hi, i have a aerox -03 and i have a leovince zx on with yellow clutch springs, and original weights (i tryed putting on the ones that came with the leovince, 4.6gram, but it accelarated SO bad, like 15 seconds to get to 20 km/h , so now im back with original (5.5g) i think.
What Weights should i have to get rid of the "ketchup effekt" so it accelerates more smoothly and not jumps.

Heavier(how heavy), a but lighter ?!....

and btw, if i buy a polini speedcontrol or a new variator in general, will this fix the problem and get me some more topspeed ?!

ZX comes with 3.5g (15x12) rollers on Minarelli

it says on the little plastic bag the rollers come with "15 * 12, 4.6g"

so...
