Dolmar/Makita 7900 muffler mod only vs woodsported (oregon exl chain)

Quick match with the new oregon exl powercut chain in dry beech wood. The original 79 is stock except of the wojo dual port muffler (and will also be ported soon). I took the chance and put it against a freshly ported 6401 with a 7900 cylinder kit.
