RE: Aftershock questions..
never heard of anyone running without a tuned pipe as these are scavenger engines it needs the back pressure to get the proper fuel mix from the tank (from pressure) and the exhaust ...ditto on the max life shoes and the ht pipe is the cheapest and best upgrade for power...as far as the tranny not shifting it is prob. because of the lack of power from the exhaust missing, all of these do not shift right on the first few tanks anyway ...but it is a great lookin body tho...oh and the way you have the tank mounted , it will not last past your first roll over , which will be soon if not then you ain't driving hard enough
