Teds new project a CB500 K1 mostly version 0.5 circa 1972.

I've had the back wheel out and sorted out the hub binding  - a very small dent in the hub flange edge  area was the culprit. Cut most of the alloy out with a Stanley Knife then a bit of polishing with a cutting wheel - cleaned brake shoe contact area plus roughed up the shoes a tad.

Next sort out the stiff throttle - just drained the tank prior to removal to get at the open & closing cables - seat removed to make it easier to access all areas.
Definitely need to look inside the engine for peace of mind.

Sounds like you have found yourself a good project Ted.

On the subject of brake lever travel, I (and a good few other riders that I know from our evening bike meets) have found that replacing the original Honda master cylinder (smooth reservoir) with a pattern type (fluted reservoir) reduces lever travel immediately, for reasons that I am unsure of, but assume that perhaps the piston sizes differ slightly?

I have a DS replica on my 400 - there is virtually zero movement.
I'll try a spare original lever see how that is if it fits.

My dirty engrained fingerprints will confirm that - I have plan A to complete - then ride it ASAP before winter sets in - see how the gearbox feels then I can see it being a pile of parts before Christmas!

Horay, balance will be returned to the Ted household

Fingerprint? How can you have those if youve been working on bikes for years

[McCabe-Thiele (Ted)]

I did once try to fingerprint a glass cutter - hardly a single loop or whirl was printed on the form.
My submitted prints were rejected twice before anyone read the note I submitted on the form.
The glass dust wears them away - still now there is the DNA option.

Most of the heavy throttle action was down to cable routing so that's one less item for now - needs a new throttle tube and grip for the rebuild but works well enough for now.
Nice chrome stopper in the handlebar end. - not sure if that's original.

Started first clean of the spare crank cases that Bryan has provided / lent me - boy was there some oil crud on the case halves. As I'm giving it some stiff brushing with petrol in a plastic box that the cases arrived in I realise petrol is leaking every where - the box has a split in the base!

Knew i should have got better cables when i built it!

Ted, I may just have a spare throttle tube kicking about. Don’t buy before checking with me.

Thanks Philip,
I've not bought a replacement yet - can't believe the cost of the grips mine are not in great condition & will not come off the tube in one piece. Cheers Ted

Beware of non oem grips. Check the length before buying.
