What really bothers you on a "finished" bike? I hate mismatched grips & mismatched footpegs. Also on minibikes with headlights, the fluting on the lens should be horizontal & vertical, not at angles. On barnfinds one might see anything, but finished ones should be better.
What else?
mix of blackwall & whitewall tires?
different color brake & throttle cables?
