I have a 103 with head work and big cams. I average 43 mpg if I don't hammer on it.

Anyone thinking of an upgrade should consider the stage 3 kit with the Super Tuner included.

What is in your build, what pipe and air breather ( stage 1 ) cam ( stage 2 ) head work, compression, ported & polished or not ( stage 3 ) differnt cams than pervious build and /or supercharger/ blower ( stage 4 ).

Well I'm sorry guys ,minutes later I looked on hd site for all 103 kits and all include jugs and pistons

I wonder why the guy would have said that? after all I'm still relatively new to harley's and all things motor upgrade wise some A$$holes just gotta put one over on the unknowing I guess it makes him feel smart.

I just did a 95" upgrade. I installed pistons and cyls. and 211 cams. Also did the carb rejet. I would be leary of having those guys do the work if they can't tell you what is really happening. I think you would be quite happy with head work, pitons&cyls and cams. Be advised, you'll need to get a remap and possibly change ignition module and get it dynoed to realize it's potential, however, the difference in performance is substantial but longevity will remain good with that particular combination. ps you'll be impressed
