Well, here's a timeline. Bought the bike, it ran fine. About two weeks later, it started running rich. Still ran fine, just could smell gas in the exhaust. Someone suggested I check the air filter, it was wasted. So I ordered the K&N, and the PCIII. Checked the bike again before I started tearing into it, it ran and idled fine, still smelled like gas. Keep in mind my fuel mileage has not been bad at all. I replaced the filter, installed the PCIII, starts right up, runs fine, it just idles really rough and was running lean. I upped the fuel by the buttons and the idle smoothed out a bit, the pinging went away for the most part. I rode it to work today, it ran perfect, it just has a terrible idle. It even seems to have a lot more power at the bottom end. I will pull the tank and check for connections under it when I get home tonight. Considering I'm looking at $250 for dyno tuning, I want to make sure everything is perfect (or as close as possible) before I do that. My temp tag expires the 21st, this just seems like I'm going through a lot on a bike I've had less than a month.
