Topic: another ID query

[petercb750]

Hi all.
A friend here in Oz has just picked up a pretty ratty SOHC that from his pics looks like an F2 (comstars, tacho redline at 9200 or thereabouts, mostly black engine ie what can be seen thru the crud), and the engine # is CB750E2613423 which would confirm it as an F2 engine, yes??
However, he has sent me the frame # to help him identify what he's got and he tells me it's CB750G1006044 - now that doesn't relate to anything in any of my books, other than it possibly being an early K frame, but the G has got me beat. It is plated 11/77, also confirming it as an F2? (Of course, plate may have been swapped in its dark past!)
Anybody able to throw some light on this G bit?
Thanks
peter.

Dave silver told me the "G" was the F2 imported to UK but maybe some went to OZ. Some people tell me the engine should be CB750FE ***** but have no confirmation or proof of that

Yeh Bryan - just rechecked my books and in one of them the eng # is listed as FE for F2s, so will get my mate to recheck that too on the bike. Thanks for the info on the G - interesting, you never know, this one might have been imported to here from UK some time in its life.
I know from what I've read in books and on these boards that the numbers tended to vary a lot from country to country, so maybe somebody else will know if the G came into Oz ex Japan.
I reckon we're pretty safe in naming this one a real F2 - what d'ya reckon??
Thanks for the efforts.
Peter.

As far as engine goes the only 100% safe way to ID is strip it and look for the differences, E.G. domed pistons, valve head diameter etc., ask MReik for all the differences as black colour dont mean squat. If the frame is a "G" its an F2 no matter where it was originally sold

Does anyone have a list of the engine and frame numbers for the CB750F for areas other than North America?  I have this information for the K bikes listed on the website, but I do not have the same information for the F bikes.

[petercb750]

Glenn - in one of my books, "Honda CB750" by Mick Duckworth, which from what I can tell is pretty well all British info, it lists the following:

CB750F Jan-Feb 1975
frame from 100.00.02
engine from 250.00.04
total 15000

CB750F1 Mar75-Nov76
frame from 200.00.03
engine from 251.50.94
total 44000

CB750F2 Nov76-May77
frame from 210.00.11
engine from 260.00.04
total 25000

CB750F3 May77-May78
frame from 220.00.01
engine from 310.00.01
total 18400

I note in this book the Fs don't get an E prefix for the engine #, but the Ks listed do. Bryan has said earlier that in fact the F2 should have the prefix FE, which another book of mine agrees with (The Complete Story, Mark Haycock). Might just be an oversight in the Duckworth book? The frame #s listed don't correspond with the frame # on my mate's bike, hence my original posting. And Bryan suggests that the G was for British, and maybe Oz. Seems to me that there are no real consistencies, which I've heard and read about Honda back in "our" days.

I don't remember there being an F3 here in Oz (but it was long time ago and there's been a fair bit of water (and beer  ) under the bridge since then) so maybe all we had here was a continuation of the F2, just like we had the K2 run for several years.

Anyway mate, hope that helps to answer your query.
Cheers
Peter.

I have a "G" model (general export) model F2 - frame number CB750G 1012524 - originally imported (privately) to NZ from Singapore of all places... the Honda distributor here did not import the F2's, only the F0 and F1. I guess there were the North American models, the European ones and then the "rest of the world", the "G" versions...

I had the same confusion over what I actually had too, as this site, nor any others I could find, ever mentioned the "G" in any frame numbers anywhere... also there is no F in the engine number either, just simply CB750E 2614968, yet there are all the hallmarks of the "F" engine - black with additional fins on crankcase, larger fins on oil pan, an "oil cooler" - finned plate between oil filter case and engine. Final drive 15/43 or 14/43. I've decided that I have a '78 F2! 

I think I read somewhere (probably on this forum in a topic!) that the G model was the one imported to Oz back in the day....

Cheers, Phil

Mate - thanks for that. Your engine # is quite close to my mate's also without the F, and the frame # has the G.
That's bloody good enough for me too - I now proclaim that he is the proud new dad of a late 77 F2, engine # just 1500 or so earlier than yours, and frame # about 6500 earlier.

Cheers!

    There is no F in the engine # here in the states either. This may be a typo made loooong ago that kept being repeated

No worries - you're welcome. I've been thinking that the "G" model was sort of cobbled together with left over frames and engines, as the disparity between the frame and engine numbers seems to be quite vast in a lot of cases! Oh, and it was David Silver Spares (when I e-mailed them) who "confirmed" that I had a '78 general export model, which was good enough for me... although it could quite easily be a "77 I guess - bit of a grey area really...

Cheers, Phil

Well then, Glenn? - there needs to be a change in the info on the sohc4 site maybe?

Cheers, Phil

According to the US ID guide book all the "F"'s from 75-78(but not the "K"'s) should have an engine number CB750FE BUT I have several 750 bottom ends,all 750 from 75-76 and NONE of them are FE just E-- then again I am in UK
