Thanks, Kingbee, that’s what I was looking for. Been years since I put a shim from a kit in a Keihin carb & couldn’t remember how thick it was. I only remembered that any thin washer that I measured was considerably thicker.
Per your link the shims are .5mm or just a hair under .02”, (0.01968498”), thick.
Oftentimes you don’t want to make much of a change to the needle height. Surprised that you went up 1.5mm.
