Kuan,
You really only change oil every 10K? Ew
BTW, I second G-Benz comment about the wind deflector. Since putting one on Casper, it made the difference between the defining roar you are painfully familiar with and the ability to carry on a normal conversation while traveling at 80 mph or even more. Got mine at
www.clairparts.com. Since buying mine, i found there are others that even have little air jets to permit you to aim some airflow into the cabin. Cool (literally)
