Not as much as it should have for the size bike it is. I've senn them range from 68-74 in stock form, all dynos are not created equal, and as stated earlier stage I will give you about a 10% increase.

 

Formula for computing horsepower:
:: Torque x rpm ÷ 5252 = horsepower
For computing torque when horsepower and rpm's are known:
:: Horsepower x 5252 ÷ rpm = torque

 

My 12' SG was 73.99 HP and 90.62 Torque from the factory after a very careful break-in.

The Kuryakin High Five Mach II air cleaner and Vance & Hines Big Radius 2-Into-2 exhaust, and Screaming Eagle Race Tuner brought those figures up to 85.8 HP, and 99.21 ft/lbs on the torque. That is with the V & H pipes stock, with no baffles added. I have since added the Thunder Monster QQ baffles, and will be doing another dyno tune in the spring. I expect there to be a few more HP and ft/lbs due to the slight back pressure increase from the baffles.

I will post the results when I get them.

 

Yea but they do run lean out of box. PV or master tune to get it to 1.21. Roflmao that you caught that!!
