Those numbers seem to be lacking compared to what HD is claiming. Thanks for the information.

Too many updates to list. Let's say I've spent more in upgrades than I paid.... but how many times over is your guess.

My 1275 Hammer Performance upgrade http://xlforum.net/forums/showthread.php?t=2078737 IT WAS DELETED BECAUSE OF HAMMER'S SHODDY QUALITY CONTROL

Those power numbers aren't that surprising. Still heaps better than any sportster engine of years past.

Interested to see if the power plant remains the same or if it gets detuned for the following sportster models.

Seems legit to me. Harley is measuring power at the crankshaft. These are at the rear wheel.

Fashion over function. Hope they sell a bunch of them, not my taste.

I'll stick with my 65 hp iron.
