Good to know, I'll have to take a look at that. I think it is the air filter though. Yesterday I pulled off the tank, cleaned the fuel filter, and then tore into the air filter and when I pulled off the cover it looked horrible. I cleaned it, let it dry, and the bike is running a lot better but still not where it should be. I'll update in a couple days when I get the new air filter and go for a test ride.
