Topic: 1970 CB750 K0 found in a field. Restoration.

[Honda Tom]

Okay boys and girls, here we go. I have been waiting for this project for fifty years. In 1971 I bought a brand new CB350 from Warren Wilson Honda in Sepulved CA. I drooled over the CB750, but could only afford the CB350. ($829.989). Flash forward to now.  Down the street from my brother-in-law's house, in a field, I spotted what looked like a CB750. WTH, who would park a CB750 in the dirt and grass. Two years went by, (I don't visit much), Honda still there. I took some pictures in the dark, and thought the engine numbers were in the 4,000 range. WOW a sand-cast bike. Upon a closer look, the engine number was in the 40,000 range. Born in June 1970, still not bad.  I left a note on the door, asking for information on the Honda CB750. Nothing for months. I finally get a call, "I need to move and cannot take the Honda with me, are you interested"?? Well, heck ya!!! The owner said "make me an offer". I told him $500 would be a great deal for me, but $1,000 is probably fair. Now the 1970 K0 CB750 is mine. Now what. A closer look shows engine will not turn over. I can deal with that, as I expect an entire engine rebuild. The gas tank has major rust and seam dings, probably not usable. Everything is either rusted of corroded. Okay, you got it. I still think this 1970 CB750 is worth a FULL restoration, and put on the road AGAIN. NOW WHAT...I need help with...Where do I find this....How do I fix this....What the heck is this..... I plan on attaching tons of pictures to document this project....  One of my first questions is the kickstand. Not there. Can this be replaced or fixed. The rest of the frame seams to be okay, other than light surface rust and corrosion. Thank You!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!1111

The first picture is what i'm shooting for.

[BPellerine]

it has a lot of hard to find parts on it,so you are ahead of the game in that way,an oiltank and a couple of other parts would cost what you got the bike for,if you could even find them.bill

[BenelliSEI]

They all cost about the same to restore. With a K0 you might even break (if you value your time at$5/hr., and do most of it yourself). Nice project, all the best!

A full resto will be costly but what the heck else do you have to spend money on!?  Many of the oxidized parts can be refurbished by vapor blasting.

[BPellerine]

and yes the sidestand can be repaired,weld a new one on.

You'd be suprised how much better she will look after soap, water and 0000 steel wool.  Mine was in a shed for 26 years.  You may want to go with a patina rebuid after you do the engine.  Then attack each item one at a time and don't keep the bills.

Thanks for the replies. Fortunately, I can do all of the nuts and bolts work myself. During the 70's & 80's I did a lot of motorcycle and car rebuilds and repairs. Engine and transmissions, etc. I plan on using as many NOS parts as I can find and afford. I watched the entire "Hack A Week" series that HE did on his 1973 CB750. Lots of good information from Dino.
Three questions:
1. I have a Honda Shop Manual, dated 1970 and My CB750 Book, by Mark Paris. What other books or manuals would you suggest I have on hand for my project?
2. Back to the kick stand. Where or who would I get the frame parts, spring, and kickstand from. Would that have to be welded and aligned with the exhaust on the bike to ensure proper placement?
3. NOS and re-pop parts suppliers?
Thanks, I'll be back, hopefully with some pictures and progress.

Be careful with the kickstand repair, it can be done but you want to be careful.
 Wether you can keep what's left on there or not is the question right now.

  Exactly 754. I don't think this is as easy as slapping on a new kick stand. I know it can be done, but a lot has to be take into consideration, position, angle, etc. I am thinking the best solution is to find a donor frame, cut out a section that includes the kick stand, and weld that section back in at the correct location and angles. With all the experts in this field, I am hoping for expert advice with this problem. I have been reluctant to start this project with this question in mind. If this can be solve without making me go crazy, I will spend the money to make this old gal KO purr again. I have to wonder, what happened to the original kick stand??

[BPellerine]

people sit on them with the stand down,and some kick start them with the stand down

  I get it. That would put a lot of stress on that. Sooooo, now what?

[MauiK3]

What’s the engine number?

Yes I agree. If this old gal had some attractive patine (check the picture), i would go for that. Since I am tearing this beauty down to every nut and bolt, I'll do it once and right the first time. And yes, don't tell the wife of the $$$$$$$$$$$$$$$$$$$$.

The pic you just showed is not a 69 or 70 top end.,
 The bike with Jerked is not what you bought.. correct ?

No, No No, Just a picture of a cb with a lot of 70's patina and graphics. Mine is a blue ko 1970.  This is my 1970 CB750.

Looks like it has the same jardine pipes my 750 came with! I'll be excited to see your progress!
