75 Rickman on ebay

Thanks Rich, I don't have any more. It moved on over 20 years ago (the usual story, working every hour, young family, lost storage etc) never got to take it on track as I didn't have "full leathers" but it sounds like you have experienced a good selection of UK tracks.
PS: 73z1 apologies for hijacking your thread with memories of "the past"

Those carbs look like 29 mm Mikuni smoothbores.  (On the RAU)

Wookie,
No apology necessary.
All the comments are interesting.
I never owned or saw a Rickman.

That´s absolute correct, Hardrock!,..but they´ve been on the EGLI ( recognizable by the rectangular casting mark above the floatbowl..i´ve used these carbs on a few old Kakas i´ve had in the past..., For me, always a good choice!)
 

Bye the way about the RAU-Kawasaki:
Later in `85, i´ve mount a, ( at this time very rare), "performance" half-fairing from the KVAS-KOOL-Team, with the oilcooler above the double headlights...i remember, it was a challenge for me, to design and build the fairing mount, complete construction incl. coolermount, headlight mounts, fitted to the frame, easy removeable...racelike ....sold it in ´88 for a new project-plan... ...Always the same old story in my life:  One toy have to go for another dream...That´s the salt in the soup!
