new owner fora 2012 python . when slowing down it bucks terribly. I have checked wires, spark plugs, use high test gas all of the time. I own a 2006 big dog chopper with the same s and s motor and it does not do this at all. I have no manual for this bike, bought it at an auction( said it only had 2500 miles on it). I am beginning to doubt this strongly. Looking for another owner to talk to and get some help.
