Just found me a real live 69 CB750 Sandcast.   I have run an add on CL non stop for the better part of 5 years.  Most times, people flag it, but every now and then I get a hit.   I've found all 5 of my previous projects on CL.    Last week I had a guy email me and tell me he had a 73 CB750A.   I emailed back and told him I probably wasn't interested (since I thought it was an A) but to go ahead and send me some photos.   Imagine my surprise when I saw what appeared to be an early CB.   I picked up the phone and tried to get more out of him.  He's an old retired hot rod guy and was a lot of fun.  I told him I didn't think it was a '73 but I was very interested anyway.  Had him take a look at the serial numbers.  Oh my,  the frame was a sandcast.  Most of the parts looked like a sandcast.   However, the motor fell in the 8000 range, so I figured it had been replaced at some point.   I still had to have it.

Went down and looked today, and imagine my surprise when I discovered that he had misread the serial number off the engine !!!   I frickin' found a sancast.

Now, since I work for the notoriously cheap University of North Texas, I will have to do the restoration on a very strict budget.   Luckily, I can do all the engine, electrical, and paint and body work.   I won't have to pay for any labor - only parts.   It is my intention to do a complete tear down and rebuild.    Every nut, every bolt.   I will re-use everything that is there - trying to keep the parts original to the bike in place.

The biggest pain will be finding a reputable plater for the nuts and bolts.   The biggest expense will be the exhaust.    Wish me luck.   I will be documenting every penny I spend on this beast with the hope of keeping the total money spent under $3500.  That number is pretty ambitious, and hopefully i will be able to stay under it.    I won't count my labor - it fun and free.   I'm not going to count beer money either.

Wish me luck.   Probably take me the better part of the winter to accumulate the parts I will need.

Luckily,  the only thing that I can see that is msising are the mirrors .  Everything else seems to be there in the boxes he gave me.   He also gave me some extra parts of a later model F that I will be selling to help buy stuff I need.

Congratulations on a remarkable find!  ;)  See if you can locate a copy of the John Wyatt book as it has tons of detailed info and photos about the Sandy's. Especially helpful is the frame & engine production changes by serial number.

Congratulations on your find and you have a great plan to restore the bike too!
Check out Yamiya online for authentic  Honda parts.

Then there is that guy online who hoarded all those parts from all the  1400 dealerships. He probably wont help you though. You can always ask.

I'm sure that when that book was published (1998) it was a valuable resource.
However, most, if not all, of the information in that book is now available from other sources on the web.
Because of that, imho, the book isn't worth the prices it's commanding now.

It’s good to know that in your opinion the book is not worth it.

I'll sell you my copy for a mere $200.  ;)

Fwiw, I don't think the photography in the book is very good either.

Now - someone has to have a connection to a plater...anyone ?

DFW area would be even better.

Talk to KingCustomCycles, I think I remember him saying his brother is a plater, or maybe it was Franken?

At least those carbs will not be a problem like the modern carbs would.
Those cabs are VERY simple and efficicent. Easy to work on and understand.

I hear it's syncing them that is a problem.

Why plate the hardware, that would not be original? Replacing the hardware with stainless would be the way to go if you are not doing a concours restore.

Good luck, what a great investment!

I think that just cleaning up original is the way to go. I would rather see a bike that seems to have survived 40 years unmolested rather than a harware store restoration. There is a certain honesty that a little rust here and there will carry.

Like all of those brass antiques that you see that were polished and over cleaned....killing all value.

Replating all those rusty, corroded nuts and bolts is the way to go.
Even if you laboriously clean every one they will just rust again later.
Imho, ANY original part you replace will lessen the eventual value of the bike.

If you're really serious about it it's right way to go.
You can do it yourself relatively cheaply.
