I have the Air Shammee and love it. I bought the attic mounted version (less clutter in the bay) and haven't had any problems with it. Definitely need to market it to your motorcycle customers, they love it. Call Pat at Diskin Systems,
www.diskinsystems.com, and he'll take care of you.
One thing I didn't purchase right off the bat was their handle with the fan tip blade. I found the one with the round hole made it difficult to control the water. Then I bought the handle with the fan tip, it pushes the water off a lot better.
