G'Day,

started an introduction at http://forums.sohc4.net/index.php?topic=87935.0 and got loured by SteveD 

Bought two CB500/4s recently and will start refurb/rebuild in a couple of weeks, gonna be on a parts-chase then...

Also unclear yet what colour sheme the EC spec bikes (if there has been such back then) did have

Previews of the mess I trew my money on 





(no, them boats where not included...)

[Bryanj]

EC colours were same as everywhere else, PM me the frame numbers and i will give you an aproximate build date plus choice of colours

Hello and welcome to the forum.

They'll keep you busy for a while but look to be mostly there. Curious disc arrangement you seem to have a twin disc setup but spread across two bikes that I've not seen before.

Also the one with the fairing appears to have a Yoshimura pattern to the downpipes that may be period mods.

Welcome to the forums, they certainly look ripe for a little TLC, have fun.

Cheers

Hi and welcome, are you restoring to standard or making something special?

Hi and thanx!

the one w/out fairing and the 4x4 is a '76 I plan to refurb to OEM condition, and sell to a caring owner...
Besides the 'rippled' ignition- and clutch-covers it has those aluminum-bed rims with 'collars'
Dunno yet if I should leave the 'M-style' bar on it, I tend to get the OEM touring handlebar for it.
Frame No. 2083333
Engine No. 2169911
(seems to be a K1 frame with a K2 engine then?)
It also has the fork-bottoms for fixing two caliper/arms, which I'd like to nick off and rebuild it to OEM LHS single disk.
The red tank on it is finished... like a noodle filter... you can brake through with your fingernails... was stored bone dry...
But its the blue tank on the other one that belongs to it anyway, which is in good shape so far (will see once we get the numberless layers of paint off...)


The one with this Tomaselli(??) bikini-fairing (that thing is tucked on with HILTI band...   ) is a '73 and has a 'special title' issued '78 by the dept of automotive and transportation, 'legalizing' the Marving 4-1, intake bellmouths (no filters or mesh... now that's gonna be fun with them cops...   ), rear-sets and clip-on handles. (is also has a shorter(!) swing-arm from a post '85 CB installed... )
That one is a keeper (for that title allone) I plan to 'cafe', would like to get a shiny aluminum tank (not narrowed as I already knock my shins on the valve covers and carbs...) and tail-cone, flat upper tripple-clamp, place the instruments lower and more horizontal (K0 clocks with the embedded idiot lights would be great...), get dual disks on it (probably need to swap the (shorter?) hub and speedo drive from the '76 as well), etc...
Frame No. 2016197
Engine No. 2016202
seems to be a true K1 then

Those are the b/w pics stapled into its 'special title':





Technically I will have to stay close to this to pass the MOT, seat and tank are not soo critical there, but I'll have to see if I get away with the twin-disk setup then (I think a CX500 MC & lever should match nicely with the CB's clutch lever)

Engines on both look dry and rotating (pumping the kick by hand), will check compression and visuals of exhaust ports to determine of both require rebuild.

Wirings are the usual mess, electrical tape, etc... plant to equip both with electronic ignition however.

Lots of work, lots to be organized, lots of 'fancy language' gonna be used, frames to be sanded and repainted, but I think the whole project is going to be lots of fun.

Haven't started yet, as I'm currently re-furbing a '94 ST1100 with >190.000km on the clock (technically +A but got vandalized, kicked over, etc... dumbasses...   ),
but already stretching out on parts sources, ideas and tips  

[Bryanj]

2016197 SHOULD have been built about March 72 the 76 is still a K1 even though the frame number is high as Honda were building K2 for the US; 550 K0 for the US and K1 for europe and UK all at the same time!!

[ST1100]

Thanx Bryanj,

the docs only show the date the vehicle received its first registration, not how long it was on stock at the importer.

Any objections on removing the dual disk fork-bottoms from the '76 to use them on the 'cafe'?
I don't think that model/year ever came with dual disks and also the dimensional drawing inside the title (which is a little booklet) shows only one at LHS.

Any other do's and don'ts to observe?
Any hints are highly welcomed, before we start to work into a wrong direction and have to tear down anything.

[Bryanj]

They are probably from a 550 so no problem at all with the swop as long as you keep all the internals with the steel legs due to variations

[ST1100]

Certainly will swap the complete fork legs and check everything bit by bit during the rebuild/overhaul, who knows how they have been messed with over the generations...  
W/shop manuals (both, 500 and 550) are already downloaded and get studdied carefully...

When even on a '94 ST, which was serviced regularly at a workshop(!), bolts have been mixed, replaced with 'any' style, or rounded off, will there be no end to the WTF about incompetent tinkering on them CBs... (already spotted slotted bolts holding the valve covers and such...  
I'm already prepared to find things like electrical tape or plastic plumbing pipes inside them forks...  

But I think everyone around here probably went though such findings during his rebuilds...

[ST1100]

G'Day again...
And apologizes for going mute... 

After 3 years a friend and I f i n a l l y managed to find a small, affordable workshop space... 
Currently busy collecting all our stuff from various locations and hauling it into the new burrow...
Will take some time and work till fully operational, but I do have a permanent home for the vintage SOHC bikes now...

cheers!

Is this a record?

 

Welcome back.

Start a project thread as we now have a special area for these.

[ST1100]

Is this a record?

LOL! Probably... 

Anyway, the FOB is operational! 

First official tasks:
- replaced rear wheel bearings and seal on my '00 ST1100 (as seen in avatar)

- helped my friend/co-tenant to revive his '79 Z750



After 15 years grounding it suffers issues like seized callipers and such...

Once that's a roller with MOT I'll start knocking the CB500/4s apart... and be annoying with all sorts of questions in a dedicated build/project thread 

[JamesH]

Cool. Speak to you in 2019 then :-)...

[ST1100]

Cool. Speak to you in 2019 then :-)...

LOL! 
No, I seriously hope to have a continuous attachment to them two bikes now...

And, having that workshop space now is really great!
