tools for my old GS1000

Mine is a 2008.

Yes my 77 Rabbit had shim-in-bucket-over-valves.

Yes I know the thickness is supposed to be stamped on the shim. But my motto is "Trust but verify".

You'd need to buy 0-1" or 0-25mm micrometer if you want to be accurate.
