I forgot to add that the paint sold at marble motors is also an exact match. I used it on the case covers of the dream. If you look at the handle bar top clamp in the PM I sent you can see.

Covers great! Order two cans at once and save on ship. I have to order a couple myself.

Bit by bit by bit...they're ready for some finer grits.  The springs are well within spec, and both measured exactly the same, so I will save the money and use them.

Too cool Gregg! Any current runners among all your projects?
They wail and weep,
The march of the sheep,
As they go to that cross on the wall.

Hey, thanks!  And, yeah I have a couple runners: my '71 500/4 and my '65 CA95.  I have both those down here in Berkeley, and I keep all my projects at my dad's VW shop in Cotati.

How funny. I'm in your area both ways. I live in Marin but I work in Petaluma.

Greggo, I stumbled across pictures of the lower fork tubes. I'll have to look the guy up.

Those do look nice.  Mine are getting there.  I've sanded out the large scratches and got a pretty uniform surface finish with the 320 grit.  Gonna spend a little time with the 400, then 600 and see how they look.  I have some Nevr-Dull to finish it because I'm still not sure about clear coating them.

If they appear to shinny you could always use a flat matt top coat. Sure you figured that already. I did that on the CT90 build.

I believe I am good.  I will throw in the black RH control too. Maybe it could be salvaged and save more to go to your build.

Greggo, Please enlighten me: What is a "two-hole rear hub" and a 'Rolled rear rim" ?
I see in  the parts manual that there was a change in rear hub part numbers some way through the K1's run but what's the difference?

regards
Thomas

Thomas, the outside edges of a rolled rim have no flat spots like a newer DID rim.  It's a subtle difference that can be hard to see in pictures.  They were only on sandcasts and K0's, and I'm not even sure how far into K0 production they started using the flat edge design.

The hub is explained easier with pictures.  2-hole hubs were installed from the first few hundred bikes (very first ones had no holes, like MarkB's #97 bike) somewhere into K0 production.

2-hole hub:


4-hole hub:

OK, thanks, I think I've got it. We're talking those big holes behind the cush rubbers, your first photo only has two and the second has four? I'll have a look at what I've got. I have 2 spare rear hubs hanging from the rafters.
And I'll also take a look at the rims I have and see if I can see any differences there.

Is all this info available somewhere on this site? Or on the SOOC site? If so, please point me in the right direction.

Correct.  Sorry for the crummy google pics.  The thing with the rim is that there are no flat areas on the vertical edge of the rim.  It is rounded from the edge of the spoked area to where it meets the tire.  If you look at brand new DID rims, it is clearly flat on the edge.

I believe most of this information is available on the SOOC site, but if you search and read around here, most of the differences can be gleaned from build threads.  MarkB's builds are a great place to start, and make sure to check out the list of differences on the SOOC site here: http://cb750sandcastonly.com/smf_forum/index.php?topic=217.0

He sent me everything except the extended chopper forks, so I'm assuming I have what I need. 

Here's what I got:

I think the parts in the bag is what I am referring to. They should slide over tubes and settle on the bottom.. If not I can remove them from the tubes I have and give you them.. I have no need for them

Good news first?  Okay, good news first.  Got my single cut front fender, two-hole hub, and a rolled rear rim. 



No dents on the fender.  I don't think I'll have any metal work to do before it gets re-chromed.  I'm really happy I didn't have to buy a repro from overseas



There's some water inside the rim, so I'll have to see about that so I guess that's the bad news.  I tore down the wiring to the main harness, and pulled the headlight shell.  It's cracked at the top screw to the ring, so I'll have to think about replacing it before painting.  The harness is in horrible shape, and I'm not sure yet that I can save it.  It's hard to keep costs in line on a bike like this.  I want it to look new when it's done, but so many of these parts are beyond repair.  So many stripped screws, and corroded connectors, and dried out rubber, and brittle wires.  I still have to pay for spokes, and pipes, and re-chroming, and paint....wow.  I admitted to my dad that if I'd had more money I would have started with something nicer.  He's been trying to convince me to take that advice when thinking of a early 911 project and I think he's on to something. 

Here's how I left it until next week.
