Here's the cleaned and painted battery rack I finished working on yesterday.
Reinstalled the electrical system, gauge console, front fender, and controls.
Vinyl dyed the fake exhaust hose black, and lengthened the wires for the turn signals so I could route them through it.
Seen inbetween the bushings is a set-screw collar I made which is flanked by thrust bearings. It makes sure that the axle doesn't slide in either direction.
I also installed the newer and stronger 22T freewheel on the adapter I freed from a previously destroyed freewheel.
I'm now simply waiting on parts to install the belt reduction.
