Hello all ! My wife's 2005 TTR125 with a BBR150 has started to make a small knocking sound . I have been looking for a crankshaft kit for it have had no luck. I took the case sides off and it all looks good. I have had the BBR 150 kit on for 6months now and the last time she was on the bike it was just fine. I got it out two weeks later to just warm it up and that's when I noticed the sound. If any of you know where I can get one please let me know thanks !
