Cast your eyes over this, try to see past the ghastly red frame and the finned covers, if anyone here did see or own this bike they will remember it. I found the photo the other day, while looking for a picture of my 'daylight only' Norton Atlas racer.
Its the only photo I have of the CB750 I bought from Sports Motorcyles when I was a student of 19 or so, so approximately 1976. It had, I was told, a Yoshimura cam and pistons, although I never saw inside, I had no reason to doubt Steve Wynne, and I got a good part ex on my Suzuki GT550. It was very fast, very loud, but I later sold it because it kept trying to kill me (though that may have had more to do with me being 19). I now think the Girling shocks may have been a bit on the long side, it was prone to high speed tank slappers and it had oversize TT100's which won't have helped. Also I racked up a lot of speeding points in a short time and was getting close to a totting up ban.

I have no record of the reg or VIN number, I think it was a G reg, it may have been H, so 1969 or 1970. I do remember it was sold to me as a K0, of course in those days the word 'sandcast' didn't mean anything, anyway it was just another second hand CB750 then. Looking at this list: http://www.honda-classics.co.uk/model-by-model-guide/ only 36 K0's were imported into the UK, I don't know about the original 'non K series' CB750s.
Looking at the photo I doubt it was a sandcast, as it has a finned oil filter case, and beaded edged 'non cut' mudguards. I wouldn't have known what a wrinkle tank was then, so I don't know about that. The forks have that step under the oil seal that early bikes do, I never did fix the torn gaiter. Whoever thought the red frame was a good idea also chromed the fork ears, I don't think they are later ones as the have the small reflector still. Those mirrors fix differently to the stalks to my K1. Only one throttle cable, which seems right for a K0. The white Honda badge is wrong, but a black one wouldn't have showed against the dark blue tank.
It had an oil pressure guage, you can just see where it connects to the oil gallery.
The carrier is the same type as the one I have on my K1 now, Tower I think, when you put luggage on it the front end wobble became worse, my K1 doesn't do it at all, mercifully.
Whatever it was I don't like to think what it would be worth now, though I'd put it back to standard, in any event if I'd kept it I'd probably be busy pushing up dasies by now.

It was probably an original CB750, one of the main differences about the K0 was the twin throttle cable arrangement, bet you wish you'd kept it now!

K0 oil tank, early engine possibly in the 103 range , fuel tap on the right, K0 seat but, K2 ears with K0 reflectors

I have seen H plate UK, K0's, with 101 engine numbers
-
Probable a pre-preproduction bike.
-
I have two UK units (both H plates) with 1015*** vins.
-
Cant believe that +/- 101 bikes came to Europe in those days.
-
Believe it Uli because it's true :-)....Both bikes were uk registered in Feb 1970...

Finned oilfilter is said to be introduced from E-vin1783!

Where do you get that info from?
-
Whoever rebuilt it was clearly into fins everywhere, the alternator and mission cover too, so he wouldn't have kept a bald filter cover if a finned one would fit.
A close up on the back of the pressed number plate, is that a 'G'?

Oil filter case was replaced by dealers due to a service bulletin. So that finned case does not give any evidence.
As far as I know, fin-less oil filter case was used until # 4148.
Actually, I am restoring # 1983 so it would be of great interest for me if Erling is right with # 1783 being the last engine.

Parts List says change at #4148, as does notes on differences on the Sandcastonly site at http://cb750sandcastonly.com/differences04.htm

-

interesting colour scheme,I don't remember red frame/blue tin wear , but the little Yam I am restoring also had that (fetching??)
colours.
any more info as to how it started ?
-
i remember the phase of everyone painting their frames red for some reason ? late 70's early 80's, ;) cheers Mick.
-
Red frames, wasn't that the Bimota effect?
-
The other effect was they handled. ;D
-

grins !!!
forget Koni shocks,Rickman frames, just paint them red,and ha presto !! they handle !!!!
-
At the expense of them breaking down ;D
-
Well there you go, post a 40 year old picture on here, within days you have the engine number withing a few digits, and where it was taken, yes Mick, it is Goodwood Rd, outside my mum's.
Fast forward another 20 and I have a pic taken there of a 40 foot artic, trailer full of racing cars, overnighting there on the way back from Knockhill.
I can confirm that the red paint actually made it handle worse, not better.
-
My 500 handles good with the red frame, but now I'm thinking I should paint it black and get it handling even better ;D

As for E-vin 1783 to be the first to have finned oil filter is not to say it was the last non finned!
Steve Swan of US forum claims his from new CB750 E-vin46XX had a no finned filter.
Last sunday of August '69 I saw in Sweden 2 CB750 both with finned filter. E-vin about 23XX.
Ordered one next day from Honda dealer in town for my E-vin1638.
As for knowing this exact E-vin somebody once cited a service bulletin here or in the US forum.
