Managed a few more hours in the garage over the last days adding more parts, adding stainless washers everywhere (rust free) and even shake-proof washers in hot places where I'm not sure a nyloc would survive.
This stuff takes ages, but progressing.

Installed the rear wheel and all brake links, tedious in the tight spaces, centre stand on and return springs ordered.
On the left side could finally mount the one half of the exhaust with copper plated shake proof nuts on the so delicate looking M7 studs (all new).
Stainless clamp of course and silicon to seal the joint (high temp spec, not B&Q).

Clutch cable in with small tensioner spring (typical Honda detail which make these classics so nice), chain on, new, and chain guard all on.
Keep on looking at the wires, hate electrics, so putting that off until it is unavoidable.

Hope to do the front wheel with its fancy TLS drum, cables an speedo cable too. Cables came from Taiwan and are superb quality, even have the plastic anti-rattle sleeves on the handle bar ends, so nice and 1/2 price of anything in the UK.

Yes...quite.
The tyres don't fill me with confidence tbh, feel a bit hard to me though they are 3 years old, never been on the road. :)

Spend all that time and money on a restoration then use tyres you're not happy with?
A no-brainer, as our US cousins like to say.

Tyres can spend years in the warehouse waiting for a buyer.
As long as they are wrapped and don't spend time in the sun, they are good to go. ??

They can spend years in a garage waiting for their next ride.
As long as you take it easy to begin with, to rub off the 'skin' they form, they are OK ?
Knowing that the tube inside is still serviceable may be of more concern.

What is the official proclamation of time expiry ?

I have tyres on one bike older than that Honda, no problem, but I don't race it.

New tyres are always nice on anything, you can have new poor tyres, and older great tyres...
Not sure what tyres are best, possibly not the most expensive.

They came from a reputable supplier who did the new rims, spokes and tubes.

 few more hours in the garage on the bike progressed things a little.
I think after this post I'll slow reports down until a major milestone is reached.

Missing on the bike was the second pair of exhaust sleeve halves, and as these are also hyper rare (at a reasonable price) I made some from metals I had around me.

That job done the front wheel went in and after a few tries finally sorted the tls lever travel out so I have max leverage at just before contact of the shoes.
Other parts should arrive tomorrow to finish off the mech parts of this rebuild tomorrow, then it has to be the electrics...

The proportions of these little Honda twins is just so right.

On the subject of oil:

The Haynes manual stated 'Castrol GTX' oil, with no further info.

For this little CB what modern oil would be best suited?

Oh no, not an oil thread!
Cheap 20/50 and change it yearly regardless of mileage (obviously subject to doing either no miles at all or an astronomical mileage)

Yes, the curse of any car or bike forum!
I'm sorry!!
Wet clutches and modern formulae in oils made me wonder....

I use the Castrol 4T in all my bikes with no problems.

Moses went to Mount Olive so Popeye hit him.
Getting grumpy, but not as grumpy as mini-me.

Only Mini can put a smile on my face after another 3 hours on this bike's wires!

Looks like the starter solenoid is cream-cracker'd, so to the flasher relay, but got the neutral position circuit done and a few other circuits.

Slowly, slowly catch the monkey. The Gold bike was the same.
