Hey folks, finally got my May of '72 piggie wheelin and squealin again, but the hi/low headlight switch is turning into the turd in the punchbowl. I don't want to destroy the center padded button on the wheel. Does it just pop off? Screw off? Any tips on how to remove the wheel to get at the turn signal switch without breaking anything? Do I even need to pull the wheel to clean those contacts? Not having any luck (surprise) finding a new one, so I'll see what I can do with this one first.
