Let's see... I do believe the light is supposed to go on when it's in neutral.. duh. Now after that bit of sport, remember the interlock that prevents the bike from starting unless the clutch lever is in if the interlock has been told the bike is in gear ? There is a diode in the wiring harness under the gas tank.. now does that start you thinking Bunky ?

What about a N indicator light that pops on when the clutch is pulled in OR when it's in Neutral?
