I have a 2006 Heritage. There was no spark to the plugs. Was turning over real good. No spark. Good fuel. The service dept. told me that the coil hardly goes bad. It might be the crankshaft sensor. I replaced it and it started. Then a couple of days later it did the same thing, so spark. I was also told to unhook the power commander and hook back up to the stock computer and I did, and still would not start. I change my oil every 5k miles. With Mobile 1 syth. oil. I have 70,000 miles on the bike. Could the stator be a factor?
