I just got my 09 lightning xb9 and love it! A great bike and I plan on doing the mod to the exhaust and had a few questions. First how broken in(miles) should the bike be before i do this? And to be sure i do not need to do anything with the ecm? what about the tps reset? What will give me the louder sound(parts)? I also love the headlight mod which i plan on doing very soon. Not planning on much beyond that right now just want it to sound meaner than it does. Anyone know of a good seat as i find the one on the bike a little hard? I also did not get a ownewrs manual with my bike anyone know about the adjustable supsen. I weight about 150 if that helps with the settings. Thanks to any and all for help and love the site. LOTS of good info. Will post a pic of by bikes soon.(I also have a 07 blast)[confused]
