anyone recognise this part ?

Found this on the workshop floor where I've been working on the 500/550 mongrel.  Anyone got any idea what it is / where is came from . The wee hole and groove would indicate that it's connected to a greasing point . Its got the same kind of groove as the swing arm spindle collar. Could be for either the 500 or the 550 ...... or then again maybe its a bit from something else entirely that just rolled of the shadows of the workshop. (that's a 5p piece beside it in the photos). All I know for sure is that its not an internal engine part.

ha .. might have it ... part of clutch lifter mech inside left hand crankcase cover ... goes inside part 5 in attcahed diagram ?

[Ewan 500 K1]

nope its not that after all, just went out to have a look . Part 5 is a single piece unit ... and that mystery bit doesnt go anywhere in there and the clutch lifter is working fine as it is. It doesnt appear to be part of swing arm either. Its not part of the spindle collar as the outside diameter is too big to fit inside the swing arm bush and the inside diameter is too big for the spindle. Its not a swing arm bush either as the inside diamter is too small for the spindle collar to fit through it.

I've seen that part before somewhere but can't remember where. What other bikes have you had in pieces in that garage? I don't think it's a 500 part, might be 550 but doubt it. Could be another bike entirely.

CB125S, CB125J, minimoto dirt bike an thats it
