Hi Andy,

Douglas used five or more different a/r levers in the period 1922-1925. Do you have a particular one in mind? If you have the original throttle/air lever on the right bar, post a photo and we can guess the appropriate style of a/r lever for the left.

Cheers

Leon

Hi Andy,

Yes that's the "standard" AMAC double lever (T30 HD) that you'd find on most 2 3/4s. The Douglas version would usually have a single bolt through the handlebar; you can use the clamp as is, or modify the lever to bolt through the hole in your handlebar if it's there.

In an earlier thread we discussed levers on the veteran and WD bikes https://www.douglasmotorcycles.net/index.php?topic=5151.0 with the conclusion that, although AMAC made a magneto lever to match the T30 HD double lever, Douglas rarely/never used it. Instead they usually used a lever made by Bowden Wire Ltd. The 1923 version of the No. 403 would be fine on the 2 3/4. Attached is a photo of the pair I have gathered for my RA (clamp-on, rather than single bolt, mount), and a 1923 advert showing the mechanism.

The bad news is that I've fossicked in the shed and can't come up with an inward-opening Bowden lever for the left bar. Sorry.

There are other similar levers that would look fine.

Cheers

Leon

Hi Daren,

OK I looked. I'm not a facebook person myself, mostly because of the long-line-of-waffle-disappearing-down-the-page-to-infinity format and the absence of expertise on display. I wonder if facebook is the "source of the future" for information about old bikes? On a forum like this one, information is shared and reasonably ordered, and usually there is a long enough attention span for a question to be answered or a motorcycle to be identified. I have rarely seen this on facebook: a few likes, perhaps a couple of comments for a few hours after a post, then the show just rolls off the bottom of the page...

But some of the scanned literature is nice.

Cheers

Leon
