I have a desire to install a Screamin Eagle Heavy Breather on a 2003 Road King Classic. Problem is I am not sure what the intake bore on my bike is, I think it may be 42Mil. SE dosen't make one for my TC88, Upgrded to Big Bore, TC95, EFI, Stage One, engine. Is it possible to do? Is there a modification that can be made relatively easy, and what is the bore on the SE Heavy Breather? I don't know if there is an adaptor out there that will make this possible or not, but if there is and I am able to get it installed properly do I have to have my engine remapped? Thanks in advance to all who respond with information. Ride Hard, Ride Safe, Ride Well !!
