Shimming the needles affects the main jets, which come into play, so I've heard, around 3000 rpm or thereabouts.

I did the same thing, but all it did for me was use more gas without much other effect. So I took the shims out. (Pretty easy to do--much easier than the pilot jets. And easy to reverse if it doesn't work out).

YMMV . . . . .
