mods include Fmf gold series fatty's, K&N , tors delete, Ive been told its jetted but have not torn into the carbs yet. I have pulled the plugs and the bike is running a little rich....makes me think the carbs are jetted to big. Also one side of the throttle cable is broken down near the carb where you can make adjustments to the tension. This could also be adding to the problem because that carb is thrown out of sync just a little.
