i am currently in afgahnistan right now but am soon going on mid deployment leave and i bought some mods for my 08 xb12r like D&D exhaust and k&n air filter and im changing out most of the plastic with carbon fiber except for a few small parts and i had my mom talk to the harley shop a i am not home to do it and the guy said about 1200 dollars to pute all the stuff on and there were some other things the guy told my mom but unfortionitly she did not write them down and she is not mechanicly inclined so her trying to tell me what he said was horrible can any one tell me what might needs to be done to the bike if i pute a D&D on it and K&N because the harley shop said they never did it on an o8 before
