Topic: So , i found what i'm thinking is a K0, but any info would help

[Thunder]

Hi guys

Whist rooting around in the depth of the classifieds ,this popped up...
It was advertised only as a '69 Honda.
If i am reading the numbers right she is a fairly early diecast?
(here's hoping)

But she has been very abused, but surprisingly she looks kinda ok in the photo's.
A front end accident years ago required the PO changing the forks etc.

Actually the guys i got it from had done a pressure wash so she didn't leak oil whilst we were looking at her, lol.
but once back at the barn.... she leaks ... alot.
Anyway im thinking a top end strip down at the least...

Please note the desirable machinery in the background are not mine, but belong to a mate.
(and they are immaculate)

A few things i would like to check with you guys...

Oil tank is different from the other K's I've seen, but I'm assuming this ties in with the larger stick-out sidecovers (louvered ones).

Is there any way to confirm this is a 69 model?

Would this one have had the plastic clocks?

Pipes would be the HM300's?

Battery holder would have the smaller holes?

Forks, these are the ones with the 2 holes on a ridge on the front of the forks as opposed to the offset individual protrusions of the later years?(sounds garbled, so i hope you know what i mean)?

Will i need to get the duck seat?
The headlight, are the colored headlights the same shape as the later black ones?
Plastic chainguard?

Would this have had the "Wrinkle" tank?

I have a set of fork ears and sidecovers. (yay, i have 2 thing out of an ever growing list, Lol)

Anything else i should check
Anything that you pick up from the photo's ?



cheers and thanks so much
Thor

Mine was built 11/69 and it's serial # starts with 101 so, yes it's a built in  69 diecast and should have a wrinkle tank, early forks etc, It could be licensed as a 70 though. I'm not positive.

[ekpent]

Oil tank looks early,the pipes on one that early may have been a no stamp but if not then HM300's. Yes the gauges would of had plastic faces and there would have been a ducktail seat and wrinkle tank. It would of had the elusive shorty plastic chain guard and the headlight buckets are basically the same with the early ones painted along with painted fork ears. Can't tell what the forks are from almost look F model with a different disc and rear caliper mount. Carbs would of had the 4 cable set up,yours look later as well as the airbox. If your doing a restore better start saving up your lunch money

Just build a diecast hotrod, save a bunch of money but still have a rare 69 cb750..

[Thunder]

Cheers for the help gentlemen

Ok so basically Christmas is cancelled for the next few years...

I have some of the parts needed (Hm 300 pipes), clock internals.
I see one can now get the clock bodies, i have internals and faces.
Got sidecovers

All of these need serious refurbishment, but that's cool.

So in the "keep an eye out for list:

money
Lower forks
Carbs
Seat

Tx again

Someone really tried to "cool" this thing up in the past. Agree with the other fellas. Plus, headlight bucket looks aftermarket, someone changed out the rear shocks, should not be the wrap around grab rail on the KO just a small handle on left rear. Need OEM handlebars, probably bar switches, no dash lights on the KO as they would be in the gauges, your rear blinkers are mounted on the garb bar...KO was mounted to the frame via bracket. Yes, duckbill seat would be correct on the KO, but a K1 seat would work. Looks like a costly project, but I say go for it. Those KO parts are not cheap, but there are some repo stuff out there like side covers. Good luck with your project and let us know how you come out.

[Greggo]

A VIN that early would have had the 'no number' pipes, but HM300's will do just as well, and if you go with ones you already have you save about $2K on your project.  Also, that would have been a '69 production date bike...not sure which month, but probably October or November maybe?

Nice find. 

[Terry in Australia]

Excellent find Thor, mine is a 1019XXX number and I think it was built in November 1969, so yours must be way earlier than that. Unless you want to spend silly money on "Unobtainium" parts that won't add a lot of value to a diecast K0, consider Franks suggestion, build a cool K0 Cafe Racer, I think that's what I'll do. Cheers, Terry.

[camelman]

Mine was 9800 or so and was a 69 diecast. Turns out the japanese are paying very high prices for four digit VIN 750 K0s.  Nice find and i hope you can keep it.

Yeah, the japanese.
 My last Cb (74) i stuck on gumtree after riding a modern bike and deciding i needed something new.
I had a guy from japan ring me up and got his agent here in South Africa to come around and  buy it.(there's apparently a roaring trade in mini coopers as well)

Regretted it ever since. Sure i had a new bike, but i didn't build it.

