lean pop and missing at steady throttle position
I have an 04 Kingpin that does exactly the same thing DAVEL describes. I bought the bike from a dealer in May this year. I was experiencing lots of sputtering and back fires when letting off the throttle and misses when running at a steady RPM while holding the throttle steady. It would accelerate really strong without any issues. I have taken it to the dealer several times, they tell me the missing feels like an air bubble and they found the fuel injector o rings were cracked, they replaced them and I had them install the S&S air breather, because they said that helps the situation. It doesn't lean pop as much, but still get the occasional miss (air bubble?) while running at a steady rpm. Maybe I am picky, but this drives me crazy. Is this a Victory or v-twin phenomenon? If I ride the bike hard, which I don't normally do, it gets much worse, maybe I am loading up the cylinders? BTW, the dealer told me that he has a 2009 Kingpin that lean pops very badly, due to the lean emmissions settings required by law and the fix is to install a power commander. Ideas?
