I guess it was done by Eckert, right?

Am not sure, but wouldn't be surprised if Roland had something to do with it.

Better sorry for failing then for the lack of trying.

Here is a photo of the entire engine in question.. From the Book "Honda" edited by Mick Wollett, first published in 1983 by Temple Press.
Sorry for the bad resolution, but if I scan it...it will be too high a resolution to post.

 That is neat. The cam drive system is different from the later DOHC (and actually looks more reliable). the intermediate gear between the crank and basket is interesting and simple. My father was an engineer for Electric Boat (submarine buliding) for many years and he would tell me about stuff they were doing involving machining, fabrication, welding etc,etc. I would sometimes ask "they can do that stuff???" His reply was always "They can do any friggin thing they want to do" (when it comes to engineering and execution). I believe Honda is the same way. ;) ;D

I found the article about Roland Eckert's RCB engine and bike in an old bike magazine.
Bad point,...written in German, but lots of pics. If anybody is interested in, I  can scan it and email it.
PM me with your email address.
