There is an easier way to quick check the float levels. Put the bike on a stand or otherwise level it. Slide one end of a clear tube on the float bowl drain nipple and hold the other above the fuel tank (like, tie it off the the handlebar or just hold it). Crack the float bowl screw open. The fuel line should be +/- 1/8 inch from the gasket line between the carb bowl and carb body.
