I'm getting a worrisome clank. I thought it was coming from the rear of the bike, but my hearing is not what it once was. I couldn't find anything loose back there. The Norden 901 FB page has a couple of guys that found their steering head bearings to be loose. Anybody had the same problem (or heard the same noise), and if so has anyone tried re-torquing the steering head bolt? Mine seems to be torqued correctly, but now that those other guys on FB made mention of the loose bearings, that is what the sound sounds like.
