Project Board / Re: Teds new project a CB500 K0 or K1 circa 1972.
« on: November 28, 2022, 02:06:56 AM »
Whilst Julie is 100% right in pointing out that the biggest difference between the K0 and K1 was the seat lock I’m not sure if the K1 seat lock bracket wouldn’t also fit the K0 and vice versa. There is a slight change in the part number for the frame from 130B to 140B but whether the difference was in the positioning of the holes for that bracket or something else I couldn’t say.

My comment wasn’t meant to criticise the frame, it was to ask why when the title says K1 is it wearing a K0 frame, seemed odd. I’d imagine an 8/71 build date would also mean it’s a K0 rather than a K1.

It seems that K0 models are worth more as well, so a set of K0 cases may increase its value, need an engine number beginning with a 1 though Ted. The K1 engines all began with a 2. Strangely the K2 didn’t start with a 3, which you think would be the case. Both my K1 bikes have frames and engine numbers beginning with a 2 and the L reg bike has a build date of 5/72, so your frame being much earlier than that must mean a K0.

It’s not important as you say though, it’s just odd.

I had 2 sets of engine cases spare from way back in the 70-80s and both began with a 1, which is very odd as I never had or broke a K0 but I did buy quite a lot of broken engines back then but how they both ended up coming from a model that was never officially imported into the UK is strange.

I still have a set spare if you ever want to make the bike into a K0.

AFAIK the K1 had the frames and engine numbers starting with a 2 not a 1 which was how you could tell from the K0 version. It's possible it's had a new frame fitted at some point OR it could have had a K0 frame fitted by the factory but I'm doubtful about that, the frames were essentially the same so it's not a big issue, just a curiosity. Have you checked the frame itself for the stamped number on the headstock? to make sure they match.

That cost me about £140 in 2010 IIRC, it was done at CamCoat in Warrington but your local ceramic coater should also be able to do that. Admittedly my headers weren't as bad as yours and they did sort of complain about the fact they couldn't split the pipes but they did a decent job.

Maybe pop into your local ceramic coater and see if they have any samples of how it looks, it's not a dull finish but not as bright as chrome but I'd say unless you stood right by the bike you'd not notice the difference.

Same pipes, about 18 months later, taken in December after running the bike through the winter, the dull coating is road dirt, this was taken when the bike was recovered after the accident. Bike hadn't been cleaned for weeks. The inner pipe shows the finish better as I think someone cleaned some dirt off it when moving the bike.

Dunno Roo, I'd have thought spot welded on the outside but looking at the pics they could have been assemble onto the mounting plate, welded on the inside of that plate and then the plate welded to the collector box.

One thing you may have considered but decided against because your not sure how it would look but I had a set of 1300 headers done in CermaKrome a few years ago and they were all in one piece like yours, looked like this at the end.







Not as bright as chrome but no rusting afterwards and extremely durable. Still in perfect nick when the bike got written off, I'd have salvaged the exhaust headers but one pipe got crushed.

Not uncommon to see all the crank holes the same in the cases, seen quite a few with letters all the same and the same with the cranks, seen a few of those as well but both together? not seen that as far as I can recall.

If that frame number is correct why's it got a K0 number beginning with 1 when it should be beginning with a 2 if it's a K1?

To echo K2s comments, ULEZ comments can interest a lot of other members who own other bikes which they may be worried about passing the ULEZ regs, so even though the comments were off track they can be very helpful for others reading the thread. Who for instance knew about a certificate of conformity?

Interesting exchange this one. My cases were stamped CCCCC. The crank webs were marked A1 and the rods D2.

All journals were in perfect unmarked condition. From this I deducted: Mains C1; big ends A2. All rods being weight ‘D’. The engine was untouched, as far as my forensic skills can tell, and the mileage being confirmed as 17k miles.

Some queries: how unusual is it have such repeatability in the cases, mains and big ends ID? Did Honda get better at manufacturing tolerances or just more relaxed about machining and weight tolerances? Motor is a 1977 F2.

Luck of the draw TBH Phil, nice when it happens but it's rare TBH to see it..

Spot on with your deductions.

In that case you'd be correct with 6 greens and 2 browns for the rods. The crank as I'm sure you've worked out are all yellows. Hard to find these days.

I have some if you need them, got more than 10 IIRC.

Just spotted this, get in quick, nearly over.

Good rechrome and better than new. At least it's not bashed about.

One on Ebay in Germany, also a K7/8 one on Ebay in the UK but TBH they don't look identical

Not tested, I read the ULEZ regs and found Euro3 was exempt, then inputted my reg on to website and confirmed it was indeed except. The 08 and before model 1300 was only euro2 and thus failed emission levels. I also got a emission statement from Honda for free to ensure exactly what it was giving out. Certificate was free IIRC but they'll only issue one, if you lose it you're knackered.

Just found a post I did on it on the 1300 forum.

It appears that to get around ULEZ laws you need an engine that produces a Nox value below 0.15, now Honda in their infinite wisdom didn't show this on your V5, they should have but they didn't. So there are a few things you can do, pay the daily £12.50 charge or get the bike tested, place in Romford charges £175 to test the bike and give you a certificate of the results, if your lucky it's below the threshold, if your not you've just lost £175.

BUT

You can ask Honda for a Certificate of Conformity, it's free of charge unless you lose it in which case they charge for a replacement, moral of this story is DON'T lose it. The Certificate officially states the exact specs and includes full emissions date for a specific frame/engine number as tested and provided by Honda.

So ask for this on this website

https://www.honda.co.uk/motorcycles/my-b...rmity.html

If it returns with good news eg less than 0.15 Nox, then scan your Certificate and your V5 and send them to the TFL website and your trusty steed should be exempt when they reply in writing.

The author of this info just got his 2005 900 Hornet made exempt so give it a whirl, if one passes you'd imagine they'll all pass. Saves you buying a new bike if your in London.

Just for further info, the Euro2 Cb1300 had a Nox figure of 0.164 but my euro3 Cb1300 was according to the conformity certificate a NoX figure of only 0.056 which goes to show what a difference it makes. The euro2 model didn't have any CATs in the exhaust, the euro3 has 2 plus lambda sensors etc and a revised ecu setting.

The easiest way to remember to what letter and code to use is this.

The ones on the crankcase are letters, always remember that. Those are the ones stamped into the back of the bottom case usually, like BBABC. Honda would not do a letter and letter combination as there's far too much chance to get it wrong, so if the crankcase is letters then you need numbers off the crank to select the main bearings. If you remember that then it's simple to work out that the only thing left on the crank printing/stamping is the letter, so those must refer to the conrod journal. Again, must be letter/number combination so if crank is letter then rod must be number, that leaves the letter as the weight code.

If you can always remember that then working out what is what becomes so much easier.

It's the letter not the number that's the weight code Ted.
