Hi,
Do you have the original CDI, my freind have a brand new AGILITY CITY 50 and with the original CDI top speed is 50 km\h.
When we remove the 2 purple wires, he hit 60km\h.
It sure when i install his 72cc kit, he need to buy a CDI with no restriction!
My Kymco People S50 2007, have the same motor of the Agility City 50 2013 and i have a 72cc kit, original cdi unrestricted and my main jet is a #90!
Good luck!
