Also I found one of the larger of the two types myself. Which one is split of the four you sent me...cant see it.

I should have made a note of this at my age with my memory lapses. It was definitely the right side of the bike, I think No.3. Its a small split at the top edge, on the engine side. Thanks Ash.

Had a go at Roy's rubbers tonight ;D Bunged them in a glass dish containing the Reofos 50 for about 5 hours, maintained at 75 deg C in a water bath. Used an old slow cooker to maintain the heat (don't ever accept any invitations down to our place for a casserole! ). Last night "Off down to the pub dear don't turn off anything in the garage" Then she spots where her slow cooker disappeared to .... well I found it in the loft ...unloved for about 15 years !
Because they are relatively rare parts and not mine I don't want to 'overcook' them. Does anyone have a NOS 750K7/F2 one I can compare the hardness with? They are definitely a lot softer now but not sure how far to go . I do have a K7 carb body so I could push them onto that. Is the stub on the F2/K7 head the same as the K0-> K6?
I was going to try to get a bulk amount of the Reofos 50, via my industrial contact and offer it to members here but seems I told you porkies about the toxicity so I have chickened out. Don't want to be responsible for anyone becoming one of Nurse Julies patients !! Magic stuff though.
Link to supplier/safety data sheet .

It states 'Restricted to professional users'.... in the Safety Data Sheet. It's not a known carcinogen or anything like that but still nasty.
BTW There is a guy selling Cyanide copper plating solution in the UK on his website to Joe Public... Scary !! Think he was on Dragon's Den ! http://www.ebay.co.uk/itm/250ml-Copper-Strike-Plating-Silution-/301242031103?pt=UK_BOI_Medical_Lab_Equipment_Lab_Supplies_ET&hash=item46236c9bff

Cheers Pete ... OK so I will try to get a method we can both use to compare the deflection at a given compression .. did you mean NOS?
