Title: Know it's a Francis Barnett Trials but not year
Post by: Bellhouse on May 17, 2009, 10:59:32 PM

Hi,

We have received a FB trials bike for restoring but do not know the age or cc of the bike  on the engine we can make out  

25 / C       17120


On the frame of the bike it says

AOT13736



Does anyone have any info they could provide us with?  
Thanks from Canada.

Jim and Tia

Looking in Roy Bacon's book 'Villiers singles & twins' gives the following information.
For 1959 the 249cc Model 83 started at engine no.25/C - 16303 & the frame no. started with the letters ACT (you quoted AOT which is not listed as any frame no. prefix), could you have made a mistake - is the frame no. difficult to read?
The Francis - Barnett Model 83 is listed as a trials bike made from 1958 - 59, & was fitted with the AMC 250cc engine.

Yes it is most likely a mistake on our part, I was not sure if it was an
O or a C.  That is great information you've provided us with, now we can move on to locate a parts manual and repair manual.  Thank you very much!

Bruce Main-Smith & Co. have generally been my favourite for photocopy manuals, parts books etc. Here is their link: -

If you can contact John Harding of The Francis Barnett owners club who also advertises in Old Bike Mart re Pistons you might find him a great help.His knowledge of f.b.trials machines is good if not great.Good luck Harry.
