1999 Titan gecko motorcycle 107 inch S&S motor! Would like to find out why it starts cutting out and sometime dies out on me, after warming it up! If I wait 5 minutes or so it will start back up, but sounds like its running on one cylinder. I have already changed the coil. After changing the coil when I start it, it up right away it sounds like its running on one cylinder right away. What else might be the problem here?
