It mentions an "outer lip felt seal retainer" as the last part in to complete the sub-assembly of the sprocket/drum. This may be the part I'm seeing and need to remove to get to the felt seal and retaining ring.
 
There is only like ~1mm of clearance between the shaft and the washer inner lip. I used a Proto J-shaped gapping tool to fish it out. The smallest wire .035 barely fit in and I was just able of lever the washer off.

You can see the circlip groove which sits underneath it here

When I heated the hub and tried using my bearing puller, nothing worked. But I noticed it was moving back and forth, ~1mm with each slide of the hammer weight. So, I looked a bit closer and I noticed that lip of the retaining groove where the circlip goes was fouling the bearing and keeping it in. I could move the bearing back and forth by hand, but it wouldn't come out.

I also noticed a fracture in the retaining lip, in the red box.

So, I used my dremel on the lip until i had removed enough for the bearing to come out.

See my post above. Stick a wire in there and lever it off.

Or get a self tapper

you wont need the washer or the felt if you replace with sealed bearings.

Manual, section H6,
First:
2. "Remove the bearing spacer (the shouldered spacer protruding from the centre of the bearing towards the wheel)...."
Then:
3. Prize/pry out the lipped washer.

Thanks, Dave and Les. I can definitely run a self-tapper in there to have something to grab on to.

Have you removed the bearing spacer? (H6, 2) which is still in position in your photo. :? If so, then you shouldn't really have a problem getting the lipped washer out. Yours is the later push-in type 'lipped' washer, not the early type in gortnipper's photo so it shouldn't require pulling out with a self-tapper.

As I said, I can get it to spin, but no luck so far getting it to slide out. If I can get something like a seal puller hooked into one of the spaces around the perimeter, I might not have to tap it. The bearing spacer in the center is not co-operating either. More PB and patience are in order, I suppose.

Have you followed the procedure for removing the bearing spacer given in section H6, 2 as the spacer doesn't just pull out?

If the manual procedure is followed, the bearing spacer is removed FIRST.

I'l try clamping it up in the vise and tapping the drum away as suggested. I can see how that would make it easy to get the seal retainer out.
 
Well, that worked. The rest should be easy. I hesitate to beat on something unless I know I won't be boogering something all up.
 
Popped the pressed-in cap thing. No felt seal and no snap ring, just a plain fender washer bigger than the hole in the drum. I can see the bearing, so I'm just going to pack it with grease and mask it off for painting the drum. No point in going any further.
 
Not much new to report. Got the carbs cleaned and ready for new gaskets etc. Everything is broken down into components and boxed up to be dealt with one assembly at a time. Have accumulated a few needed parts, but I'm Clark Griswold waiting for his Christmas bonus to mass order everything I'll need new. Santy is supposed to bring me a ball hone so I can clean up the cylinders and determine if I can get away with new rings or if a bore job is in order.

Thanks, Jimbo for sending out the ham can mesh! Got it coaxed back into shape and it's now in the silver paint parts box.
 
Last night I levered the 43-year-old original K81 off the front wheel, cleaned up the inside of the rim and began replacing rusty spoke nipples with the spares I got from pantah_good. Thanks, Bill! Got 3 or 4 still soaking in PB and then I'll re-true the rim when I get them replaced.

Got the cylinder walls cleaned up and found this:

Cylinders look damaged to me. .020 overbore ought to straighten them out.
 
Stock pistons off the rods. Removed the timing cover to clean up that area and renew the seals and gasket. Just a little rust on the nut that holds the driven gear on the oil pump. The camchain was quite loose, so I reset the play to spec. I think I may pop the driveside case off after I get the timing cover back on just to clean, inspect and reseal the cases. There was so much oil munge, it's hard to tell where it was leaking.

Made some battery straps. Got the hardware (except one piece, which I copied from the one I got) in a small box of misc. parts, all of which I used except for the exhaust rosette keepers.


Also got the SS clone out for a spin for a couple of hours. Temperature hit 70F, but the road surface was snotty with condensation, so I took it fairly easy. Now I have slop to clean off.
 
Picked the seals out of the steering head bearings and packed them with fresh grease.

I was all ready to reinstall the timing cover-everything cleaned and set up, new seals arrived and whaddyaknow? main seal retainer circlip came out in little pieces. I'll try to source one locally as soon as our current ice storm clears.
