Put new bearings and seals in my swingarm. I tightened the 2 allen bolts and the lock ring according to the manuals specs ( 80ftlbs ) went riding.. after about 60 mediocre miles the bolt without the lockring ( right side bolt,has a flange ) came loose and fell out. I did install it correctly according to the book!!! Now I'm going to replace the bolt, but I'm considering using the flangeless bolt and lock ring like the other side. Anyone see a problem by doing this??
