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.

 

Hi from the UK and welcome to HDF. You're not in the best place to get answers to your query, so call into the Tech section, where there is an 'Engine' forum.

HDF also has some tuning shops who are sponsors and you will find them in there. Rather than buying stuff off the shelf, these chaps can improve your current engine and quite possibly save you money at the same time.
