Does anyone have any "speedy-shift" info, pics, blueprints, manufacturer (look up patent?), etc.? It is a contraption that works the clutch and shifter at the same time. I have only seen one on a feature bike in Easyriders back in the 70s (lost those early issues a long time ago). I think it was in the issue that featured Big Armunds Bike, pre #80 and #74.
Additional request for anyone who still has those old issues, I'm looking for a copy of "No Class Chick" by J J Solari.
