My wife and I each own a FLHRSE4 Road King. I am not aware of any official 'recall' program for these bikes. H-D did offer owners the opportunity to have 'enahancements' performed at no charge; the enhancements addressed some issues that other owners have experienced...mostly with the 110" motor. There are posts on this forum that contain the actual tech documents involved; I would look for those. Neither of our bikes have experienced any of the problems, so we have elected to not fix what ain't broke (yet?...that is the accepted risk). There are many other owners that have many miles on their SE4's without incident. Your dealer can run the VIN# to determine if the previous owner had the 'enhancments' performed. I also believe there was a 2 year time limit on having the work performed...not sure if that is negotiable. Regardless, if you have no issues, I would just enjoy these wonderful bikes.
