Here is a video of me running a BP1 at our old saw contest at Baraboo Wis. I have posted this video before, so some of you might already have it. Just trying to save you from downloading if you already have it. This saw has 3/8 round chisel chain. It makes a huge diference in performance compared to the original self sharpening chain. This saw will compete at the Washington county fair contest (z4lunch) for stock saws 50cc and less. I think it might surprise a few people. At Baraboo, it was only beaten by a 1-55, and it was close. The year before we were cutting smaller wood, about 12", and it beat all geardrives.
