I think lost tools are just a part of it; just make sure you don't get any inside the motor

I work at a bike show, and we find tools all the time from when they were building the bikes, and crating them. I forget the brand, but it is something we had never heard of before.

But, this one tops them all; one day we opened up a crate, and found someone's lunch. It was a jap bike, and it looked like some kind of fish; guess he missed lunch that day...

 

Ya I got a socket down there in the Valley somewhere myself.
I wen't nut's for an hour looking for that sucker. It fell down into never never land under the S/C + Manifold.

Like everyones saying, as long as it's on the outside,
no harm done .
