Got an oldie here (not a Goldie). Just picked up a project bike, powered with of all things, a 1932 J.A.P. 600cc, single cylinder flat head. What up with that!? Of course I don't know anything about that particular engine- what machines used that engine, what are the specs, etc. etc.? Anyone got the goods on this one? Engine is rebuilt and good for something or some one and I need to decide weather or not to keep it in the Ariel frame or part it out. Thanks
Iron Ariel, I would love to see some pictures of your bike. I myself have a 600cc JAP engine (for a very long term project). Mine is a '33 with a "Sports" designation. The head and cylinder are one big piece. Versions of this engine were used in everything from pumps to rototillers to Cotton motorcycles, just to name a few. Here is later model with the separate head and cylinder: J.
Piles and piles and piles...

I used to have an AJW sidecar outfit powered by a JAP 600cc side valve.You say it is a project bike.Do you have a fuel tank if it is an AJW it will have a raised V on the rear end of the tank designed to direct rainwater away from the riders vitals.It was a feature on AJWs for years.(we are talking 30"s here).I seem to recall part of the frame was a casting. Good engines. Good luck with the project.
