I need some help troubleshooting my roadstar. I have a 2006 roadstar 1700 with 5600 miles. I rode it last week, parked it downtown for 2 hours and when i started it back up, it is now only running on 1 cylinder. So far I have checked plugs, rear cylinder coil, and done a leak down test. At this time i am thinking it is the ignition module. Has anyone ever had this problem? Any help would be much appreciated! Thank you!
