most 2t scooter motors use about 7gr weights give or take
about a 1/2gr.
however when changing other parts like springs ,or adding a pipe or cylinder
you may add or subtract about 2 grams. that being said its not gospel
just rule of thumb..thats why you have to "tune " the variator..
a.d.d. isn't that just another term for stuff is boring ?
give most people a tv remote and they suddenly develop a.d.d.
