Injeck is right the 103 is a custom mod for the engine, I think it is a stroker type kit with valve adjustments. If you are running stock, yeah he might have it for you. My recomendations is to get a custom pipe and computer, perfectly calibrated, that alone should be a very good surprize for your buddy. Also, I read somewhere you can work your gearing up a little to gain more top end. I just got my bike, and I'm still waiting for the technical manual, so I'm not that very knowledgeable on this particular bike. Iupgraded from a Vulcan 800, yes a girls bike, but it was modded extensively :)
Before I bought the Warrior, I was thinking on gettng a Dyna Wide, after ridding it, I was very disapointed, they are hogs, with all specifications associated with that name, big, fat and slow.
I'm still breaking in my bike, so I do not know it's full potential, but by reading this forum, convinced me on getting my Warrior, so i know you are fast, just let the Force flow through you, Do or Do not, there is no try...
