That's really not so uncommon. I think it's more of a rider thing than a bike thing. Generally the big Harleys have more torque than HP. And yes, Screaming Eagle parts help. I keep my 03 Fat Boy's 2 tires on the ground. It started life as a stock 88 (1450) with 58hp (sad but true) at 65mpg. It now lives a much freer life as a better breathing 95 (1550) with a 204 cam, Vance & Hines 2 into 1 Pro Pipe HS and Stage 1 intake setup. It was dyno tuned with a Race Tuner module to 84HP and 94 Ft Lb of torque. That guy probably has a 103 stroker kit in that big mother. I consider mine to just be mid level performance. Quite a bit more HP and torque can be had with these engines.
