The biggest concern is going to be tuning the thing. HD seems to think that a blank ECM is needed, so that the blank can then be flashed to a stock 114 bike. The 114 has a longer stroke than the 107, so, in theory, the crank position sensor wont even be reading properly to the 107 ECM, right? So, this is going to be an interesting venture.

Crank position doesn't change because of stroke length, 360 degrees is still 360 degrees, and the events timing doesn't change because of longer stroke.
