Tell us more about this in-line generator. This is the first I've heard of
it and it sounds interesting. Is it a commercial product? From whom?
There's quite a bit of discussion of it in the archives. The generator comes from a Harley-Davidson motorcycle, and
there are several companies making aftermarket pieces. Compufire seems to be a leader:

The general idea is to bolt the rotor to the front of the flywheel, and the stator to the back of the gearbox. One
builder has already modified a previous iteration of the RWS PSRU, but it required more machine work than I think most
builder want to contemplate in order to free up enough room for the parts. I'm using a one off PSRU which allowed me
lots of room to install one. If Tracy's new design frees up some room between the gearbox and flywheel, this could be
an easy installation to eliminate mounting hardware, a belt, and pulleys, and free up the under-cowl space for something
else.

Don't know the dimensions of the generator in question but one of the
design goals was to change as little as possible, so the distance
between engine and gearbox was unchanged.
Off the top of my head, the rotor is 1.25" deep, and would need a 6" dia
flat on the engine side of the gap, centered on the shaft. The stator
fits completely inside the rotor, so it only needs 1/8" to allow for
routing the wires out. If the space has been expanded even a small
amount, it should allow for a relatively easy addition of a compact 38A
generator, eliminating belts and pulleys. I only have a microscopic
amount of time on mine, but it has been working so far.
