Have you had it on a calibrated scale before and after?
You don't have as much chrome on yours as he did lol...Literally every single metal part on his bike was chromed. Head, block, cases, the case of the starter... all of it lol
You maybe added a few pounds tops, not that I would ever consider that to be a problem on any street bike by any means. A chromed wheel might add a pound.
Hell, I am pretty sure I add more weight to my bike by eating too much and bringing leftovers home than most of what is in this thread.
