AMF Roadmaster Tech

So my friend Alex was working on his AMF roadmaster... I couldn't resist grabbing some pics. The friction drive roller disintegrated and he was able to find an NOS one!

I think the coolest thing about this bike is that it was a solid state ignition - either Transistor or SCR, but I didn't see any caps in the potting. Regardless, it was breakerless and pretty cool for being such an otherwise crappy bike when bikes of superior construction still had breaker ignitions in 1978. Hell, there were cars that still had points in 78.

He has it running now. Haven't gotten to bum a ride yet, but I plan on it...

Stator pr0n - no points man. Like 80w of light power though.... WHOA.

SCIENCE. solidstate brings all the boys to the yard

Clutch. Seemes like it actuates both ways... swings one way to start (little pads) then the other way for drive engagement (bigger pads). No key way or taper. Just clamped on.

The MAN himself.

  1. The silver-gold item in the top left of the ignition circuit is the capacitor, a foil type.
