Permission to kick myself! I hadn't seen the last message, and have now ordered some (and they were somewhat more expensive!). Thanks very much for the offer though.
Were yours on eBay last week, because if so I didn't see them when I bought the ones I've got now?

Yes, ka-ja, that's what mine are like. So if yours were for a CB72, mine must be really early CB500 rings. I think I'll try to source another 2 sets with 3-piece oil rings. I'd feel more comfortable knowing they're the later type and all the same. Thanks for the info.

The top rings are identical in both sets (with a small chamfer on both outer edges). The position of the T mark on the stepped rings is such that the step is on the bottom side when fitted.
Edited to add: A bit of searching has revealed that the stepped second ring is called a Napier ring. I'd never heard of it before.

Thanks very much. That's interesting, as mine came from..........Stoke! And yes, the part number on the box is -014. If anything, I was more bothered about the step in the second ring, as it's something I hadn't seen before.
The received wisdom on t'internet seems to be to bore .0008" to .001" larger than the pistons. At the moment, I can get a .0025" feeler down the side of some of the pistons (it's fairly tight, but even so).

Hi All,
My CB500 was bored 0.5mm oversize many years ago. I haven't been happy with it recently, and have stripped it down. The piston to bore clearance is more than I'd like and compression was well down on 2 cylinders, so I've decided to get it taken out to +0.75. I've sourced a set of NOS pistons and 2 sets of Honda rings from an eBay seller, but had to get the other two sets of rings from DSS.
My concern is that the rings from the eBay seller are different to the DSS rings. The top ring looks the same. The second ring of the eBay set has a step in one side (so the outer part of the ring is thinner). The oil control ring is solid, whereas the DSS rings are 3-piece.
So, my questions are:
Are the eBay rings REALLY old stock (before 3-piece oil rings became the norm)?
and
Would the eBay rings be OK to use?
Any/all advice would be appreciated.

Nothing wrong with HEL, but there are cheaper alternatives. Also note that many suppliers will automatically provide plated mild steel fittings, which will eventually corrode, so make sure you get stainless fittings to go with your stainless hose.

I've tried all kinds of things to improve mine (new cable, cleaned and re-greased the lifter mechanism, CB450 clutch plates) and it's still like an on/off switch. The only way to pull away smoothly is by giving it more revs and slipping the clutch. It's definitely worse than my original 500 (back in 1979) but I can't figure out why.

I've been very pleased with the Bridgestone BT45's on mine, though they may not look original enough, if that's what you're after.

Also looks like it's got a Dresda box-section swinging arm too. Don't see many of them around these days.

I bought the repro items, and needed to do quite a lot of tweaking to get the pipes to sit right and the interconnecting rubber to align properly.

I've had an Electrex unit on mine for 10 years, with no problems.

I thought that the main issue with HIDs is that you only get the correct blend of power and beam pattern with OE installations, because the reflector shape is designed to work with HIDs. Putting HIDs into a reflector designed for conventional bulbs means that you get the brightness, but the beam pattern will probably be wrong. I just put an aftermarket 60/55 halogen unit in my standard headlamp shell, and it works very well.

Winning bid - £3400. I know it's hard to judge, but I thought it would go for a bit more than that.

Looks gorgeous; if only I had enough space.....and money.
I remember going to the Dresda shop back in the day (must have been about '79) and buying one of their box-section swinging arms for my first 500.
