I was once at a gas station, and the bike attracted the attention of a few people.
They wanted to hear it start and run.
Unbeknownst to me, the intake manifold rubber had just split on the way into the gas station, and had a big hole in it, but i didn't know it ...yet.
I tried to kickstart the bike
The resulting kickback blew the carb right off the engine, right in front of everybody.
I didn't have a spare rubber hose for the intake with me, so i went into the gas station and got some duct tape, wrapped up the torn hose, and it lasted the 5 miles ntil I got home.
What an embarrassment!
It always happens when people are watching.
