Hi guys, Heres my story of my latest find.I live in the city and my neighbor up the street had this bike sitting in front of his driveway, when I saw it my heart sunk when i saw the paint scheme, the ducktail seat and the black speedometer tach gauges. I said that looks like a cb750 sandcast! I had to know if it was forsale even if I were to get a no answer. I buzzed his door bell and he came right out of his machine shop man cave in back. He was the original owner, bought it right off the showroom floor and told himself he would never sell it

but his wife told him he was too old to ride anymore being around 70 years $:-\$ so frustrated he told me he rather see it go to a good home. He said a local tweeker had come by showing interest a month earlier and tried to start it with jumper cables using a car

and told him if he would hear it run he would buy it, the old man complied long story short the tweeker got it to fire up and offered $200 the owner said get lost. He broke the throttle cables and original airbox try to squirt either in the carbs and give gas

. a shame so I need to locate a 4-1 throttle set-up and a lower half air box that is painted to match the original. I took off the fairings that the owner had the dealer add-on since new, and the patina with dust resembles a barnfind

I am new here so I wanted to share my treasure find with you guys. I think it would be neat to leave it the way it is with the dust on the bike and ride it to start a new bike craze the "barnfind patina look"

or should I restore the bike

please comment let me know what you think. First pic is how I found it and the last is its current condition state. I was surprised not really any rust at all just light surface.The bike is safe and sound in my garage now away from any tweekers. heres a video of me talking to the owner

Welcome to the forum...great find. Sort of depends on how much money you want or have to invest. If you can restore then go for it. If not ride it like it is...or...ride it like it is until you can afford new paint, exhaust, etc. Exhaust alone will cost you around $2,000 for OEM so I hope those are as good as they look with no holes. How many mile? These bikes with minimal maintenance need little more than the basic 3,000 mile work...points, condensers, timing, valve and cam chain adjustment, carb cleaning, carb sync and tank cleaning. Then they are really good to go...let us know your plans and congrats on a great find!!!

Just saw the video...18,000 miles...unreal!!! The owner looks pretty good for 70. Consider yourself one of the few to find something like this. Treat it well and do not be in a hurry to start it up. I always want to give the bike the best chance by doing the 3,000 mile maintenance first. Then it will not let you down...Mr. Honda designed a great motor and the longevity of it is awesome...that is why we have so many guys on this board. You are at the right place as we enjoy sharing and helping each other out. Good luck with your project!!!

barnfinder welcome to the forum. What a way to become a member here with a find like this. So it is a sandcast

your one lucky son of a gun. Im happy for any member thats happens to be at the right spot and right time to come across something like this. I've been back in the sohc4 world since 2009 and I've road all over my area and then some and have never seen any type of older Honda

not one that is let alone a SC CB750 sitting out in someones drive way or yard. How long had it been sitting outside like that? Again congrats!!

I responded to your introduction post. I see a 10th bolt on the clutch cover, which tells me that's a diecast engine, not a sandcast. It could be a very early diecast, which are very sought after as well. If you give us the first few digits of the frame and engine numbers we can tell you exactly what you've got. It's still a great find no matter what!

How much did you get it for? What is the serial number ? Don't need last two numbers..
I too found #572 in a barn. About 16 years back..

dhall57 · « **Reply #6 on:** October 13, 2014, 12:18:21 PM »

Agree. Great find either way. SC or diecast

Tews19 · « **Reply #7 on:** October 13, 2014, 01:18:53 PM »

Nice find and welcome to the site. Curious if that if that's a low number Sandie? The ignition is in the wrong place and incorrect. Maybe the bike is an import and that is where the red speed indicator was located at one time?

Johnie · « **Reply #8 on:** October 13, 2014, 02:09:44 PM »

As long as you are getting some numbers so we can help you identify it, take a look at the black and silver ID on the right side of the steering neck (part of the frame). There will be a ID number on there and also a date and year (10/69) which will tell you the month and year the bike was built. Agree with the guys...sandcast or die cast she is a great bike for you.

Nice find and story.

If it turns out to be a sandcast, you may just arrest the rust and clear over it (keeping the patina). There's nothing keeping you from doing a full resto down the road, and it might have better value as an original bike.

