Awesome! I like the HP over TQ. 147 is plenty strong and 16X ought to fly up top. :clap:

That's a great motor I run the same one in my Dyna.
Its a Zipper prepped Merch base producing very similar numbers all day long. Oil coolers a must where I am at.

Considering the weight of a FXR, that should be a handful.
