Hi, I am pretty new to the fuel injection stuff and have a question about one cylinder seeming to be running a lot leaner than others. It is a gen2 dragbike, carpenter head and cams, stock pistons, factory fuel injection and ecm. Bike is dragrace only and doesnt get driven other than the racetrack. I have decided to put an 84mm piston kit in and when I pulled the cylinder head it looks like one cylinder is running pretty lean or else the other three are just running to rich. Bike ran perfectly and have put a couple hundred runs on the combination it had. There are no air leaks at intake boots or other signs of problems. Anyone have an idea if this is normal or something I should address and where to start?
