I am out of the race game and now found a couple of older chains I used to use. The 1/2 inch is 62 DL and .063. It was built for the 500 Kawi saw I built and has an Art Martin sharpening job. The 3/8 is 84 DL and .050. Has been lightened and also was sharpened by Art. Put this on a saw and it feels like it gained additional horsepower. $250 delivered anywhere in ConUS.
