Oh man, talk about a tease. I’m hoping they didn’t try to run it with the timing off.

....looks like those downtubes are pretty smashed.
bummer!

Pull the plugs and ensure it isn’t hydrolocked. Run/Stop switch to stop.

A little more info:
The engine will not turn over via the stator bolt, or the crank pulley bolt. My experience with these engines is with the spark plugs removed, they can be rotated quite easily from either of those two access points. Today the cylinders got a good drink of "cylinder rebuild from a jug" (Acetone, ATF, and Kerosene). 30 years ago I may have been tempted to use a breaker bar and a 3 foot pipe but experience over time has shown other ways often yield better results.
-
While that potion is working its magic, I'm gathering the ignition components. There's no wiring on the bike at all except the two short pigtails at the stator and pulse generators. There are also four "three foot spark spark plug wires" that run inside and down through the "down tubes". Upon exit, they run up in between the heads/cam pulley cover, then off to the spark plugs:

The two coils that were in the box of electrical test outside of the ohms limit and one has a sizable crack down the side.

The two vintage ignition modules are also in the box, and as a mock-up, those and the coils were temporarily fitted to the gusset at the gooseneck. Based on the spark plug wires routing up through the down tubes (which are in good shape in spite of what the photos look like) it seems like that's where these items were intended to go:

Lots of excellent original work has already been done on this wing and it deserves to live. The complete and excellent running 1980 GL1100 here is my ace-in-the-hole if truly needed but as of right now, plans are to work with all the project bike's existing parts as much as possible and leave the 1980 in-tact.

This purchase is all about "the experience" and I'm guessing this latest project bike won't be a disappointment!

Most likely someone over-tightened the U-bolts that clamped the crash bars to the frame.

The downtubes (less the grinder marks) are amongst the nicer ones I've seen. What am I missing?

In the first photo in post #29, it appeared that they were dented. My mistake.

No problem! I thought maybe I had overlooked something - which wouldn't be the first (or last time)!

Onward!! :crosso

There's hope for this GL1100 engine. After about a week now, a partial rotation of the crankshaft was possible. With a bit of grunt it may likely go all the way around but the plan is to give it another shot of ATF/Acetone/Kerosene (shaken, not stirred.)
-
In the meantime, life has been found via the pulse generators. The ignition system is temporarily wired in order to test for spark... And look at that lovely crack in the coil!

And the pulse generators located at the rear of the engine:

And... we have ignition!

not how I would tie one down! The tie down points should be on areas not sprung, such as rear swing arm/axle and bottom of front forks. The way that is the bike will bounce under the "over straps" and I bet the sub-frame-side stand will be trashed.

I'm not an engineer, but IMHO it seems to me that Mama Honda had a reason to support the rear drive on both sides. I would be concerned about the stresses that a single sided spring mount would put on the shaft tube and the rear axle assembly. But what an interesting concept. Good luck. Maybe wait until that time when we get too old to ride comfortably on a bike like that, finish building it up and get someone younger to test ride it! Preferably someone with good insurance.

Single sided swingarms are on other bikes today, including the Goldwing. It probably needs considerable stiffening to support it and keep the sides from flexing. I’ll bet the one Cyborg built a few years ago would take it.
