Where could I find performance upgrade parts for the 4-stroke Yamaha Vino Classic? - yamaha vino for sale

There are all kinds of performance improvements for the 2-stroke Vino, but I can not find something useful models for the new 4-stroke. I want a little more power and speed then is what is in stock, especially for riding in crowded streets a little more, without affecting traffic.