754 · « **Reply #10 on:** October 13, 2014, 03:31:20 PM »

I think all diecast had the tag, i know the real early bikes did not .

Congrats. Doesnt look like it needs restoring, just clean clean clean it. They are only original once and highly sought after in original cond.

Fun story, old Hondas can turn up anywhere, anytime. One thing I see is a replacement bolt probably in the upper triple tree. Be sure the spacer is in the gap there when you finish removing that fairing bracket and tighten things back down.
I am interested in the frame and engine numbers also.

setdog · « **Reply #13 on:** October 13, 2014, 07:07:25 PM »

I wouldnt change much at all. preserve it, if its in good enough condition you dont have to restore it. that patina itself is antique. but some things will have to be replaced for safety's sake if you plan to ride it at all.

Heres why i would preserve rather than restore. It will stand out.

http://www.motortrend.com/features/112_0704_1964_shelby_cobra_289/

some fella found a barn fresh shelby cobra 289, and while he made repairs, he left it unrestored. its now a pretty famous little
cobra with the eloquent nickname "Dirtbag".

i like the patina, but i would probably look to get rid of the mold and some tannin from the rust, but not at the expense of ruining a part.

if you replace the tires, save them. You can always remove parts that are more prone breaking or wearing out, already thrashed etc and find period correct replacements in order to save the originals.

Need more detailed pics of your find and vin#'s barnfinder

Also just noticed the front fender having the cut edge only on the bottom. My front fender on my 4/70 KO is the same way. So maybe this bike is closer to my bikes build date than say Johnie's low number KO with build date of 10/69 that has the double cut front fender.

Must be one of those uber rare no number models.

Tews19 · « **Reply #16 on:** October 15, 2014, 06:40:41 AM »

Eric I think he realized it's not a Sandcast. His tag states owner of several Hondas to include a 70.

Wouldn't that be a huge letdown? You buy what you believe to be a Sandie and then turns out it isn't.

It would be a huge let down. But I'm thinking he got the bike for peanuts and that is still a great find. You only get original patina once! Plus I think he has some knowledge of Sandies with his CB collection and his video he shot with the original owner.

Great find none the less! Now how about a few pics of her after a cleaning and possibly a video of her running!

dhall57 · « **Reply #19 on:** October 15, 2014, 06:58:30 AM »

I know I would be dissappointed and PO at myself thinking I had purchase a rare original sandcast bike and it turns out its not. Just shows do your homework and check vin#"s, etc, etc. But like its already been stated, still a great find. I could only be so lucky to drive by a house and a bike like his sitting out in the driveway.

ekpent · « **Reply #20 on:** October 15, 2014, 07:06:43 AM »

No reason to be let down as mentioned. Hope he comes back and shares more because as we all know the fairly stock found K0 bikes do not show up at your door everyday and have a strong market value nowadays. Be interesting to see if it has a wrinkle tank, pipe #s etc. I would be a happy camper to find one !!

dhall57 · « **Reply #21 on:** October 15, 2014, 07:22:15 AM »

You've still got a rare bike Barnfinder. Members here just would like to see more pictures and more info on bike. I know I wish it had been me that found it

HondaCBarnfinder · « **Reply #22 on:** October 15, 2014, 10:06:46 AM »

I will keep you updated with the progress of the bike, I have not started the bike yet as the throttle cable is snapped. I think like you were saying do the 3000 mile tune-up would be good first,clean carbs , points ,battery,tank ect. I paid a little over a grand for the bike and had to file for lost title since the original owner could not find it

I remember the sandcast 750's had the black gauges and this one does also it had the ignition switch down under the tank what he described to me as the push-turn ignition that the sandcast bikes had but the owner said it stopped working and he moved a aftermarket one to the top tree since it was the thing to do back then with fairings. From what I'm finding the bike is identical to the sandcast, I looked under the tank I didn't see any wrinkles tho

so mabey diecast? the vin tag says 6/70 cb750-1041455

goldarrow · « **Reply #23 on:** October 15, 2014, 10:27:08 AM »

That's a late K0

Greggo · « **Reply #24 on:** October 15, 2014, 10:58:51 AM »

Great price for that bike, even without a title. Are the pipes rusty on the bottom? Do they have numbers stamped into them like HM300?
