Ok, out of nowhere my bike started running very poorly and stalling out while riding. When you grab a whole hand full of throttle its like something is holding it back, engine doesn't sound right either. Most of the stalling is a deacceleration. I thought the culprit might be the Sumax wires I installed, as they did not check out so hot on my ohm meter so I went back to factory plug wires, and got new plugs, no change.is it possibly the coil? How do you test it? I then started to think it was the Power Commander so I contacted DynoJet and they told me to run a zero map and see if it improved, no luck. I bypassed the Power Commander for a quick pull down my street, no luck still running poor. My next step is to put all stock items back on and start from there. I am only running V&H Big Radius Pipes and a Screamin Eagle filter kit. Using a FuelMoto custom Map on the Power Commander. This setup has been fine all last summer, and all of a sudden hit with this problem. I also think the bike is running much hotter because I can really feel the heat coming from the engine. If anyone can steer me in the right direction it would be a big help.
