Thanks, didn't realize the CS3 used a Y-boot! My CS5 has 2 individual boots to the airbox. And the airbox is seperated as well, 2 filters and everything.

1" closed cell neoprene. Doesn't soak up water and you can sand it like balsa wood.

Do you have any online sources for it? I haven't been able to find any pads big enough for a seat.

Man, that is an unreal bike.  I have been looking for an old Ducati single to build a custom frame for and that is the exact look I am going for.  Very honored you thought so highly of my bike.  That bike is what motorcycles should always be about, cool, clean, and simple.