As for hotrodding it... i got an F (78) that i'm doing that to, lol

So i think I'm gonna get the engine right (top end service...possibly rings, strengthened head bolts, and whatever looks dodgy.Then respray the frame and engine put a set of HM300's on her
(thankfully i got an OK set) , louvered sidecovers (have em) ,forks(have correct set) and get it on the road.

then as years/money allows upgrade with the correct pieces as i find em.
(terry , don't forget those pics of the K0 differences please)

Thanks Guys

The carbs on the bike in the top photo are NOT 1969 or 1970 carbs.

A used set is at least $600.00

Good luck with your $7000. dollar project.

[Greggo]

A used set is at least $600.00

A decent set can be had for $200-$400 on ebay lately.

[Terry in Australia]

Yep, I paid around 300 for mine Greggo, and they were mint! Cheers, Terry.

[Tews19]

I recently sold my set for 300

[754]

I had a set on here for two hundred a few years ago, that did not sell .

Tx mate,
Very possibly...i think she's gonna cost a bit
but there is nothing better than rooting around for parts (be it on the net/junkyards/conversations with enthusiasts) and coming across that part you need.
 reckon if i won the lottery this wouldn't be as much fun

Thats good.

Some carbs are being sold as 1969-70 carbs but they are not!!
The 1969-70 carbs DO NOT have lifter arms.

Still need fork lowers?

[Thunder]

Thanks man

Carbs are do-able sometime this year (kinda budgeted for em in my head when i bought it).

Steve_o,  thanks but i found a set in the shed, that actually look pretty good once i clean em up, good thing is there isn't any rust on the chrome.

Other big thing is airbox, but DSS had replica's for about 90 pounds.

http://www.davidsilverspares.co.uk/CB750K0-FOUR-1969-1970-USA/part_168491/

And here's where im at:

Headlight ears                 check
Sidecovers                   check
Carbs                          will get
airbox                          repo
forks                            check
Clocks                         The big one will wait and think what i'm gonna do here (reckoning about 6-700 dollars which is alot)
plastic chain guard      Might substitute with metal until one comes up
front caliper                 i gotta check as i got a box of calipers...(will google what the K0 one looks like.)
Switchgear?                Black off switch? I think i had one around... mebbe.

So a rebuild (not a full restore for a while yet) looks like it might be possible.

But I'm not expecting it done anytime soon, I'm still busy with a whole lot. Just finished a Duc monster that i wanted to quick sell to fund the Cb's, but it ain't moving.
Busy trying to finish a 78 cafe , a 73 and a 350F, but want to get the K0 stuff separated and packed away safely so i don't (through inexperience) use a K0 part on one of em.
(the one that regretted selling had K0 forks on it... eish...learning curve)

Thanks for the info

Oh yeah and seat , Again DSS, 125 pounds..

Ok, had a quick check between a K0 and K4 caliper....

they look the same...

And today i took some photo's of some odds and ends which i don't recognize...(i am kinda familiar with the '72 up, so if anybody recognizes anything it will help.
The one front hub has four mount holes for the disk?
the side stand? K0?

Last one is switches i was going to use on the cafe, but they look early, and i have a set unpolished, in black?
No kill switch?

cheers
Thor

[Tews19]

They will look the same but the number on bottom will be different. . I have the K0 caliper and mounting bracket and fork lowers if you are interested.

Might be, but i at the moment , i'm just looking to organise what i need and what i have.
Interesting about the numbers, Tx.
Do most of the parts have these stamped, and i'm assuming K0 (for instance would be the number 0?)

[Terry in Australia]

G'Day Thor, firstly, sorry I didn't take any pics of my K0 bits over the weekend, I had to install a water pump in my Subaru on Saturday, and I intended to do it yesterday, but I had problems with it overheating and spent all Sunday farting around with it.

Anyway, your pics of your gauges are a bit hard to see, but the complete-ish gauge (if it has a plastic top case) might be K0, the sidestand is K0 (Japan only, the Japs only have short legs) and the switch with the clutch lever might be as well. Everything else is not K0.

You can buy a good repro "shorty" chain guard from Yamiya in Japan, in fact they have just about everything you need, including a much better seat than the DSS one. Sadly I'm gonna be away from home again from tomorrow, so I won't be able to take any pics for you until next weekend, I'm sorry. Cheers, Terry.
