I don't know where to look next. This bike has the flapper mod, the exhaust valve has been wire open all the way, and the clean mod has been done. The MIL light and FI light stay on continuously. And it poofs black smoke when chop the throttle to 5k-9k. Also when I rev it hard to 8k-9k rpms or under hard acceleration, blows a huge ploom of black smoke. It definatly smells and looks like fuel. This Is driving me nuts!! Please help. Thanks
