whats the best way to measure float height

<< < (2/3) > >>

Johnniespeed:
Ok I cheated and used the search function. The KX500 2000 to 2004 float height is 16mm +or- 1mm.
 And I read there is an easier way to check and adjust it located in the jetting section. I did not  look for that.
It is my guess that the 15 to 17mm  is the distance from the float bowl gasket surface to the bottom of the float when the carb is upside down.
 I am sure someone else will know for sure.

 I'll try to find something a little better, but check these out and see if it's any clearer.
Kx500 float levels
       Mikuni vm38ss 24.6-26.6  '84
       Mikuni VM40ss 19.1         '85-'86
       Mikuni VM38ss 27mm       '87
 
 the PWK's are 15-17mm   ('88-02')   my clymer is '83-'02
 I'm pretty sure the '02-'04 also use the PWK 39.5

BDI:
You should check your float with the carb laying on its side, not upside down. The idea is to have the metal tang on the float just barely come into contact with the spring loaded nipple on the float needle valve without compressing it. The correct height for most modern motorcycle carbs is when the seem on the float is parallel with the gasket surface of the float bowl. If your carb is overflowing gas You either need to clean the carb or replace the needle valve or possibly the float. float adjustment will not cause this as far as I know.

ID KX500:
Thanks BDI I'm guessing my needle then. I'll try that.
