Actually I can ask, it would be polite of that person to comply with that request but I suppose I was asking too much.

Nope, I can't think of one good business reason why I would do that Ken.

Thought not. Not into transparency?
I on the other hand have nothing to hide, I'll gladly divulge info, if they don't want to buy then it's up to them. Maybe we should let the members decide who to buy from?

I am mega chill, seriously. I can however only speak for myself.
Trigger:
You need to get a life Ken, instead of searching what other people are doing and then maybe you would get your build finished instead of just talking about it. I thought this was the 500 that Honda should of built, if it took them that long to build a bike they, would of gone out of business years ago.
Maybe you could tell me what i had for my dinner last night :) :) :)
Oddjob:
LMFAO. For dinner, something bitter by the sound of it.
After doing some calculations I can adjust my proposed prices downwards once more. These are for the exact size required, not close, not yeah, I think that'll do the job, made in Nitrile specially for me or Viton when it's required. Which neither of these 2 sets are.
8 tappet cover orings £4 inc P&P. If you can get a lower price than that I can guarantee they are not the exact size that Honda said was required. If you want a close fit I can do those as well, a LOT cheaper. I'll do sets of 12 as well if you want to replace the inlet manifold ones at the same time for an extra £2.
Oil pump kit, all 5 rings, £7 inc P&P.
Crankcase plug Orings, all 4 £5 inc P&P.
I'll also be expanding my range, I'll be doing carb kits for the 500/550 in Viton, all exact sizes, all rings specially manufactured by the UKs leading oring supplier, not 100% sure on the price yet but significantly cheaper than any competition at present Ebay prices.
I may expand into the 400 and 750 markets if these sell well.
I also plan to see if I can sell every oring used on the 500/550, a one stop shop for orings, may even expand into oil seals as well. As soon as these are manufactured for me (and there is a lead time stated by the manufacturer) I'll let members know

Fuelled by this 'debate' I decided to see what original Honda Genuine 'O' rings I had for my 500K0 as I was under the impression that quite a few, particularly for the external fitting of the oil pump) were never included in the gasket sets.
Well I just dug out a NOS bottom end set recently and checked all of the sizes and , to my knowledge, EVERY bottom end 'O' ring listed in the K0/K1 combined Parts Book is included apart from the internal one inside the the Mitsuba starter motor. Before anyone tells me I can't use ancient O rings, I had the hardness and surfaces (in case of ozone damage) on a couple of them checked by my mate at Hull Uni and they measured/inspected just fine so I am deffo going to use them this week on my own engine.
Only query is that there is one extra I can't identify unless I am missing something in the Parts Book. It's the one in the top right with ? ? near it . Measured around 25mm (ID) x 1.65 but very hard to measure exactly. Anyone got an idea where it fits in the bottom end please? Perhaps it's internal on the oil pump?

The one inside the rotor cover isn't listed Ash so isn't included in that set, same set as I have BTW. The 4 x 19.8 x 2.4 rings are the 3 for the gallery plugs fitted to the lower crankcase and the last one is the pressure relief valve on the oil pump. So long as the orings are sealed inside the pack I don't see any problem using them myself. They don't go hard until you start to use them in my experience.
As for the mystery ring, how about countershaft behind the bearing, listed as 24.5 and I remember it's very thin.
So lets see if I can place them all.
Start at the top.
The 4 x 19.8mm rings we've done.
14 x 2.5mm are for the oil pump
11.5 x 2mm took me a while to figure out but it's the shift drum stopper bolt that fits in the top crankcase.
13 x 2.5 is the plug in the left side of the main oil gallery, inside the generator cover.
25 x 1.65mm is I think the countershaft ring.
23 x 2mm is dipstick
15 x 2.5mm is oil filter bolt
89 x 4.5 is oil filter cover
47 x 3.2mm is the oil pump
24.4 x 3.1mm is the starter motor
I know the size of the internal starter motor one as well Ash, got a few in fact.
