I have an 05 Boulevard C90, Cobra long shot exhaust, Fi2000 digital processor...Have had this system on for a year, with NO problems at all. Bike starts fine, after running on the road for maybe 10-15 minutes, engine becomes very sluggish, pipes crackling, engine backfiring....only to clear up after a few minutes....then the process starts all over again......i have changed out the fuel...dont know where to start..what the heck is going on here?????????
