On the Gen 1 87 - 07 carbs, both the float bowl vent nipple & the fuel inlet nipple are sealed with o-rings and are movable, replaceable, as they are retained by the steel bracket & 2 small screws holding the idle air cut-off diaphragm cover to the LH side of the carb.
On Gen 2 08 - 18 carbs, Neither the float bowl vent nipple nor the fuel inlet nipple are ever intended to be removed or replaced.
Modify at "YOUR OWN RISK"!
Still riding my 1987 KL650-A1. 85,000+ miles & counting
