Egad!

I love my Triumph, I quite like some custom bikes but would I try this?? Would you?? Jeeze, you would NOT want this to stall would you? No electric starting here.

Now that sounds like fun!
Might have to go with a smaller cal though because the recoil/vibration would damn near kill you!

This looks quite similar, although it's not open cockpit.
Can kill yourself without spending a year building a A/W 95 Choppy.

The point is...

While a pre unit 650cc triumph makes a damn fine motorcycle engine of the pre historic sort, would you want one running an aircraft? Kick start only?? single row primary chain? Egad!

Generally car and especially motorcycle engines aren't a good choice for aircraft. Real aircraft engines are designed to handle full power for extended periods of time (ie. hours) whereas car/motorcycle engines tend to run at 20-30% power most of the time.

What I keep thinking about building is the MC-15 Cricri.

Originally powered by 2 * 9hp lawnmower engines, although most built lately use 12-18hp engines (one used two jet engines).

100mph cruise, capable of inverted flight, dry mass under 80kg.
Nice video of one here: http://flight.cz/cricri/vids/v2.wmv

Michael - there are people out there that think that engine was not a great choice for a motorcycle.. And yes Sarge, the oil recycling tray... gleep!

It would sound weird on a heliocopter with the click click of the tappets being louder than the whump whump whump of the rotor...

Hardly any of the homebuilt helis are flown for more than 50 hours anyway. Just about any engine will handle 50 hours. Eventually the builder/pilot realises he/she wants to live and sells it to some unsuspecting buyer, who tries to start it, and on the offchance they succeed, run the hell away.
