I am pretty desperate for a rear cylinder for my veteran Douglas 1917 2 3/4hp "W" model.   I there is anyone who may have one of these that can be re-sleeved or know where I may find one I would be very pleased for the help.  I have a number of engine parts that I can exchange such as matching crankcases, conrods, crankshaft, flywheel etc. Any help appreciated.

Does anyone have the specifications for the oil inlet valve spring for early 2 3/4 engines - Part number 424.   I have tried to order one from the club spares but apparently Jeff Swan is indisposed at the moment.

Hi Team,
Could someone tell me how to fit Ensign tyres to my 1926 ew? Is there a special technique?

Cheers,
Simon

Yep there is: https://www.douglasmotorcycles.net/index.php?topic=6160.0

I use Michelin 3.00-21 heavy duty tubes (not the super duper heavy tubes that come in a shoe box!). My only experience with Ensign was when I bought a pair of 28x2 tyres - the tubes with them were complete rubbish. Rapid deflation should be a concern for all of us using BE tyres, so always use high quality tubes.

Thanks Leon,
We will check that link.
I know about the tubes - from Brian - and have quality one ready to fit with the tyres!
Cheers,
Simon
