XV535 - Setting float levels on the bench

For the XV535 (Initial bench set up never to be substituted for final adjustment via the tube)

See the shape of the float and that casting mark circle on the jet block? When the float height is set correctly, the edge of the float will be exactly the same as the casting mark, like the edge of a circle on the edge of another circle. The carb on the right is set rich, and the one on the left is set lean, but close to where it should be (see the circular casting mark?)

Here it's set just right.
