New owner in Chicagoland

Welcome aboard. You can physically look at your ecm to see if a "race ecm" was installed. It will say on it. It is highly unlikely- since the stock one is tuneable as well. Sounds more like the situation that Mope described above.

all tell-tale signs of a buell that has been ridden "hard" shall we say. not necessarily abused....but alot of WFO and trips to the rev-limiter. i would spend a few evenings with a shop manual(free to download on this site), familiarize yourself with both it and your new buell, and go over every fastener, adjuster, fluid level, cable tensioner, suspension fastener, braking system.
to answer one of your questions EBC HH pads highly recommended for XB's. i sell them to board members if you can't source.
