Newbie from Somerset with 750 K3
« on: March 23, 2019, 11:06:39 AM »
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!

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.

My US K2 doesn't have the headlight on all the time? Not sure that's correct information.

PS. Will Dave be my buddy too?

Trigger, i think it was 73/4:that the yanks made headlight on compulsory but it will, of course, depend on vin plate build date.
As to headlamp dip all the ones i have done that were not H4 converted had a straight up and down dip so same for rh and lh drive, a lot of US ones have sealed beams and if a car replacement has been fitted that would be out the window!!

There is one bolt on the Honda that will respond well to Whitworth socket and that is the original 12mm headed oil filter bolt that you can "hammer fit" a whitworth 12 point socket onto when it gets rounded and it will undo!!!
