Help !!! Had the tank off this weekend and hoisted the bike up by the top tube whilst aligning engine etc. Also fitted free flowing exhausts at the same time. The engine management light comes on whilst the system pressurises, goes off briefly then comes on and stays on even before starting. Light stays on permenantly and the bike is flat out at 95mph and holding back. Have i disturbed something and if so what? How can i read the fault? Also can the ecu be programmed for free flowing pipes and filter? Be gentle with me its my first time!!
