TPH NRG 50ccm throttle again

Hi there, I bought myself a Piaggio TPH spontaneously for short distances. The thing is great, however, it goes far faster than it should be. I would have left it that way too only the scooter is for me only for short distances to commute. On the track you can not drive sowiso faster than 50 thanks to professional traffic. Therefore I wanted to know how the things at all are hairdressed or if you can undo that again. According to seller, the exhaust is not m very original but I think that was changed even more. I think that I can optimize the consumption and that I don’t get any problems when I am stopped by the police. That’s my first scooter therefore I have to get more familiar with the technology first. Thank you in advance
