I will want to keep my warranty and use HD parts except for Fullsac head pipe but the numbers are disappointing. My HD with the 117 kit and torque 285 cam, Fullsac head pipe and fullsac 2" baffles ( using what was then a legal HD Race Tuner) 117hp and 126TQ). I would think a 4 valve head alone would achieve much better numbers not to mention the added cubic inches and factory stated increased compression ration. Not trying to be buzz kill what what's up with he m-8?

Exactly
And to run the kit you have to use the cat pipe from HD. Break out and use other pipes and now its a custom tune and no warranty.
You said

True but then you plug it up intake and especially exhaust and not give it the compression needed plus use a less than ideal cam what happens?
You get the sum of the parts and tune!
FLSTFI Dave:
The 131 kits I have seen are coming out very close to 123 HP and 138 torque with a nice torque curve. That is using all Harley parts and keeping the warranty. Its really nice torque for a guy that wants warranty for two years and to be able to ride cross country.
I have seen a couple with other head pips or tunes. HP did not break 129 and torque is in mid to upper 140's. But no warranty.
Iceyone:
I used the pistons, jugs and cam, i kept the stock heads (sort of a test case for the dealer) kept it under warranty, and pulled a 128 hp and 149 tq, these numbers beat the bike he did befor e me, the other bike used the whole kit except head pipe, he used a 2-1 bassani that actually robbed it of power, he pulled 135hp and 146 tq, i now have the fulsac CVO 2.5 exhaust in my hand and were gonna see if it does make a difference
