Has anyone ever had problems with their sprocket bolts on the '00 yz's? I bought the bike, and noticed that the bolts kept coming loose. I ended up replacing the sprocket and getting new bolts...I made sure to use lock-tite as well. I made sure that I checked the bolts before every ride with the new setup. Well, on about my fifth ride with the new sprocket something weird happened. I landed a jump at the local track, and suddenly heard a loud noise and had my back wheel sieze up. I look down and find my sprocket bent in half with part of the hub torn off and the spokes broken. After taking it apart, I found only 3 of the 6 bolts still in the sprocket (with the hub still attached...sorry to say) Anyways, I'm almost positive this happened because the bolts came lose again. Has anyone had similar problems? I'm getting my wheel rebuilt, and would hate for this to happen again because of bolts coming loose. Any suggestions or info?
