What is your thought on K&N air filters? I had one on my GL1500.By the way, it's worth mentioning that the air filters in these new generation Wings seem to get dirtier a lot faster than the previous generation did. Here is one I pulled out of a different bike yesterday, with around 18K miles on it. I've done a lot of these now, and every air filter I've pulled out has looked pretty dirty at relatively low miles.

From valve adjustments to air filters.
. Interesting that you have to "undo" exhaust adjustment to do the intake adjustment.
