Sabre66, good to know I'm not the only paranoid one...
Do you hear a "suction sound" periodically, too. Guess it's something with the heat or the coolant. I don't know.

Sounds like it comes from the right side? Anyone else hear it and know what it is?
Geez, I love motorcycles. I can pretty much identify most any sound they make. Plus, I'm just not THRILLED with the acceleration of this thing like so many others are. Ahh, 2 wheels are SO much better than 4....
