1. Form Follows Function
Function: Need bread.
Form: Take some wheat flour, salt, sugar, shortening and yeast. Make bread.
A good thing.
2. Function Follows Form
Form: Someone used too much flour, no salt sugar or yeast.
Function: I have a brick
But, I'm hungry!!
Not a good thing.
The purpose of setting the float level in the carb is to allow proper operation of the carb..its fuel delivery, mixing of such with air to provide a properly atomized ratio of fuel/air to the engine.
The purpose of the carb is not to not pee.
If you have some other problem (bent float arms, corroded/gummy needle seat, degraded needle tip your carb may well pee with a float level of 6" (hyperbole for effect ;) )
While that may be at odds with the whole idea of dropping the float level to improve bike continence, it depends on which comes first...form or function.
Sheesh..there is a point here someplace....
It is changing your float level based on whether it pees or not isn't a good idea.
That was much simpler, 'eh? (but not as much fun...and I get paid by the word!)
If a float level of 17mm (spec is after all 16mm+/- 1mm) still pees, another problem needs to be addressed.
Honestly, I didn't go through a jetting sequence (plug chop, subsequent plug inspection and such) to check the result of my float level change. It's within spec and the carb otherwise is operating properly.
Jetting changes taking thousands of feet el. change and huge temp variants into account keep me busy enough as it is.
