I am looking at phbg carbs for my maxi. I have a malossi 60 kit, wondering what the optimal size would be. 19mm phbg's seem to be a pretty common choice, but I wonder if this is too large for my kit.
What changes when the id of the carb changes? Is fuel efficiency compromised when it gets larger? Torque?
are dellorto 17, 18, 19 phbg identical besides the bore?
