Float Heights
I finnaly got how to properly measure float heights. This can be pretty confusing and frustrating for carb retards like me who are visual learners
Factory setting should be 22mm and it looks like people go with 24mm if a Jet Kit is installed.
Also remember. While pressing down on the "tang" the float height will increase ,pushes the fuel inlet valve down (creates a leaner condition) . While pulling up on the "tang" the float height will decrease ,brings the fuel inlet valve up(creates a richer condition)
You measure from the gasket surface of the carbs to the top of the float or between the flower and the "C" on ragedigital's card measurment picture..over here viewtopic.php?f=8&t=891&hilit=adjusting+floats&start=15
Next hold the carb at a 45 deg. angle as shown in the 4th picture over here http://www.factorypro.com/tech_tuning_p ... edure.html
Make sure the "tang" does not compress the needle valve(fuel inlet valve) "bumper" . While tilting the floats until the tang barely touches the fuel inlet valve bumper , take measurments. I think that the FZR fuel inlet valve bumper is pretty stiff and it will not compress when the tang touches because of the float's weight.
This does an awesome job at explaining and identifying various terms such as : float assembly , float assembly tang,fuel inlet needle valve,fuel inlet valve seat ,and fuel inlet valve bumper(one you should not compress)
