Yesterday I was getting a pretty annoying and loud clunk from my TR450. Today I fully disassembled it and gave it some TLC. I noticed that every single bearing felt awful, including the large pivot bearing, really notchy and not smooth. I got the frame last October, rode it a little in the fall, put it away for winter and have about 10 days on it so far this season so it really hasn't seen a whole lot of use and it's very rarely ridden in any kind of moisture. I was able to pull the bearing seals off and pack them with grease, most of them came back to life but a couple are still pretty notchy. Is it pretty standard for bearings to come dry? Maybe I should've torn it apart as soon as I got it and packed all the bearings?
