My first agility were a 2008 model, and that had a restricted CDI. Then my new scooter is a may 2010 model, and the CDI is slightly diffrent, as there is a bigger piece of plastic in the connection in the old one, than in the new one, so the new can be installed in the old bike, but the old CDI cant fully be installed in the new, as it wont "click".
Although the new could be started with the old CDI, but standing stationary, it didnt seem like there were any diffrence in the revs.
I'll try going for a longer ride soon with both CDI's to check if theres a diffrence
