I have a 97 tl1000s and I have a similar problem. When I am on the gas hard after it is up to temp it acts like the ignition cuts on or off. The thing is its not the limiter not even close to it. Half to full throttle every time when hot. Its driving me crazy. I have checked every sensor they all seem to have the right resistence and the plugs will look perfect when checked. I have changed all o-rings and gaskets on the hole intake system and I have nothing left to check. I have also done this with my exhaust no leaks. I don´t know what to do next. I even had it at a Suzuki dealer and they had it 3 weeks and couldn;t figure it out. If you have found the cause of your´s or anyone has had this problem please give me some insight as to what it is. I have even changed the ecm, aps, wiring harness, vacuum damper, all o-rings, seals, cushions on the injectors,coils, plug wires, plugs, yosh slip-ons, filter, vacuum lines, and don´t know what to do next. I´m tired of wasting my hard earned money on not fixing the problem!!!
