Yes, it rains often here and I have to ride through a monsoon on occasion. The last thing I want is for the bike to ingest enough water to cause damage or premature wear/failure. When cleaning the previous filter I noticed a white ring on the frame where the filter sits (as well as whole bugs, leaves, and other various debris stuck in the filter). Looked like water had sneaked past the factory seal and sat there until it evaporated. If that can happen with the seal in place I'm wondering how much water and other stuff is going to get in there without the seal.
I have a Kawasaki as my #2 bike. It has an aftermarket intake installed with a K&N filter that is completely exposed. I park and throw a plastic bag over the intake if it rains hard.
The XC is my long distance bike. Don't want to park if it starts raining hard... put on the rain gear and keep rolling.
