I previously have had good results running Xieds on my 3 previous bikes (08, 13, 16 Streetglides) and now I'm wondering why not put them on the 17? I know with all the talk about voided warranties, it would definitely be something you would want to take off before having the bike serviced. Has anyone tried them on a 17? They always cooled my engines down, gave better throttle response, and was ok with my stage 1's before I would start fiddling with tuners. I would think they would help a stock 17 even run better. Any thoughts?
