Clearly electric start, interesting gearbox outer cover, I was looking for a hydraulic clutch for a moment but cant find anything...? That is certainly some inlet on the rear cylinder, Mikuni carb? Exhaust appears to be 2 - 1 - 2 system to something like a couple of supatraps? Those girder top and bottom links do look a bit slimmed down for me too; cant be accused of slimming down the eccentric for the rear chain though!
Looks very nice, impressive bike.
