i have an yamaha aerox which had a 70 kit on it but it blew up and its completely f**ked.i now have a 50 head on it but its not running at all right and was wondering if any1 had any ideas on how to set it up so i can adjust it if need be. at the moment its got a 99 jet,k&N filter, yazuni c16, and 3 gr rollers and an adjustable clutch with the soft springs and a polini contra spring. im happy with any advice as i have only set the bike up as a 70 not a 50
