Mods ; Firstly I recommend starting with the looks because when you start tuning it hard then you want a strong deck and strong wheels. Also it lightens the goped a little so you want to get used to that, then get a filter and H.P carb , never buy an high performance exhaust without an HP carb always buy at the same time. As the Hp exhaust requires more fuel to burn which the stock carb cannot supply quick enough. I have heard a lot about a cool head but have not purchased one, so I don't know what it is like. It is probably better to send your ped away to get the super mods done properly. You will find a few companies on my links page. Try LMSpeds for help, the guy is friendly and helpful.
