Hi I hv brought a yasuni r exhaust for my stock Piaggio zip 50cc and I’m unsure what rollers and jet to put in I know you have to upgrade them by 10% but I’m unsure where to even find them
well hate to say it but why have you wasted your money on a pipe best suited to 70cc sport to mid race ? get your money back or prepare to spend time and more money derestricting and upgrading your Zip to suit your Yasuni R
