There is no specific Honda manual for the K2 as the Honda one covers all the 500 and the 550 models. The K2 was a 73 model. I do have all the manuals and parts books i have on a cd/dvd

Loving your restoration posts ..keep em coming 'warts and all' please !

Luckily, the 500 manual is spot on for my restoration ...even shows the correct crankcases . The manuals I have for 500/550 are in my Dropbox link but guess you have those already

Bryan ,were there any Service Bulletins for the 500/550 like they did for the 750?

Yeah, still shows all the dirty and agonizing stuff long before the shiny and bling stages when finally done someday ;)
Wait till I brake out the angle grinder to cut and smoothen off all those "additions" some PO's welded to the frame decades ago...

Collected those in good quality (so not the Honda4Fun ones...) down to the CB550F2 supplement long before actually starting the work, and merged them into a 190 page *.pdf, which I'll choke through my duplex printer later today (hard to work from a screen on a bike, one needs to have the paper right on the bench there...).
Basically the CB500K2 seems to be a 550 with smaller engine... LH switch pod like the 750 (horn/pass combo), clutch interlock switch, the "newer" clutch design... so I'll have to be carefully when ordering parts, but thanx to your link to the parts list (also printed) I can hunt more accurately.

So, the Ricoh is ticking off the heat (and screaming for new toner  ;D)
My edition of CB500-550 w/shop is sorted and ready to get stapled (too thick for my small spiral binder)...
Think I'll keep Sundays for the more administrative parts of the project/s, like research, ordering parts, etc...

BTW: when working on the K2 I found the contacts plate to be shot...
Some ham-fisted PO managed to strip the thread for the bolt holding the right point and jammed a slotted M6 into there (which is why I'd only replaced the left one yet...)
So I had to go for a new points plate assy... another € 45,-...
Still not sure if and what electronic ignition I'd go later on...

Thanx, nice offer I will return to in the future, especially on some rare items.
Just don't know if everyone is willing to part from his stash that easily ;-)
And at this time of the year, folks might have other things on their minds...

Like my bleached and mangled pilot lights console, which has [turn - high - oil - neutral] whilst all offered come with [turn - oil - neutral - high]...  :(
Methinks such items then qualify for the [desperately seeking] columns...

Till current day only one found with "my" configuration, and that's in not so good shape...

Received the CB500 Owner's Manual today, nice read  ;D

Removed that knackered points plate, pulled advancer, freed the moving parts (yep, stuck...), lubed them, sprayed some untold liquids on the assy to stop corrosion, cleaned ignition housing (found drain hole clogged with engine sealer??), put all back together, adjusted ign timing, tested: nice, solid spark on all four.

Started toying with the one (out of four) nice looking cab bank:

Found an unusual VR made by BOSCH:

That RCA transistor alone might make it worth keeping though...  ;)

Design or air-box, resp. position of the drain seems to depend on year of MFG?

[ Guests cannot view attachments ]

The K2 utilises the lower one, stub at the LHS.
I do wonder why the engine breather isn't routed into the air-box as on current vehicles.
Would burning those gases have ill effects on the engine??

Air filter housing and lid are in bad shape:

Found a NOS housing though, still in need of lid, mesh-cover and all the metal hardware/stays it (once) was mounted to the frame...

Air breather from cam cover never went anywhere except to atmosphere as there were no emission regs when bike was built, drain from air box has a split end to allow water to drain out.

That sidepanel badge you wanted must be a european only one as the US K2 parts book I aquired shows the original type as being on the K2

Yeah, we even had leaded fuel back then...  ;)
Still, would it actually hurt to route the case vent into the air box?

Yep, the rig is a CB500K2-ED; not an F nor a G...
It even has the clutch interlock switch... interesting that all CB500 wiring diagram omit that, only shown in the 550 grid...
Sooo... which wiring harness do I need to obtain later??

If you want the interlock get a US 550 loom
