I am posting this because in the 3 plus years I have owned my bike no one person could give me a straight answer. Everytime I asked I got a different response. So I will post this data to be a fact as I have torn my motor down and have had everything measured. The only problem you may have with your 04 117 is the production date. My production date was april of 04 so chances are if your bike was made after that it has the same configuration. There are still some who say that these are non epa motors but I doubt that at least after april. So here it is and I will give comparisons to my motor and a standard S&S 117 motor.
BIG DOG /// S&S
bore=4.125/// 4.125
stroke=4.375/// 4.375
compression=9.6/// 10.2
cylinder height=4.929/// 4.886
head cc=89cc/// 89cc
cam=.547 /// .600
intake valve=1.940/// 2.0
exhaust valve=1.575 /// 1.625
also a notable mention because the camshaft has such a low lift standard evo lifters were used so you have to install lifters with travel limiters or at a minimum some washers(which do the same thing) also called restrictors(back in the day) to limit lifter expansion.
