2016 CC. Not sure on mods. Just bought the bike, need to tear it apart and see as the previous owner wasnt real sure either. I have bought a llyods air filter. Looking into a pcv or maximus and eventually a cam and good tune. Current mufflers don’t sound stock but are definitely either a modded stock design, (my late father had one, and it was quieter than this one), trying to figure it out currently. Was looking into the Mutazu mufflers just for a little more sound, cheap and available. Then trying to get a remote tune. Currently the bike gets some soot or carbon build up on the back after riding a little bit, and pops on decel making me think its rich for some reason.
Coming from sport bikes and dirt drag racing world.. so I’m not new to performance, just not what I’m used to.
