Motorcycle chain would work, but car and motorcycle transmissions with
chains inside them don't use motorcycle chain. Silent chain is much
stronger, quieter and wears a lot longer.

Don't do what I did, buy a sprocket that needed 13 splines on the
shaft, unless you have good indexing and milling equipment.

I have a small mill/drill and a rotary table with B&S plates.
No shaper though....
I guess it would be possible to use the quill plunge and RT as a
"manual" shaper, at least for the ~2.5 inches of the quill's travel.

What I do /not/ have is a suitable attachment for shaping with the
mill.... (scribbles down another project...)

Bicycle sprockets are easier to mount:

I don't have a shaper either. I milled the spline grooves with this
shop made cutter:

The other end of the bit is a close enough copy of a tooth in the
sprocket bore that I could jam the shaft into the hardened sprocket
with a hydraulic press. I cut the grooves slightly deep to avoid an
interference fit where it didn't help, the shaft OD was easier to fit
snugly.

I will probably just use some double-strand roller chain & sprockets
from McMaster-Carr. The places that sell silent chain all seem to be
commercial-sales-only, or too busy to answer an email.

Are you going to enclose this drive and run it in oil? Roller chains
work fine exposed with only occasional lube.
BTW my old Honda 350 used a roller chain to drive the camshaft.
