I just installed the Lightech chain adjusters on my 2017 R6 and had a couple of issues. First, because of the way they're set up the axle now goes in from right to left. No big issue as several bike manufactures have their motorcycles set up this way. The second and more significant is that the axle nut will not completely seat. The adjusters take up just enough space that the nut will not go down all the way. I could remove the washer and may get it down all the way but I just wanted to know if anyone else had this issue.
