This will be saved for one of those fall weeks when it is just too miserable to go outside but the man-cave/garage is still warm enough that my fingers haven't lost their feeling. I'm going to replace the grenade with 2 steels and one friction to make everything stock, and I'll replace the stock throw out bearing with a 7200B bearing at the same time. I'll post the results then.
I found the time on some cool mornings last week to replace the throw out bearing and the grenade plate. I posted the details of tools, steps and results in a separate post. I hope this helps some DIY riders. It is not a hard job if you take your time, plan well and have the right tools. If I could do it, anyone can.

UPDATE:
Nearly 2000 miles later, the new throw-out bearing and grenade plate removal continues to make rides more enjoyable than ever. I ride mountain twisties all the time it seems I shift every few seconds throughout all of my rides. The smoother and easier clutch pull (to me, anyway) and slightly quicker clutch engagement are far better than what I had before, which weren't that bad in the first place and the parts I removed were still in very good shape. So I figure went from "good" to "better". I encourage everybody to do this. It's not expensive, not hard to do and the only special tool I needed was the clutch spring remover.

Does anyone know if the new EFI Sportster's have the same spring plate and clutch throw out bearing?
If I ever decide to add a new Sportster to my garage, I would definitely replace these like I did on my current 2005 model. These mods, along with my external crankcase vent and manual petcock mods, are the best things I've done -- so far.

Well the 2017 has it. I suspect nothing has changed from your bike to the newest.

All Sportsters 1991 to present use the same spring plate 37977-90, EXCEPT the XR1200 which uses the judder spring setup from a Buell XB.
The XR1200/Buell XB judder spring parts can be installed in an XL, did this myself and it works well, spring plate is gone and no clutch squeal when taking off in first gear.
(I tried the two steel + 1 friction plate replacement for the spring plate first and got a VERY annoying squeal)
That fix plus several other options are detailed at
