Thanks Gunner; a way to go yet, but I love all the challenges.

So I managed to scoop up some garage time after dousing myself with a bucket of enthusiasm. Here's where I'm at after an afternoon's peaceful pleasure away from Her and Her Self-Loading Galloping Gob.

Looks like the transmission needs a bit more attention than I thought, but I'm ready for unforeseen eventualities!

I've taken many pics as aides-memoire for the rebuild and for posterity; here's a few, highlighting some salient points:

So you got another Superhawk? I've been kinda absent. on the Honda SOHC forum trying to get my CB750 together.........

No, same one. I've just added a CB250K, for playing with when I'm back in Blighty.

Well chaps, a good afternoon's work yesterday: I dumped my partially-disassembled motor into a plastic tub and took it to the local filling station/car wash and power-washed it with hot water & detergent.

Back in the garage I strapped it to the makeshift mobile workbench -- an old, glass-topped drinks trolley overlaid with a slab of 40mm Formica-clad kitchen worktop -- and set about pulling the top end and jugs off. It all went so well that I ended up de-studding & de-dowelling the casings and going the whole 9 ya.... sorry, 8.2296 metres!

I'll do some editing, adding some pics a bit later.

Some salient points:

• The oil hasn't been changed in about 2500 miles now, but it's remarkably uncontaminated and viscous.
  There's no visible crud in the oil spinner.
  Cam lobes look pretty good, but I've not pulled the rockers out yet.
  The cam sprocket is missing its neoprene buffers.
  The kickstart/countershaft ass'y had so much endfloat that first gear's flange has been grinding away on the end of the shift-drum-guide / kickshaft-stopper bolt.
  The plugs remained a beautiful sandy tan.
  It's been rebored once, possessing +0.25 pistons (I have a new pair of +0.75s for the project).
  Their crowns aren't too badly coked -- the '0.25' is clearly visible.
  There's been little, if any, piston blow-by; but one piston's skirt shows the evidence of the seizure experienced on my delivery ride of nearly three years ago.
  No lips can be felt at the bores' upper circumferences.
  The gudgeon pins are pretty sloppy in the conrods, but a very close fit in the pistons.
  No sign of roller or bushing wear anywhere on the k/s shaft; the pawl is well-shagged.
  All the gears' dogs' reverse-tapers are in nice order, although there are some tiny chips on the edges of two or three of them.
  The shift forks' contact pads seem in good fettle, showing no sign of burning; but there are abrasion arcs on the forks' main structures. One very odd(?) observation: they're chromed.

More later.....

Very thorough check over.
