2025-06-04, 05:57:00Does 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.

2024-06-11, 21:02:05Have you tried the new Drafts feature yet? I just lost a long message today and learned my lesson. It is a good idea to save a draft of any long post you are writing. You can then just keep writing and keep saving a draft, knowing you have a backup if there is a glitch. The draft is automatically deleted when you post the message.

Last post by graham-xrfx - 25 Jun 2025 at 15:06Quote from: DSIM on 20 Jun 2025 at 10:59 HiHi there
I have a pair of domed NOS T35 pistons +60 complete with all rings fitted and gapped. They are unused. Just getting rings for your reworked pistons will stretch your budget, reboring to +60 would be an easy option. A reasonable offer plus postage and they are yours.
Best regards
Thanks much for the offer. As it happens, the machining has been done, and the rings had already been ordered.
Your pistons might yet see a role, depending on what we find inside the FT35 that has been in a Scottish basement for 80+ years, and also, I have to ask the colleagues if they want to do anything with it. That would not be a trivial project!
I have not yet figured out how to send PM message on this forum

Video of the bikes running from a few weeks ago
It's time for these 1951 Douglas Plus to find a new home (ideally together – but happy to separate).
Both are set up as clubman racers, previously by a family member, with alloy engines, Lucas competition mag, alloy wheel rims, oil breather catch bottle, Smiths Chronometric Rev Counter, Smiths Chronometric Speedo (80 only). The 80 has additional rear suspension dampers and the 90 has NJB Racing Shocks, period modifications from when the family member raced Douglas in the 1950's.
I have V5C to hand and in my name for the 80, for 90 I have a "buff logbook" from the 1970's (Green VE60 document)
Items not shown, but included.
80 - Toolboxes, Centre stand, Rear number plate
90 – Toolboxes, Torsion bars and linkages
Collection ONLY - Located in West Berkshire. If you are interested please PM me for more details.

Douglas Motorcycles and Parts Wanted - Private / Re: SW5 flywheel clutch
Last post by Doug - 22 Jun 2025 at 19:31I would recommend searching for a later 3-pin type clutch from a F/31-G/31 or '32 or the OW/OW1 models of 1934-35. Besides having three drive pins for the pressure plate verses two, you can separate the clutch disk from the backing plate. On the SW5 clutch (2-pin) type you have to un-rivet the sprocket to separate, as the hole in the backing plate is too small to allow it to pass through.
I do have drawings for the later 3-pin type if you decide to go the route of manufacturing a new flywheel clutch. I also have an example of the 2-pin type for my SW5, but it has not been drawn up.

General Douglas Discussion / Re: AMAL carburetors question
Last post by graham-xrfx - 18 Jun 2025 at 11:47Hi Ron.
Yes - the firm that supplies pistons to the UK, including Douglas types, is JP Pistons in Adlaide. They even have the patterns and drawings of the (1934?) original. It would be a one-off order. AU$600 (each!) before UK shipping, VAT, Imports taxes etc. I don't think they wanted to do it. It was a non-starter for us.
There are firm in UK that can rework camshafts. I have not explored them. The main need is to fix the one we have.
Going for a cam that would work, and two carbs would give an immediate boost, and that would be interesting and fun. My present ambitions are more prosaic. Just to get it going again, so it can display would be a big deal for me. The interest is about what was it in the little airplane that made it a killer, and the simple fix that makes it safe, but alas, the reputation was ruined, except apparently, to the French. Know also that this one has exhaust pipes without silencers.
I do have another engine, given to me, it having rested in a Scottish basement for 80 years, is in unknown condition. I haven't even looked in it yet. If ever there is to be an audacious modification, then that one would be the candidate.
Today - we cut on piston #2, with fingers crossed!
