Looking forward to hearing some vroom, vroom.

Mailman you pictures of the 1972's cluch disk made me decide to post some OT pictures of what I pulled out of my 1992 Sporty, note this bike was being ridden as recent as 9:30 this morning, but knew the clutch was a bit dodgy!View attachment 123075
Don't think that one is in spec!

And for the steel plates, I don't think even Mailman can smooth out those bumps and grooves!
I did not even take a picture of the pressure plate or the clutch surface of the clutch hub, both I would estimate as having 0.010 grooves worn in them! Only good thing is new factory parts are available from "The Motor Company", I'm going with a Barnett "extra plate" clutch and Harley for the pressure plate and hub. If it was an XS650 clutch I could just walk out in the barn and find a good usable stack of parts!
Well this Sporty has 40,000+ miles on it and the last 24,000 pulling a sidecar no idea of what the original owner put it through for 16,000 miles so maybe it's not that surprising it is worn out. If the new clutch lasts 40,000 I'll be happy or not around to care!Haha! Well Ken, nobody can accuse you of not getting your moneys worth out of a clutch!
Got a couple more jobs done today, only about 500 more jobs to do before I’m done!
I began by checking my new starter gears spring for slip resistance. This new gear has a MUCH beefier spring than my 1972 original. The original gear spring slipped at only two pounds of pull. The new gear initially required sixteen pounds of pull, which would’ve been great , but it soon wore in and became more like eight pounds of pull required. So I gave it a little squeeze in the vise and rechecked, now it’s good for twelve pounds of resistance. I’m ok with that.

So, I had my engine flipped up on its side, it was super easy to work on the gears in this position. Just a note, I oil everything when assembling, every gear that runs together, any surface that it spins on, every friction point gets oiled as I go. Starter gear and return spring are in.

Gear #3 and #2 are back in with all the various washers and circlip. Everything buttoned up and slides and works as it should.

I then turned my attention to the clutch pack I bought from Daniel Black, the later model assembly, believed to come off a 1975 model. The steel plates needed to be cleaned up, as the friction discs had rusted to the plates.

So I set up my bench grinder with a brass wire wheel and went after them.

When they were clean I checked them for warpage on my piece of heavy glass.

Once I was sure they were all within spec, I gave them a final surfacing with some wet sandpaper to smooth them up. I also cleaned up the surfaces on the hub and pressure plate.

At this point I was looking at the original friction plates, which I had intended to use. As I was looking at them I could smell a distinctive burnt smell. I measured their thickness with a caliper and they were worn just a little past acceptable, so I ordered new EBC friction plates this afternoon. Lots of stuff to busy myself with while I’m waiting.
Anyhoo......it’s always nice to have the starter gear done!
Was just typin' the same when your message popped up....Make sure they are not stuck together. Looks like they are. I think I see two lips.
Bob, those seals look to be rotation specific. There's a rotation arrow and the lips look to have a labyrinth type spiral to them. Both have an 'R' after the size which looks to match up to the labyrinth spiral direction. You need an 'L' and an 'R'.......
