Hi Bob,
Great to hear from another Dragonfly owner, mine is running too, but I would like to check the tappets over, they seem to be rattling a bit, or maybe this is normal?
I managed to take it to the final bike night at the Triumph factory last week, she got a lot of interest.
We could probably meet up in the new year, if that is ok with you.

I've got some somewhere Haven't seen them for a while and will dig them out tomorrow. They fitted P&H lamps and Lucas. I seem to remember some were thread fit others tapered and some doubles and singles. I assume single for the rear. I'll post pics over weekend. I'd be happy to post anything  that will do.

That would be FANTASITC! Thank you!

Douglas Motorcycles - General Discussion / Mark 4 forks + valve guides
« Last post by Laurie on 30 Sep 2022 at 13:52  »
Recent purchase of first Douglas. Front forks inoperable. One has reasonable resistance. The other none until a sash cramp vigorously applied. The travel was the same so assumed different springs. The bottom cap on the soft side was difficult to get moving and that on the strong side worse. Some form of loctite used to compensate for v poor threads. All the strip down evidence on the soft side suggests never been apart. Tapered spring (I read somewhere = more comfortable ride than parallel spring if riding solo). Surprised when second fork's spring also tapered at same angle BUT one weighed 1.134kgs against 1.000kgs whist the parallel weighs 1.300kgs. So were there two tapers i.e. medium and soft?
I'm lucky enough to have a toolpost grinder on my lathe so can grind to create a matching pair of softs but won't do so yet in case it's the soft spring is a maverick.
I can't source valve guides. The old ones look to be austentic? cast iron which is a pig to work with and tolerancies are so crucial I'd prefer to purchase if possible either iron or phosphor bronze. They're  not available via the club at present.

Hi Jixxer.  I too have a 57 Dragonfly and am in Leicestershire - not had a chance to take it out much at all this year with one thing and another but fingers crossed I'll get a lot more use out of it soon!
Best,
Bob

Hello all, Iím a new member to the Douglas family after purchasing a 1957 Dragonfly last month, my name is Stuart, and I live in Leicestershire UK.
The reason for this post is to find out what tools other owner use for the rocker cover nuts.
Is there a specific tool available to buy?
Do you eventually have to mackle  up your own tool?
Or is there anther manufacturer ei bmw that make a tool that will do the job?

I look forward to your replies, thank you in advance.

Stuart.

Douglas Motorcycles - General Discussion / Re: Douglas V 4

Absolutely true, but a camshaft running in the open was an anachronism in 1907, on either bike or car.

A bit of this primitive design was also evident on the first Douglas twins at the same show: the rockers that changed the direction of the exhaust lift from the horizontal tappet to the vertical valve ran in the open, as did the final magneto drive gear. The better designs of the period - the Belgian FNs for example - had all this type of stuff well sorted by 1907.

Still, both the twin and the four were nice little engines for 1907, when multi-cylinder engines were uncommon.
