I just bought a 2002 buell XB9R with 3,000 miles on it. I have been reading thought all of everyones posts. It seems like the PCV mod and removing the top of the factory air box and making a plate over the air filter is a must! What about hollowing out the factory muffler? I am a mechanic and a good welder. Will the bike run like crap, will I notice a powerloss? I just spent all my money on this bike so im on a tight budget right now. Factory exhaust is KILLING me! It sounds great at idle but like a lawnmower going donwn the street.
