I also have the flhrsei2 se pipes ,filter, and race tuner. Bike dynoed at 95 hp and 100 ftlbs torque.I am still in search of more power.Frederick harley in Maryland tuned it for me.I was talking to guy today who claimed to be a dealer wrench in va.He said at his shop they put a 257 cam in a flhrsei2 with pipes intake and tuner and got 110 hp 116 ftlbs torque.Does anyone now the lift and specs on the stock cams on our bikes ? Also has anyone indexed there plugs with any benifit ? Port and polish throttle body? are there any bigger injectors ? Does any one have detailed specs of whats in our 103s ?I have a parts numbers book but nothing to copare with and alot of parts are new for the 103.Imo harley has probably done alot of research and development before they put these motors in production and they will be around for a few years to come. With more motors and forums like these hopefuly we can unlock the real potentual of the 103.
