Those methanol breathing bitches were and are lethal, one of my younger brothers has only minimal movement in his right arm after crashing one just teasting & tuning in the paddock, that was 20 years ago and it smashed his shoulder and arm into a pulp in a millisceond of stuck throttle and a highside into a camphor laurel on the way.
Cowboy Bob Cowley just rebought his 1970s championship bike back and is restoring it, I remember him and Doohan tuning that thing and the solid 6′ flames on the overrun back when we were teenagers.
It’s probably my favourite form of bike racing to actually participate in, unfortunately the venues are limited these days.
