There is no leaking when on the side stand. It is a brand new bike so seems like it wouldn?t be wrong from the factory, but why are so many floats set incorrectly?

Firstly, we usually set the fuel level a bit lower than Keihin specs due to how the carb sits in the chassis. Helps with splash over fuelling on downhills and haven't had issues with running short on supply during WOT.
Secondly, I don't think they would be checking the level on every carb produced. The tang would be attached the same, but any tolerances are just that. Also, if any bumps to it occur during assembly, or transport (no fuel in it to soften the movement of the floats) then that could move it out of spec a bit.
People have used some cork with a bit of clear tube through it, push it into the drain hole in the base of the bowl and run the tube back up. Fuel on and it'll rise up to it's level. Given that there is no room you'd still have to remove the carb from the bike.
Cheats method is to turn the fuel on, and start leaning the bike over. Take note of when the fuel starts to come out the overflows. It should be around 45degrees or a touch past. Any sooner and the fuel level is too high.
And just to confuse things, high fuel level = low float setting.
