I was storing a Harley Davidson for a relative and went out to start it up for a few minutes to charge the battery. There was a set screw on the throttle, so I set up a fast idle. While it was running/charging, I got distracted and went about doing something else. When I returned to the garage, oil was spilling out of the reserve oil tank under the seat.
I shut off the motor. I found the plastic plug that closed the fill hole for the oil tank had melted from the hot oil and flew/fell out. The oil smelt burnt. I changed the oil and hoped for the best.
Later, a family friend was driving the bike down the highway and the motor blew. I wonder if I had anything to do with that?
