        If you're running with the stock intake I'd advise putting the carbs back to standard settings with a Marshall and then doing plug chops. A Marshall pipe doesn't change things very much usually and you may be able to tune the carbs in fine with very close to stock settings. Plug chops will be the key though.

        Plus check your fuel tap can deliver enough fuel at high speed.

          you do know dynojet jet # are different than stock jet # ( so a dj 120 would be a stock 127 )
