 cyclobutch,
You probably meant  J.A.P speedway engines ?
Built by the company founded by  John Alfred Prestwitch (London)

Serious  competition with "vintage" engines now means that most competitors use replica motors from companies like these

 *smile* You did not. It's a very old "Censored Words" setting on the forum, some thought that j a p was not respectful, so was set to change j a p into japanese. Spaces added to avoid the censor :O)
Sorry for the confusion.

I'm not sure of how the math is done, or what crank may have been used, but you could stroke and bore the engine to get pretty big CI numbers.
