Factory spec for the 26mm Mikuni carbs is 21mm.

It can/will fall out of spec over time. Reputable shops/tuners will recommend checking it every 3 to 6 months, pro bikes are set prior to every race.

Your question about raising or lowering the float for certain conditions is a good one. Companies such as Holtman make products that allow you to do that using manifold vacuum to compensate for temperature and or altitude. Pretty popular with the snow machine crowd. Some tuners like to vary the level when they are dyno tuning etc to see what affect a richer or leaner mix will make on their readings. It saves a lot of time when you may be dealing with 4 or more cylinders. (the drawback to that is once you have found the air fuel mix you want you have to work it out in jetting, as in many cases the level you may have the float at to achieve may or should I say probably will give you a different set of problems once you start turning,,and leaning etc.).

If you find yourself at really high altitude etc and need an overall leaner setting, you can play with it as many have done. Some Supercross riders years ago were running them a little higher than normal so they wouldnt experience a lean condition over the whoops. Over the years it has been played with a lot. Most find with the newer carburetors we have now, that the stock setting is the best overall for starting and running smooth.

Faded's post on how to do it is the best I have seen. Read it.

I have been reading it to get the info I have. I just want to measure from right spot. Am I right to assume(bad word) that I measure from where the top of the float bowl would set?

These guys are right
Here is another pic of an actual banshee/blaster carb being set at 21mm. The measurement if from the gasket surface area to the top of the float with the float tang JUST touching the valve but not compressing it.
(I just said tang )

You can test the float level for being correct by doing a 1/4 throttle plug check or you can do it by the seat o the pants. For the most part when re-jetting, the float level is adjusted when the 1/4 throttle jetting is off and one does not want to fool around buying smaller or larger needles. Over jetting on the pilot and clip to compensate costs you a lot of power so you best to leave them as lean as safely possible.
You must however, set the float level before you set the clip position and main jet. Any adjustment to the float will change all the jetting circuits. I find it's easiest to start rich and work you way leaner. 1mm at a time if doing it by the seat o the pants.
Start at the bottom with the pilot, then float level (if needed) clip position then main jet.
And YES the float level can be adjusted to compensate for altitude and different air temps.
For instance winter riding you may want to lower the float level to 20mm and up the main jet 1 size. This CAN make for more accurate jetting then just changing the main jet and mixture screw setting. Same goes for high altitude if itís too rich raising the float level to 22mm and lowering the main may be needed.
