I am putting the S&S intake on my 10 KP, so far all has gone smoothly but this morning I went out to finish up and I found a mystery part laying on the ground near my bike. I have no idea where it came from. It is a rubber grommet, that is a shade bigger in diameter than a quarter. It has a step up from the outer edge then a dime sized hole in the middle. I think maybe it came out of the old airbox, but I am not sure. It isn't a fuel tank mount either, that is the first thing I thought it may be.
