1913 2 3/4 HP recommissioning

(1/2) > >>

Black Sheep:
I will shortly be attempting to start an 1913 2 3/4 HP Douglas which has been lying for a number of years. I have had the EIC mag overhauled and will shortly fit it.
My questions: What should the valve clearances be? What should the ignition timing be? How much oil should I put in the crankcase before starting?
It was all running before being laid up and still has its Banbury Run numbers attached.
Gordon.
P.S. Any hints about riding a bike with 2 gears and no clutch. Could be interesting!

Black Sheep:
Well, it (the 1913 Model O) runs. Next thing is the road test. A question. The left handlebar lever controls what appears to be a crankcase decompressor. Is it? If not, what is it and what is it used for. :question:

John W:
Hi,
i'm new to this site, but to answer your question yes the lever is a decompressor.

The cam is within the timing chest, and the lever lifts the valves from within there.

I too have got a pair of Dougies running this last weekend after a number of years in storage.

Can't wait to get out on them now  8)

hope the above helps.
regards,

Black Sheep:
One more question... How is the 2 speed gearbox lubricated? I have a reprint of the Douglas handbook on its way but it hasn't arrived yet.

philpjuk:
Valves should be set to the thickness of a good quality buisness card! I use sae 140 in my gearbox,I have read you must not use lard or windmill oil! to change gear,squeeze the valve lifter and "feel" it into top,changing down is a little more tricky and if you are stopping it is as well stopping in top on the valve lifter,if you really need first then just shut the throttle a little and with a quick pull on the valve lifter pop it into first.Dont let it worry you,get a little practice,Im sure the squaddies in france gave them plenty of hammer with no real problems.Keep your trouser legs out of the chain!phil.
