i put on the ladder bars late last year and tried them 1 time.went from 9.29 to 9.22 and 1.34 60 foot to 1.28 60 foot. i could raise the front ladder bar to do BG wheelies but im loking for best ET and mph. i like the hook and book technique. ill leave the big show stopping wheelstands to BGR and my new employee CHAZ!
