I got really nice CB72 cam & rockers from him but an overpriced rear rim, that I ended up not using .. wonder what he means by running marks?
MrDavo:
If it's nagging doubt you want, try this:
A very familiar shaped mark in the wheel at 10 O'clock. Absolutely no sign of Bubba's hammer here, I initially dismissed it as a water mark or something. However now its in the good light on my desk, on closer examination..
(a) Its almost exactly the same shape as the missing piece
(b) It doesn't show up too clearly in the photo, but if you look realy close there is a tiny knick at the right hand edge of the mark, at the very corner edge of the wheel. I remember spending hours polishing conrods because cracks start from knicks.
:-\ :-\ :-\ :'(
The thought of that piece suddenly making a bid for freedom and wandering around the engine would definitely spoil my riding enjoyment, more so than just a pice of damping ring.
Thanks for that German eBay link, I found that one last night but couldn't see it today. A shame they don't say what year it is, I'll check to see if he has other 450 bits, that might give me a clue. they change mid K5. I think the running marks refer to the bearing journals, which do look pretty scored Would this do any harm in my cam holders, or just hold more oil? I would imagine if the alloy parts were also as worn you would have a problem, mine are OK. However it is this side of the pond, and therefore not subject to taxes etc. (Don't get me started on #@%$, please, or we'll soon be on page 15!) It is the best on eBay at the moment outside the US probably, DK have a couple of mingers.
I did email to ask what year or model its from, however picture #3 shows a keyway. Mine has a hole there, no keyway, I don't understand what the keyway could be for (oil retention?), as this bit runs in the bearing behind the points oil seal. Maybe they changed the way they built it up at the factory. The advance retard runs off that knockpin, same as mine.
I notice on DS's site that the cam that ends in 003 is shown as superceded by the later K5 one 013. That implies that they are compatible yes? A post on the twins site said the profile and tacho drive changed, but the tacho drive spindle is a seperate piece, driven by the slot, so this might be BS.

Wonder what the exhaust cam is like on this set Dave...worth a call

MrDavo:
I made them an offer on just the exhaust cam, they are going to get back to me (the inlet cam is rough, as is the other exhaust cam they have). Its a lot to buy both considereing the inlet cam is dog rough, I'd struggle to sell it on (which makes it unlikely they will want to split them, but we'll see).
Another possibility is this one, about £46 delivered, no hidden extras. Rust wants cleaning up around the points seal, but servicable bearings and lobes as far as I can see:

The downside is a couple of weeks to get here from Georgia USA, but the stator cover came way before eBay's estimate.
What do you think? Slow to get here but less marking on the bearings than the German ones, the DK ones are a bit of an unknown quantity, but the cheapest if they'll split.
EDIT: DK won't split, so its an expensive cam that you can't see too well, with a free paperweight. Georgia then I think.
