#1 is almost too good for an air cooled bike. As long as you don't have problems with it being too lean it looks great. The angle and distance differences make it hard to really compare, but #2 may be your best bet in an air cooled bike. If it was liquid cooled I would like #1 better, but air cooled needs to run just a hair richer unless you do not have extreme climate conditions. 1 looks like a plug out of a modern closed loop EFI system.
