I got new sprockets with my chain from the local honda shop and when I went to install them today noticed the rear sprocket isn't right. The old one has reliefs in the back of the sprocket for the flats on the studs to locate to. The new sprocket (JT sprocket) is flat and smooth on the back with no way of lining up the stud. now to me this seems to be a bad thing as it would allow the stud to spin in the dampener in the hub and loosen the nut. What do you guys think? Wrong sprocket or wrong sprocket?? I can post a picture if need be.
