At rugby practice yesterday - field manager turned off the lights on us as we were gathering up our stuff.(five minutes early) I ran over to my bike and pulled it in next to where we were gathered, trying to sort out gear, change out of cleats, sign in the newbies, etc... and shut it down and turned the lights on. No sweat. I'm in the middle of getting my cleats off and I hear my bike start cranking... I look up, and one of the guys (winger, go figure) is sitting on my bike cranking the hell out of it, and wondering why it won't start. I stand up and helpfully point out the kill switch is OFF. Dude, get off the bike. Everyone leaves, I go to start up for my ride home - yup, battery light illuminates. Blown fuse. Thanks, bro. :huh I wouldn't have minded if he'd asked. He's a good friend, just kind of one of those spacy goofball types. I humiliated him on our club's page for retaliation. (Yeah, you totally blew a 25 amp fuse, you're gonna have to cover that... 'sorry, so sorry, I'll totally make it up to you' I finally let him know that he owes me less than a buck. All in good fun. ) We've all messed with buddy's bikes - but what stuff have your non-riding friends screwed up just by not knowing much about bikes?
