That large bolt is my makeshift flywheel puller (it's the bike's rear axle). I am under the impression that I am currently at a point in disassembly, that I need to use the flywheel puller.
So I have read 2 different schools of thought on this step:
1) Turn the flywheel puller until it pops out.
2) Hammer on the end of the flywheel puller until it pops out.
I'm not comfortable hammering on the end of the flywheel puller. I also don't have the special "Dynamo Rotor Holder" tool. I tried a strap wrench, and I busted it (although, it was successful in getting the rotor bolt off first).
So... any thoughts on how to get this bad boy off?
Thanks in advance!

I put an Electrex rotor on my engine recently, and couldn't use a ball bearing because the center mounting shaft is shorter than OEM, and doesn't provide the space for one. Had to cut some of the thread-end off the rotor bolt on account of the difference in length, as well.
Electrex RO3. Supposedly machined to exact fit tolerances...not. I'm still waiting to hear back from their technical department regarding my installation issue(s).

I'm gathering that I need some type of a "spacer" underneath my "rotor puller"?
I vaguely recall an internet post from someone saying they put a 1/2" socket in there. I'm guessing that's what they were referring to?

Does your rear axle have the Nut, or the round end with the hole through it? If the nut, use an Impact wrench. If the round, get a different bolt/ puller as it will be extremely hard to get it tight enough.

Mine had a hole on the 79 750 twin. I put a screwdriver through and tapped on it to break the flywheel loose. That sucker was REALLY tight.Motor Head wrote: The ball Bearing allows for less friction between the end of the Bolt (Puller) and the end of the shaft. So less torque is applied for the same pressure. Hopefully saving having to tighten it as tight. Make sure that there is plenty of thread still, where the bolt goes in, whichever method used. Some Anti-Seize is also a good Idea. Once the pressure id there, one good smack with a sizable hammer will take it off.

This is about all the rotation it took mine. Notice the rotor anti-rotation device. 1/4" diameter ball bearing used.
Good luck,
Jim
Edit: pictures are out of order, second is first. Rotation is clockwise.

Good Fortune!
Wow! Talk about your epic threads!
After reading that (and other thoughts on this) here's what I've decided to try first:
I don't have any spare ball bearings or a "good way" to hold the dynamo/rotor in place. So, I ordered a flywheel puller from Z1 Enterprises and will hit that with a [strike]torque[/strike] impact wrench once it gets here. With any luck, I won't need any more than that.
