I have an 2005 YZ250F and it seems that everytime I go around a corner at low RPMs the chain is clakking??????... I cant seem to figure out what the hell it is!!! I thought it was the chain on the chain device but its not that.. I have new sprockets and chain.. tried 2 different tensions on the chain... Nothing seems to work! Could it be internal? I'm new to MX but it seems that sometimes when I'm shifting and I guess it misses the gear it goes into neutral?... is that just a miss of the gear or how much does this happen? I know that the noise is coming from the chain area.
