Lower measurement (higher level) is richer because it takes less vacuum to draw the fuel up the shorter distance. I believe that they warn not to adjust it more than 2 mm .
.........Just checked the Burns article, it's changed and only says not to adjust it.
Found the old article ver 3.2,...
Float level: Higher float levels richen mixture at full throttle low rpm, and part throttle high rpm, lower leans it, but do not change it more than two millimeters in either direction of 9mm. I have caused myself more headaches playing with float level on FCRs than any other adjustment of the carburetor. If you can possibly run the floats at 9mm, do so. To set float level, with the carbs off the bike and the float bowls removed, hold the carbs in such a manner that the float pivots are above the floats. Tilt the carbs until the float you are adjusting just kisses its float valve needle, but doesn't compress the float needle's internal spring. Measure from the float bowl sealing surface to the highest (lowest with the carbs mounted to the bike) point of the float at a 90 degree angle to the sealing surface. Bend the float tab that touches the little nub on the needle to change the float height.

i didn't believe in adjusting the carb float and peoples improvements were down to the bike being wrongly carburated and the changes helping and NOT the float height per se.
mr burns has just about got it spot on now and at least he's prepared to change his position on things. good on him-takes a big man to say that.
