I hd mine dyno tested when setting up my power commander and it made 44 hp @ 6000 and 46 ft lbs @ 5200. after thunder air kit vh cruiser pipes and deleted pair valve it made 53 hp @6300 before hitting rev limiter and 51 ft lbs @ 5000 and still had 48 lbs at 6000. it could meke use of taller gear. with a dj gear drive it should get 130 mph, if if will pull max revs in fifth. with stock gear it will probably get 120 with prayer but it accelerates much harder and still docile enough for cruising around. I hope this answered your question
