Hi everyone,
I've just bought a 1936 J12 that's going to need a big restoration to get it on the road. Any idea where parts can be found?

WOW. Very nice find. Really a rare bird.
Check with Leon from the Netherlands...from Leon's BSA pages.
(Hoppenbrowser) or something to that effect. I know at one time he specialized in 30's BSA. Maybe he can source a few things for you. Much of what you need will be tough. Hope you have things for patterns, etc.etc.

Good Luck. Show us pictures, please!

Post some pictures. Where in Vancouver are you? I'm in North Van. I would be interested in patrolling by to have a look.

Try these guys, Cornucopia . I have not dealt with them directly, so I can't give you any recommendations one way or the other. I do know that they cater to early machines.

There is a dedicated forum for BSA V-Twins .
It is a Yahoo group and well worth your while joining.
They are a really helpful lot and yes, the afore mentioned Leon is on there

There are about 120 people on the site.
If you want to see some activity join and introduce yourself.
Did you actually go into the archive and look at the quality of the material there ?
The limited posts are a bit af a blessing.
There are a lot of forums with 100's of posts per day all of which are garbage,
However nothing is compulsory if you want to stay with a list with about 4 V twin owners on it and a lot of chater rather than a group with around 70 V twins and few posts then that is you decision.

Hey everyone,
thanks for the replies. Turns out the machine is a bitsa. It's a 1936 J12 engine in a 1932 single frame. Still very cool but for all the purists out there it's not what it seems. Can you all give me feedback as to keeping it or let it go? Possibly part it out so it can become what it could be for many?

Does this help?

http://www.britbike.com/forums/ubbthreads.php?ubb=showflat&Number=169660&an=14#Post169660

The bottom line is:
1- You send your photo to a public album (Photobucket or other);
2- You post the URL of the photo in the album on Britbike.

I would love to do such a project, as its not an original bike there is a lot of freedom to do some nice mods, maybe a bike in 30ies racing style... A friend of mine is doing something similar with a tuned ZB34GS engine in a M23 Empire Star frame from 37.
If it has the requiered documentation to get it on the road with licence plate i would go for the project, but its a project where you need a lot of mechanical skills and ingenuity to finnish, you can not expect to find many parts that fits directely on without modifications for this bike.


best regards

A very rare and desirable engine and the basis for a lovely special. If it were mine, the last thing I would do is "restore" it. The patina is very pleasant to see. Again, if it were mine, I am pretty sure I could rig a simple coil ignition set-up, dispense with a dynamo and circumvent the cons that pachy quite rightly identifies. That said, I have the experience (I am old), the skills and the facilities to make this work.

Hey Everyone,
thank you all for your thoughts, advice and excitement. It was at first a let down to know that it wasn't a true J12 but really it's now in my mind like a pre-war "Triton", if you know what I mean. It would be great to think that there might be some awesome story to how it was built up as we see it now. I feel that the frame will need to be lengthened to accommodate the engine properly. Any of you know what the single down tube frame is from? Leon Hoppenbrouwers says it's a 1932 BSA single frame. I really like the patina too. Here are a few extra parts that came with the machine.

Can't really see much of the clutch, but that looks to be a BSA transmission of the proper era, but the lever positions aren't quite right.

The Y series used a forged backbone frame with the engine hanging off it.
The frame is bacically the same as the sloper frame except that the steering is about 2 deg shallower ( from memory) pushing the front wheel further out.

Now Sloper frames while not being exactly common do come up fairly regularly usually at swap meets on the stalls of the not so young and computer illeterate .
Being a forged spine, it is a fairly easy job for a smithy or boilermaker to alter the steering angle.
Just another option.

In the frame it is in it will be way too high for comfortable riding but that could be over come with some new engine plates.

Ignition can be done with a pair of model aircraft electronic ignitions most of which will run 50 - 100 hours on a couple of ni-cads. These ignitions use solid state electronics to generate the ignition spark thus do not need energy gobbleing coils.

another option.

Making a special out of the engine is a reasonable thing to do and if you rally it there is a better than average chance of finding all the correct parts for it as owners of very old bikes rarly troll through the classifieds looking for ways to off load their hoard but they do go to rallys and are oft very generious to owners loking for the "right" bits

Hey Awesome,

A friend of mine found a fellow in the UK who was making reproduction Y/J/G frame forgings. He is building a JAP special but if you're interested I can maybe put you in touch to find the fellow who makes the frames.

I would be interested Alex! Pre war machines here in Canada/USA are so rare. I can't believe though that this machine has parts from what appears 3 different bikes. I found it on Vancouver Island and a lot of things that get there never leave. I found a Triumph Tina scooter from Victoria a few years ago. I think plenty of british ex pats brought their possessions with them from the UK. The Tina scooter still had UK plates on it.
