If you’re familiar with a whole range of older motorcycles like the Brough Superior or vehicles like the old Morgan 3 wheelers, you’re probably also familiar with the J.A. Prestwich engines that graced these old machines. They were gorgeous pushrod singles and V-twins built during the first half of the twentieth century and used for both road going and racing purposes.
So what happens if you have one of these old engines and it needs to be rebuilt? Cameron Racing Engines is a small company that machines various components for the Ministry of Defense over in England. Having all of these very high precision machine tools sitting around and having a long standing interest in motorcycles, racing and hill climbing got them thinking about doing a little engine work. A little became a lot and they can now provide most anything you need for one of the JAP engines, JAP 8/80 1000cc, JAP KTOR / JTOR 1000cc “dog eared”, JAP LTOW 60′ 1100cc and more.
I love finding businesses like these. Cameron Racing Engines is another of those machine shops that seem to be tucked away all over the UK, turning out some really fine work for old British engines and motorcycles. If you need something for your old JAP, look them up.

UPDATE The very first comment below points to another site building the JAP engines and actually building a new Brough Superior!
Thanks for the pointer, Duncan!
On further reading the new Brough Superior site, the new engines are legally called JAP because the company has purchased the rights to the name and are, what might be termed, “continuations” since some components have been changed, the displacement has been increased, etc. The whole bike and engine are a sort of updated technology version of the Brough Superior and the JAP engine. The engines are even made to mate up to Harley Davidson transmissions and can be supplied with fuel injection. They do manufacture replacement parts for the originals as well which seems to be what Cameron Racing does. The new Brough Superior has the flexibility of putting the JAP name on new designs.
