Meeting of English motorcycles

[JARO]

Nice photos!! I will be in Jelenia Gora Tomorrow as after the IJR I have 2 weeks holiday left-We were there about 30 years ago on my vincent and sidecar!

Hi atanjennings,
If you are in Poland I invite you to my place.I live in north of Poland .This weekend I will home.
I can show you Gdansk , for example.
16.06. is day off here and I will go to Prague for 4 days.

It's interesting that both valves are operated by only one cam and the valve timing and the opening/closing characteristics (speed, lift) of each is obtained by having different profiles on each of the individual cam followers.

Yes , you are right with cam shaft.
This is shape of piston , look on this part list.

Can you tell me how to name in English cylinder together with cylinder head like on the photo.
I don't know how translate but here people say blank ( maybe this translate makes sense)

Thanks. It must be a heavy piston but I suppose it's a slow revving engine.

I don't know a term for that but I'd call it a 'one piece' or 'combined' cylinder and head. Maybe better informed vintage owners have another term for it.
I've had a look on the Web (vintage forums and Wikipedia) and reference is made to a 'monobloc' arrangement.

It’s also known as a blind barrel.

It’s also known as a blind barrel.

Thanks, here people say similar but difficult translate because this world has double meaning
blank cartridge or blank man / or blind cartridge or blind man never mind.
Polish word should be similar to English because the source of nomenclature and production is England.

The piston is made of cast iron.This is slow revving engine probably
If you are interested you can find something here.Thanks.

If you are interested you can find something here.

I really enjoy reading these old manuals which are written in the flowery language of the 1920's reflecting the glamour and bravado of being a motorcyclist in that era.
I can imagine the author as a pipe-smoking sales chap with slicked back hair, in business suit with waistcoat and and wing collar interpreting the technicalities fed to him by the engineers.
