Thanks for the response. I did a little more research and read that this could occur from even a missed shift etc. I am thinking it is aluminum. I so rarely do an oil change it will be hard to track, but will be paying close attention to the bottom of the oil pan the next time around. The engine runs smooth, and there is never any odd behavior in how the bike runs. I am the original owner and have treated this bike very well since new.
Zoey, I see your join date is pretty close to mine. Are you an old member of SportBikeWorld ? I guess they merged or something a few years ago.
