For a month ago i did a really good carb cleaning,And i also adjusted the float heights with a vernier caliper to the specs i the manual (22.4+-1.0mm),Since then the bike will not run good at high speed range.Feeling that the bike dont get enough fuel.Today i borrowed a adapter with a plastic tube, connected it to the the float bowls screw.Now it seems that the level is 4-6 mm under the spec in the manual that say: Fuel level 5.0+-1.0mm. I now wonder: If my carburetors are upside down and the bowls removed,Witch way should i bend the tounge of the float to get a higher fuel level???
 
Bend the tang towards the float needle

Far be it for me to question a site superstar, but; If you bend the tang down towards the float needle, that increases the float height, but doesn't that decrease the amount of fuel allowed in the bowl? I am pretty sure for my carbs bending the needle down decreases the fuel but bending it up increases the fuel.

ohhhh BUUUUURRRRRRRRNNNN!! hehehehehe just razzin ya Bill. Its easy, if you're just thinking about it, to get it backwards, because you have to think backwards to begin with, then invert it, then think backwards again.. so its then forwards...

One step forward... two steps back...we come together cause

Brain fart. I'm wrong.
I didn't put that superstar bit on my title.
I'm no superstar, that's for sure.
 
To get Fuel level 5.0+-1.0mm,My floats now are between 20,2mm-20,8mm. 22,4 like the manual says are long gone for my carbs???

I used just an item like that, when i measured the float heights
 
Tompasio,
If your measured fuel level(s) is (are) at 5mm+/- 1.0mm, it doesn't matter what the float to gasket surface measurement is.

example... http://www.thegsresources.com/_forum/showpost.php?p=1043104&postcount=4
when I set the float levels to the recommended height of 23mm, it was almost impossible to get it running correctly. I set the fuel levels externally to 0 -/+ 1mm from the gasket surface, with clear tubing attached to the bowl drains and arrived at a 20.5mm float height.

my musings on the subject of fuel levels... http://www.thegsresources.com/_forum/showpost.php?p=1046269&postcount=3
