Honda-SOHC

Yes, I went.

Me too.
My Trident was behind the Indian that won Best in Show.

Apart from the paint and typical US high bars looks reasonable.
Will have lights on all the time but a UK rh switch unit cures that, the rest is just paperwork and service items hopefully.
In Ash's dropbox you should find the honda manuals and parts books then apart from a decent metric socket set(3/8 drive 6 sided sockets) circlip pliers and some jis screwdrivers(+ impact ones) you are good to go.
There are only a few special tools( clutch nut, hub bearing retainers, rotor puller) and if you can assemble a Commando the Honda is dead easy.

Thanks for the helpful info.
I didn't know about the headlight being on all the time, so it sounds like a RH switch unit is on the list of parts.
Presumably I'll need a new headlight with left side kick-up too for our left side driving.
I had an impact uni-driver with long JIS bits back in the day, but lent it to someone...
I have a good tool set (metric, AF, and Whitworth), but I don't have any JIS screwdrivers - they're on the list.
(It's amazing the number of people who don't know the difference between Pozidriv, Philips, and JIS.)
I can do a Commando clutch easily, so it's good to know that the Honda will be just as easy.

I did find a load of manuals and parts books on the US SOHC site - it's so confusing with all these forums.

It's customary to introduce oneself to any new forum, so here's mine.
I'm a member of quite a few forums for the very good reason that there's a mine of useful information on them.
I'm retired, and my formative years are the seventies.
As such, I seek out old motor cycles from my youth, in order to relive my youth.
To date I have restored a '68 Triumph Bonneville T120R, a '74 Triumph Trident T150V, and a '74 Norton Commando 850.
As I refuse to pay silly UK prices, I sourced all those bikes from the US with the help of my buddy, Dave, in Illinois.
The most expensive was £2400 + shipping - you don't have to pay over the odds.
Anyway, enough of the background rambling, and I'll cut to the chase.

With my US buddy brokering the deal, I have just bought what appears to be a very complete 1973 Honda CB750 K3.
In keeping with my philosophy of not paying too much, this venerable steed cost me a very reasonable $2000 - £1515 in my money.
I think the seller undersold, as he spent $1300 last year on carburation, ignition, front tyre, and a few other jobs.
It's a good runner, although Dave says that it has a "stumble" at high RPM - I presume he means a misfire.
It even has the original 4 into 4 exhaust system, which I believe is NLA.

It's going to take a couple of months to arrive here in the UK, so in the interim I'm going to bone up about these bikes.
I've posted a few pictures, and I'd be interested to hear what you folks think.
BTW, the paint job does resemble something from Jackson Pollock!
