I replaced mine yesterday, I think I did it slightly different from other methods on my '11 bike.
1) Remove the three allen bolts that hold that plastic cover on the tank.
2) Remove the allen bolts holding side fairing. You don't need to remove it, just loosen the bolts and pull fairing away so you can get your hand through under the frame to yank out filter.
3) Remove three bolts that hold black trim and glove box.
4) Remove two bolts that hold filter aluminum strip
5) pull out relays out of foam thingy that is next to tank.
6) relay bracket, just remove one bolt and push the thing to the front of bike as you pull out filter.
I have never done this before, took me about 25 minutes. No need to mess with the position of the shield, no pop rivits to remove.
Bike idles better, feels smoother and more powerful. My theory is that if you have a four cylinder car, the C14 filter probably will last 25%-50% as long as the filter in that car. I say that because the engines are sort of close in size, but the C14 is inky dinky compared to what is in my cars, looks more like a filter for a large lawnmower than a bike, with small pleats and small overall size. The thing was pretty dark, no flies or strange bugs smacked in it, but just black looking. On my last trip last month, my mileage was down from I usually get, even in eco mode and I bet it will be better now with a clean filter. The dealer wanted $43 for the thing, next time, I'll either try to source aftermarket paper or even consider cotton gauze (no K&N vs paper arguments, please).
