Engine help - possible rod problem

[QUOTE="SULLY, post: 739528, member: 30208"] Ooer...hang on, if you are 100% sure you heard metal to metal grinding, then you can be 100% sure there is something wrong. Personally, I would not run the engine again until I knew what it was. Take a real good look with a good torch into the bottom end. Look in the gaps between the crank lobes and the crank case, between the crank lobes and the con rod, and also in the oil slit in the big end of the con rod where you can see the big end bearing. Also look below the crank into the bottom of the crank case. What are you looking for?....anything that doesn't look right- any signs of heat blueing, particles of metal or burnt bits (I have had the thrust washers either side of the big end bearing break down on KX100's). Turn the engine over with the cylinder off, and listen to the bottom end, if you hear any any screeching, tight spots or greating then don't mess about, take it to bits and you will be glad you did. That's my humble opinion, but learnt through experience! [/QUOTE]
