Cylinder head CB750

[Trigger]

.... so the heads are something K2 or later?

Can you identify the cylinder?

All the heads are from late 750. Not sure what they used in Germany but, the UK K2 was fitted with the early head and differ to the USA unit.

Barrels look K0 to me .. What are the bores like? Mileage?

Thank you again for that info!

The bores look very nice. What you see inside is grease to protect from rust.

No idea about the mileage.
All that stuff (and a lot more, mostly sold via eBay all over the world in the meantime  -  I bet some of you got parts from me) came from the PO when I bought the KO.
Unfortunately, he died at the age of 80 (its a one owner bike from new) so I couldn't speak to him. Bought it from the inheritors.

Maybe this is the original cylinder of the bike. The bike itself has more than 240 tkm.

I will keep that as a spare part.

To be honest, I assumed that No.3 could be a KO- candidate.
