Speaking of doing stupid shit...have you ever walked around looking for a wrench or socket that was in your hand the whole time? Or, forget to block up the front end of your bike so you can change fork seals and remember that fact in the last quarter turn of the ratchet on the SECOND fork cap being removed? Or, putting the piston of your two-stroke racebike in backwards? Those facing-forward hand-carved skirt windows allow just enough horrible combustion events to take place that you'll think everything is wrong BUT the top-end job you did in the parking lot at 10pm the night before. How about not gluing the grips to the bar, thinking they won't go anywhere 'cause they're soooo tacky, but the first time you enter a turn you end up falling off the inside of the bike?
