Not happy with the thread below concerning engine developments.

The rotary valve stuff was great, Malcolm, and thanks for that, but the Ehrlich material was nothing more or less than history being re-written!

OK, so he did a lot of work on the Rotax twin, but when I see him given credit for split single engine design, among other things, it's going a bit far.

The bloody man never had an ORIGINAL idea in his life.

All the work that needed done on split single motors was done pre World War 2 by Puch in Austria and then DKW in Germany.

Immediately post war, Joe entered an "EMC" 250, which was nothing more or less than a thinly disguised "ladepumpe" DKW.

Of course, we all know about the 125 EMC ridden in the early 60's by, among others, Mike Hailwood, don't we?

Sorry - that was an MZ engine, which the good Doc obtained in exchange for a set of Norton Roadholder forks!

Walter Kaaden designed that one of course - now there WAS a genius!!

Hell of a self-publicist, was Joe, and successful at it to boot.

However, to get the full story, ask one of the boys that rode for him - none of them stayed in the team that long!!

Difficult man to live with, I believe . . . . . . . . . .
