Today i install a 72cc kit Naraky on the AGILITY CITY 50 2013 of my freind.
If i compare with mi Kyco People S 50 2007, they have the same motor but not the carburator and CDI are different.
I try the 72cc with the original CDI(Derestricted) and a jet #90.
First ride, Lot more torque but feel he can accelerate faster (some restriction of the CDI) and at 50 KM\H want die in acceleration (to much gas).
Second ride, Jet #82 Better acceleration and at 65km\h no more acceleration, motor can't get more RPM now i'm sure is the CDI can't give more rpm, so tomorrow my freind is going to buy a new CDI with no restriction and a jet #85 to make some tests.
