[QUOTE="oexing, post: 126826, member: 1493"] Norman, you will be right about this piston type found on other engines but as far as I know it was a design from Norton´s Manxes. To be open, would I try to modify a standard Vincent head for this piston - no way ! The heads seem to be quite flexible anyway under high stress so machining them for Manx pistons would call for desaster unless you´d go for awkward welding add-ons to compensate for lost material on top of the combustion chamber. . . . Or have new castings made for them. The very black coat on the shirt will be graphited most likely, common on modern truck and car pistons. Did not like to have graphite in my engines as this is a bit abrasive knowing from my trade as toolmaker and from machining graphite electrodes for spark eroding. So I got special MoS2 bake-on paint for the BMW pistons for having less piston clearances in alu barrels when having car pistons in bikes. See the blueish colour as no graphite in it.
