For what it is worth. I did the 117 SE kit on my 2017 Low Rider S. I went with D&D Boarzilla exhaust and upgraded clutch. Bike still has factory warranty. On the dyno, it produced 120.67HP and 128.54TQ. I figure when it is out of warranty, there is plenty of room to do more. For now, it was an approx 50% increase in HP over the stock 80hp or so. It runs great, and pulls strong.

What a beast...congrats!

 

Keep going back and forth to do the same to mine. Do it yourself?

 

Killer Creek HD did it for me. The bike only had 1000 miles on it. It is a completely different bike with the upgrade. 50% more HP. The D&D Boarzilla exhaust is load, but I was going for performance. One of the important things is the tune once the work is done. Big difference going with a plug and play tune and having someone work with it on the dyno. The tech at Killer Creek, Abel, is awesome. He took his time and the bike has a nice flat torque band. It keeps pulling hard about as fast as you want to go!

I'm in Cumming about 30 minutes or so from Killer Creek. If you don't mind me asking, what was the damage to the wallet having an HD tech do the tuning?

 

If 80HP is stock and you have 120HP now how's that a 50% increase? Sounds like a rocket, just confused on math but it could be me.

 

80 + 0.5*80 = 120

 

Didn't intend to be confusing. 120 is 50% more than 80. 80 + 50% (40) = 120.

 

 

What cams did you go with?
