Like most things, it depends. First, how long are you holding the bike? If you plan to sell in five years or less there is no vintage, all original premium. Also what type of bike is it? If a dirt bike or a true adventure bike, upgrades and mods are often pluses...especially in cases where a bike has known deficiencies. For example, a 4 year old adventure bike with upgraded suspension will fetch more $. As for the CB, who knows; however, I would always hang onto the stock components.
