good pic, I haven't seen that one, and it looks like the same day as the static shot above, but the generator is not the odd thing, its the starter, the one in the static picture shows it as a Bosch, and all 18,720 (ish) 650/750 bikes had Nippon Denso. The earliest Evil chassis number that I have noted is 1053, that bike cannot be a Bosch starter bike, its too late being the 53rd built!
