I would still like to do it myself, I just don't know which bike yet.... I have the Orange and Black original Harley Colours CVO Street Glide since last year, hot rodded with some goodies... And in July coming, the 11.5 BIG BLUE FLHTCUSE6 Dresser coming. If I keep both,

then maybe the SESG gets the 120R.... If I make the transition to the big full Dresser, for the auto locking top box and all the rest, then it is a consideration for it after I sell the SESG $E$G.
The point is you can hardly lose. You have a low kms motor chromed up sitting in a motor mount somewhere cool looking. And if you sell the scooter you can always switch back and put the 120R in the next scooter style you go to. It also gives you a second motor if something happens to one.
I still would recommend anyone attempting an extreme build, Stage 3 SE stuff or bigger, price it up, because at least here in Australia you are going to spend the same money on the build as buying the 120R motor. At least you have a spare motor AND that motor is worth some $$$$ that makes it worthwhile to buy the 120R instead of a total build. It is about the same money, only my way you get a low kms spare motor to keep for backup, or just look cool in the living room,

or sell to recoup some or most of the costs....
Tell me where I am wrong on this ..... Cowboy
