Just acquired the scoot, no able to rate it yet. But I´d like to know how different it is from her larger sisters, since I don´t have an owners manual for the 50 but have seen a Pdf file on the big ones. If anyone knows, what is the correct plug gap? Replacement types? Any tips on potential problems with normal use? Have owned Vespa 200s, Lambretta 125, Aprilia 250. Comfortable with 2-cycle.
