    hello friends well once again I have a problem I need help with. I was riding home and was about at 4k and my bike started cutting out like the battery was loose or a wire was coming loose. anyways got home and the battery was good so I started checking connections nothing loose there either so I start her back up and start revving the motor once again around 4k she starts cutting out and back firing. under 4k she runs fine. could this be the ignition going out or my timing somehow get off from the vibrations? help this is my daily driver. a little back ground info I have 62k miles on her just rebuilt the top end has a new temp sensor New plus and wires new speed sensor a used ecm from Alex if you have dealt with him he is super honest and always helpful also I have air box delete with k&n filter and a buell race pipe... I also timed it after my top end rebuild and has ran like a champ for the last 1500 miles this just started today. thank you all for any help what do ever
