Stage 4 engine upgrade
I own a new 2013 Blackline FXS.
Doing the typical mods with slip-ons and probably a tuner with higher capacity air filter, etc. Considering going further in the future.
The question is: Will a stage 4 SE engine upgrade fit an FXS? HD catalogue only lists touring models for fitment. I imagine that the 58mm throttle body is the problem. Will it fit? Otherwise I will probably just change the cams at some point along with some other upgrades a la carte.
I have seen the other stage kits, but this one has the cams I am interested in. Plus, I don't want to go 110 CI.
