I have an '03 Deuce and wanted a little more low end grunt. Will the 95 CI kit provide a noticeable difference or is the 103 CI kit the way to go

 

95" kit from Headquarters or from GMR performance is the way to go. You will easily get 100hp and 100 tq from either one of those builds. You will have very little down time and you dont have to worry about making parts match for function and performance. With a 103 kit on your bike you will need to remove the entire motor, split the cases and have some machine work done, along with buying new fly wheels, rods. The 95" kit is way more bang for the buck and will perform just as good as the 103.
