So, I have had this bmx up and running for a few weeks now. I kept the tires on the ground for the first week, to let thing settle in a bit and I'm still adjusting to it as well. The next week I started lightly hitting curbs, to shake anything loose and re-tighten stuff. The week after that I started hitting things a little harder and jumping more frequently, I've probably pulled six feet of air on this thing at most.
My headset started making that creaking sound that I have read so much about. Everything was and still is tight, when I took apart my front end to check and clean everything the top bearing was fine. And bottom bearing seemed to me like it was starting to ovalize on me, it was hitting on two sides when I removed it out of the headtube. When I popped the bearing in new, it didn't seem to rub on the headtube as much as it did on on removal and re-installation.
It's a sunday headset if that makes any difference. Is that just how these things are? Shits tight, like nearly overtightened. It's dry, head tubes clean and free of debris, bearings are smooth as butter and it started creaking on me again the day after i cleaned it. There sealed bearings that just pop into place, does the headtube need grease?
