Just picked up an 04 meanie, it has 2 1/4 vance and Hines and K&N but it's running a little rich. Also it had a power comander on it but previous owner has taken it off due to low fuel issues with it. Aparenty it was sencing the bike was out of fuel but really wasn't. Now this is second hand word to me so that all I know. Any help appreciated.

 

Welcome to the forums. Congrats on the new ride.
So, the airflow in has been increased, the airflow out has been increased. Now the air/fuel mixture needs to be adjusted accordingly. That's what the power commander does. I haven't heard of a PC doing that, but it doesn't mean that can't happen. lol.... Purchase yourself a new pc, and should be good to go. Running rich, probably wouldn't hurt for a new set of plugs.
