[QUOTE="zawetzel13, post: 1114402, member: 73263"] I have a 2000 CR125. I just rebuilt the top end with new piston and rings. I was breaking it in and had about 6hrs on it when all of a sudden it started banging like crazy. I shut if off imediately and took the motor apart. I got the whole top end apart and everything looks good. no scrapes in the cylinder, the piston and ring looks good, no metal shavings anywhere. I put it back together and started it up. it still has a very loud banging noise. it does run, but sounds just terrible. I then tore it apart to look at the engine again and still nothing looks wrong with it. One of the reeds has a chip out of the corner but not even big enough for air to go through. could that be causing the loud banging or would it be something in the bottom end? note: banging is constant whether in gear or not, oil level good. no visible signs of wear or anything in top end, powervalve works good. Anyone who has had this situation or any suggestions please comment. thanks, Zane [/QUOTE]
