I have a 2000 VStar 1100 Custom with Vance and Hines pipes. After riding the bike for five-ten minutes, it is like someone flips a switch. It will start misfiring BADLY. I have to get off the gas completely and then SLOWLY roll it on. I can only give the bike a max of 1/8 throttle before it cuts out/misfires and goes nowhere.
Any help would be extremely appreciated!
