Anyone have a suggestion what might be causing this?

i dont know a lot about those but muthey or someone else that might, should see your post but for now, are you using chinese bulbs?

are you using the right watt bulb?

you can check the voltage at the lite socket or the battery at idle, then rev it up and if t goes over 15 volts, the regulator might be bad.

shaft or chain drive does it have a 3 way key switch or 2 way? reason I ask those questions will tell me what your wiring system should be if it is a chain drive I am leaning towards a shortle lighting coil, if it is a shaft with 3 way key then it might be the voltage regulator, as the way these machines are primarily wired is the lights run directly off the lighting coil. Before you start tearing into the stator do yourself a favor and check over the wiring harness and look to see if it has been hacked into at any time, if it has you might have a shorted wire. Does your green neutral light stay lit even after the others pop?

Chain drive, no key switch, pull start, no battery, no neutral light. In answer to a previous post I got what was supposed to be the correct bulb directly from Yamaha.
