Cb750k0 - any interest?

Nice job WA,

A full write up on the disassembly ?? Nice tip on the glass as well, didn't think to use headlight polisher on glass, thought it would be to hard for it
think you will fine that those early gauges are plastic faces not later glass ones with metal shroud's

Yea they are plastic. That’s why I put glass in quotes.

That said, glass would be much less prone to scratches and probably hold up better over time (minus breaking)

One of the things I do for a living is cut/polish scratches out of glass. Very possible. Could actually use the same process, just need diamond pads to cut it.

To polish out light scratches/scuffs, heavy oxidation and water spots use this on a felt pad and a variable speed polisher.

@650Skull - I will do a write up when I get a few mins. (I think I took pics of most of it).

Still waiting on my gauge bits to show up so I started taking my forks apart.

Probably the easiest forks I’ve ever pulled apart.

Had to track down some NOS seals cause new ones don’t seem to be an option but they were priced about the same.

Cleaned everything, flushed em out and gave em a “factory” polish. I didn’t get rid of every little nick and scratch and where there were casting marks from the factory, I just wanted em clean. Found some pics of NOS lowers and tried to match the shine of them.

Also, cleaned, prepped and painted my triple tree. As well as install from taper bearings.

Used a single stage urethane and gotta say, I am quite impressed with it. A product called “vintage flatz” - satin black. Looks period correct.

If I don’t get my gauge parts this week I’ll probably pull the motor and paint the frame next weekend if I’m lucky.
 
Gauge parts never showed up, pulled the motor earlier this week and started painting. It was fairly easy to get out laying it on its side, but getting it back in is not gonna be easy…

Got my center and side stands, battery box, tool tray and front wheel disc painted.

Cleaned, prepped, primed and sprayed my frame.

Did some testing and satin was too flat, gloss was way too shiny so I went with a custom mix.

3 parts satin/1 part gloss single stage and I’m quite happy with the turn out. - vintage gloss.

Also got my bars built and cleaned up my coils.

Makin a little progress on getting the front end together. This is about as far as I can get at the moment. - I need to polish the front hub and get a tire mounted.

I did get my gauge parts in so I can finish those up later this week (hopefully).

I got rear shocks on order, As well as front brake lines.

Still need cables, a seat, side cover badges and exhaust heat shields - I believe that’s all though. Ohh and a very specific plastic chain guard that is quite elusive haha.

Rear hub needs a polish, new shoes and a tire as well. Pretty sure I’ll be running K70s front and back.

Also started to get into the motor a bit, but it’s a job for another day. Probably when I get the bike almost back together.
 
Got my gauges done, here is a full run down of the process as requested.

Here is what they looked like when I started.

These were fairly easy to open up.
Started by clamping them to the bench and hitting the outside plastic covers with a heat gun and used a small flat blade screwdriver to get the crimped edges up. The edges are old and brittle and pretty much broke during the process but that’s fine because they don’t need em to stay put because the metal housings are still a snug fit in the plastic covers and they get clamped in place when mounted (reproduction covers don’t even have the crimped edge)

After that I pulled the guts out of the speedo and gave em a good cleaning, greased or oiled all the moving gears as needed.

The speedo is unique in that it uses a silicone oil in a dampener to keep the needle moving smooth and not jump around. Both my speedo and tach were in great shape mechanically so they didn’t require more work than a good cleaning.

As shown above, the plastic housings were sanded and polished.

I only had to replace the rubber insulation boots for the lights on my tach which consisted of clipping the wires, working on a new boot and soldering the wires back together. I didn’t get any photos of the process but I think you get the idea.

Then it was time to re assemble. I got new faces, jewels and light boots.

I used some CA glue and activator to secure the jewels in place and then, put my light boots on and screwed my faces on, using a bit of blue thread lock on the screws.

After this I needed to touch up my needles and Testers Fluorescent Red is a perfect match. (Back side of the needle had some original color left)

Pushes my needles back on and double checked my how they functioned with a drill and old cable cut off.

Popped my plastic covers back on and that about sums it up.

Quite happy with how they turned out. I am still missing a few small rubber bits but they are on their way as is the main rubber for mounting.

***I used a soft bristle brush and purple power degreaser to do all the cleaning of internal parts and metal housing. Turtle wax chrome polish that I’ve had for at least 15 years for the back cover.

And if there is anything I missed, or questions I did t answer, just ask.
 
Those came out really nice! Great job on them, they look like new! 👍🏻

Can’t have the XS2 parked next to a jalopy haha.

They do have a few little tiny flaws but beats having to buy some NOS ones. There is a tachometer listed on eBay at the moment, only $1,400, and someone will buy it.

I got about 200 bucks in parts and shipping to bring em back to life. No US supplies, all came from the UK and Canada.
