Grand Rapids HD, Michigan. When bike was in for crankcase replacement under warranty, I had them install SE255 cams. Tech didn’t push any downloads or tuners. Tech actually made adjustments to my EJK Gen3 when finished. Service was great. Also to my surprise when I got home I noticed my primary (derby) cover was replaced with a new one. It got scuffed up when I changed fluid. Service writer did document it was bad on incoming inspection.
