Howdy David, welcome. Cracked me up. Yup, ya need 3 MBs. One your ridding. One your building and one your planing.

Looking forward to seein' your build pics. Lots of MB folks out your way.

Again welcome to the crazy. (hay, beats golf, snork)

Made me spit Oreo on the key board.

(I miss the old days when it was beer. You guys have no idea how many keyboards you cost me)

You think it would be stout enough for the torque of an engine?

OH, working on a small jet engine for MBs. I gotta make one with a "ACME Labs" plate. Is just 2 funny. Gonna be a JATO. Jet Assisted Take-Off sort of thing. Want to add an oil dropper so it smokes. Will send you pics

Remember the pulse jet powered "Buzz Bomb" that somebody posted a while back? Now that was a scary bike.
 
Here's an idea,
A rear mounted shaft drive with geared wheel. Point the shaft straight up, lol, and use the pedal shaft as a jackshaft to run to the left side. Dang, sounds like I writing a porno script. Modify a G4 so the pedal shaft runs through the 100t sprocket underneath the engine. Belts n Shafts!
You could use a left side belt for pedal drive, or maybe a friction roller that engages/disengages.
I'd have to take a closer look at how these new shaft drives mount to the rear part of the frame, but I'm sure with a little modification it would work.
Any suggestions?

Jeez. Belts, teeth, well-lubed shafts, and "modification". Excuse me for a while. I have to go talk to my wife about something. I may be back later. :)
 
I know, this topic was almost dead, but I found something that could help someone who wants to build shaft drive MB. I saw an old 70's or 80's model Yamaha 2-stroke scooter that was shaft driven. Maybe if anyone knows about those old Yamaha's they could tell us where to find parts for them. A quick internet search didn't turn up anything for me, I couldn't even find pics of a similar scooter.
