Well for the time being i have put my old one back and with the new rollers its nice plus its nice to be fast for a scooter again. I will investigate this with putting this Yasuni on some other piaggio family scooter to see and most likely sell it.
To be honest my friend had the same Piaggio scooter with restrictors in it everywhere where they should be from factory and it felt like i never gave its best and i did have the same impression here. Do you know if they are hard to remove?
Everything is full on stock but the scooter's restrictors are taken out. Exhaust was put on yesterday so it was not touched from within inside. My next question is are the restrictors in the Yasuni exhaust ?
I had a stock exhaust on my 2012 Piaggio nrg and i bought a Yasuni z kevlar and after the swap the scooter lost all speed it doesn't pull like it used to and the top speed is gone too. Before the swap it was doing 90 km/h max and it was accelerating quite fast for a full on stock 49 cc scooter...
