Let's just say I have a friend with the exact same bike as me. And let's say that it's his first experience with an aircooled motor. Let's, just for s***s and giggles, say that he sits in traffic for a long time and happily idles the bike with nary a breeze in the air. And perhaps maybe, once he's out of the traffic, he putters along the freeway and his bike starts to make loud, ugly sounds. When this friend of mine puts in the clutch in terror, and the motor stops, and he coasts to the side of the road, and I... I mean he walks to get some oil, returns, fills it up, and tries to start the bike, and it actually starts, he is shocked. But he accepts this gift from heaven and pampers it home. Now my friend's bike sounds quite loud, clackity, and just downright ugly. What is the best and worst case scenario for my buddy?
