hey out there, any know if a 2013 103" from a street glide will fit into a 2002 FLHTCUI. properly?
Picked up the engine with 3500miles for very little. Thought I would pick it up anyway in case it works.

 

I'm not knowledgeable on the new harleys, but I believe you'd have to move most of the electronics from one of the newer bikes to yours. I'm not sure your ECM is "smart enough" to run the new engine.

But like I said, I'm not knowledgeable on these new bikes.

 

You would definitely need the wiring harness along with all of the associated sensors. Don't forget the throttle by wire, handlebars and the fact that you will need to install O2 senders in the exhaust. On less your trying to run a carb on the 103 somehow.

 

It won't even bolt up to your '02 tranny, let alone fit in the frame.
