Hi all, My 12K service is coming up and it's air filter replacement time. Now considering the stock filter is going to set me back about $85, I'm looking at getting an aftermarket reusable one (like K&N/BMC or something similar). I'm not looking for any performance gain and don't want to change the mixture in anyway that would cause the need for a remap etc, just looking to save some cash in the long run. Also, the bike is completely stock at the moment. No? Yes? Kittens?
