Why do guys say, "My bike is stock except for etc, etc, etc, etc, etc..." ??? If you have added all those etc., it isn't stock no more!!!
It's shorter than saying : "My whatchama Gixxer is a full on factory prototype except for the stock engine, stock footpegs, stock exhaust, stock frame, stock wheels, stock gearbox, (...), stock transmogrifier, stock flux capacitor, (...) but the mirrors are super pimp high velocity affamahket chinese replacements from ebay since I dropped it in the Walmart parking lot last month when I went to buy some sugar free Haribo gummy bears.
It comes from drag racers.......they like to lie as much as possible as to what has been done to the vehicle
Just like the guy advertising an "all original" GTO, except for the 350 that replaced the original 400, the aftermarket wheels, radio, seats, fenders, quarters, windshield . . . I've concluded they are ads written by suckers for suckers.
