The old scoot ('07 FLHTCU with 116k right now) is going to be due for an engine overhaul this winter. It will be close to 125k when the riding season is over. The engine has never been opened up and the only mods are a SE air cleaner and Rinehart True Duals. We do a lot of two up touring and occasionally pull a trailer as well. My considerations for the overhaul are: 1, maintain reliability. 2, more power. 3, preserve reasonable fuel economy. Any thoughts or recommendations?
