Time flies when you're having fun, and it's time for an update.
I continue to lurk on this site, adding to my knowledge base for CB750s.
I finished my K0 last summer, and spent the season riding and tweaking it as I got familiar with it.
The weakest part on the bike now is the pipes. They're original no-number pipes, and unfortunately the bike has been down on it's left and right side sometime in the past. So there's a little damage to all of them... but from 20 feet it's hard to see.
I'm struggling with a "grabby" clutch once the bike is warm, but will continue to work on that issue over the summer.
Here's the 99% finished product.
Thanks to all of the members of the forum... you've helped directly and indirectly on this bike.
Regards,
Mike

Time for a reintroduction/update.
Based on the feedback from my first post, and a review of all of the missing parts from the first bike, we decided to look for a more complete 750 for restoration.
The local Honda dealer had taken a early '69 in for trade-in on a generator, and offered it to us.
The serial number is 117xx... a relatively early diecast bike; virtually complete, and with quite a few NOS and used spares.
What I like about the bike is that it shares some of the same unique parts as the sandcasts, and that's why I've lurked in the background... and will continue to learn from the previous experiences of you fine folks. Thanks to those who've already contributed to my restoration!
So far I have a double-cut front fender, double-rolled rear wheel, 2-hole rear hub and no-number exhausts.
So long story short, thanks for your help to date.
Mike

4pots1969 and kp,
In summary, and correct me if I'm wrong; in your opinion, if the guts of the engine are sandcast, then there could be some value there. Otherwise, the engine is an oddity but nothing special.

UK Pete,
I believe this is the path we will take.

All,
I'm probably 6 months away from starting this restoration, so I've got time to consider frame VINs, engine VINs, etc. We're collecting as much early CB750 parts as we can, with the hopes of having a '69 in our stable. We'll see what the next few months bring!

Thanks for your input,
Mike

So is there anything particularly special/unique about the motor, considering the low SN and the error?

Thanks,
Mike

KP and Pete,
Thanks for the welcome to the forum.

KP,
We understood that it was the dealers who stamped the replacement engine, and that is likely where the error was made.

We are very clear that this isn't a sandcast, but at the same time we hope to create the "earliest" CB750 that we can. My father has a '71, and it also looks like he's getting a '74... so we're starting to build a small stable of CB750s!

Hello Folks,
I'm Mike, and I live in Western Canada.
My father and I have acquired, what we think, is a fairly unique engine.
The serial number is CB750-1000767. Note that there is no "E" in the serial number.
Further, this is not a sandcast engine (unfortunately). It appears to be a very early die-cast engine.

We were told by the previous owner that it was a warranty replacement for a failed sandcast engine.

Our intention is to restore a bike that is as early a 69/70 CB750 as possible, including as much sandcast hardware as we can.
The original frame is gone, but we've acquired the earliest frame that we can; CB750-1016086.

So first, I'd like ask the group about the "uniqueness" of the engine.
Second, anybody got a frame that's close to 1000767, that they're willing to part with?

Thanks in advance,
Mike
