I am surprised that motorcycle engines, like the BMW footwarmers,
are not a popular starting point for conversions. I'm sure there are
good reasons for that, just don't know what they are.

Whatever the reasons, they must depend on local factors, such as
availability of engines, spares, workmanship. Here in tiny Belgium I
hear about spreading use of a BMW bike engine conversion.

shows an example - observe the extra cowling width, and the very long
exhaust pipe.

Can't be sure but might well be from this place:

(and good luck with the Teuton lingo...)

I looked into this a while ago.
there are no engines available as spares so the only way of obtaining
one is to buy a bike and throw away the frame.
the bikes cost $33,000 australian dollars
a jabiru engine is less than half that and it was designed as an
aircraft engine.
does that make any sense to you?
