I have a 2017 FLHTK and the dealer is doing a warranty rebuild of my motor due to an excessive oil consumption issue; so it would be the perfect time to do it.

Two questions come to mind;
1: Is the performance improvement noticeable enough to justify the cost?
2: Has the change affected anything else about the bike, especially reliability?

Thanks for the help.
I bought 2017 roadking with SE stage 3 dome at factory. lots of performance if you want it to start at about 3100 rpms. 24000 miles and runs great. replaced cam with zippers 468. torque starts at about 2000 rpms. Matt Laidlaw has you tube video on the stage 3. really informative.
