Just thought I would update this thread. Yesterday I put a new Accel Super Coil and 8mm wires hoping that would help. Not! This after replacing the engine temp sensor on the front cylinder a few months back. Maybe my imagination but it seems to start a little quicker. I have Rinehart True Duals and when it starts cold, the right pipe, front cylinder, puffs black smoke then starts spitting and sputtering and finally dies after about 10-15 seconds. If I can keep it running until it warms up, it seems to do better. Before I replaced the engine temp sensor, it was anybody's guess when it would start the spitting and sputtering and finally fuel foul the front plug. So, to date, I have replace the crank position sensor, engine temp sensor, coil, wires and 5 or 9 sets of plugs. I have tried every brand of plug out there including Split Fires and they all have fuel fouled at one time or another. I guess I am going to have to take it to the Harley dealer and hope he don't rip me off too bad. I am afraid to start out on a long trip as it. Course it's still a little too cold to take a distance ride but I want to be ready when it gets warm. So, if anyone has more suggestions, I would love to hear them! Thanks all!
