Hi I wonder if anyone may be able to help me I have an 04 s4r monster which I have just fitted a termignoni exhaust and ECU when I started the bike for the first time after fitting it ran for a short time and not very well however when it stopped it will not start again ,wont' even crank over has any one any idea what is the problem ? The pipes and ECU are for an 06 bike but it won't start even with the old ECU back on. Hopefully Brian
