Have 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.

A comment was made about the somewhat strange and noisy Siamese exhaust arrangement. Found a pic of T Thompson racing a bike with a similar system in the early 20's. The date a bit unclear but said to be the same design as ridden by Bailey at Brooklands in 1920.

Thanks for all the comments. Yes the TT web site is not easy to use but I did eventually manage to do a search on the surname Lloyd and from 1907 to now there were only 5 riders with this surname and the ealiest was in the 1950's. See attached screenshot. There is no record of anyone with the surname Lloyd back in the 1920's. Thanks again for all your help.

General Douglas Discussion / Model Z steering damper
Last post by saluki42 - 30 Nov 2024 at 11:03
Hi, I'm trying to find some details of my Model Zs steering damper parts. The attached are the parts that cam with the bike, the strange lump on the end is I believe the remains of the adjusting knob which was melted in the fire 40+ years ago.
Looking at a post from 29th September 2009 it appears to be the same arrangement as that used on the 36 Aero as posted by Doug. what I am missing, apart from the adjusting knob, are the friction disks.  Any information on the number of disks and any special features I should be aware of such as locating devices etc would be very helpful.

Thanks
Chris

Hi Roy and EW-Ron

Quote from: EW-Ron on 29 Nov 2024 at 06:41 Getting some inkling of the exact year of his bike would be helpful.


Cannot say when the picture of Lloyd was taken but can have a bit of a stab at the year that the bike may be from.

The dummy belt rim front brake looks like these from 1920 (27 8 1920 La Sarthe) on Kickhams, Alexander and Isodi's Douglii.

https://gallica.bnf.fr/ark:/12148/btv1b53051634d

Carburettor setup on Lloyd's bike appears very similar to this;

https://gallica.bnf.fr/ark:/12148/btv1b9034137r

I assume all the Gallica pictures are all "works" bikes??

(Links to these pictures were previously posted in the Les Bailey thread at

https://www.douglasmotorcycles.net/index.php?msg=26613

)

So it appears to me that Lloyd's bike is very similar, but not identical to the works Douglii used in 1920 at La Sarthe (Le Mans)?

Cheers

All the competitors in the IoM races are listed online these days.
I haven't quite fully mastered how you search, but Tommy Lloyd doesn't seem to be listed (??)
There are a few Tommy's and a few Lloyd's ...

Some of the listed Junior races are  (assuming a 350cc bike)
https://www.iomttraces.com/racing/results/?event=mnh-event-293
https://www.iomttraces.com/racing/results/?event=mnh-event-288

Even changing the required year of the race seems to elude me at present
I found these accidentally (!!)

Getting some inkling of the exact year of his bike would be helpful.
That siamesed / muffled ? exhaust looks interesting - and unlike anything I have sighted ?
The RA disk brake (?) might peg it at 1923 ??

Again, thanks for the speedy reply Andrew, this sounds positive, however I am actually a messenger for Chris Bates who is looking for the kick start but does not have web access, I will pass on the good news to Chris in the morning, or if you wish, you can speak to him direct on this landline No ......01947 810301....... this is a Whitby, North Yorks number.

Many Many Thanks

Indeed it is. The larger diameter is 18.0 mm, the smaller is 15.3 mm. Centre-to-Centre, the overall length of the kickstart is about 168 mm.

Thanks for your reply Andrew, can you confirm if the "spigot" is tapered and if possible the diameters at each end of the taper. Many Thanks
