Back to topic at hand. Fixed the problem with Hanso's help. I have one of those dyno jet plugs installed on o2 sensor wire. Tune had sensor unchecked. Went back in this morning and changed all that. With the o2 sensor box checked backfire is gone. Bike is noticeable faster than before. Much faster. Happy camper now were are all those big bad Harley's ready for lunch.:D:D:D:D:D:D:D:D:D:D:D:D Thanks for the tune Hanso.:thumbsup::thumbsup::thumbsup::thumbsup::thumbsup::thumbsup::thumbsup::thumbsup:
