Here's my Hotsaw cut at Squamish. Had the saw to beat for sure, 138cc Honda, but things happen. This is a cold start 2 cut race in 22" douglas fir. They measure your 2 cuts after the run and they can't be thicker than 4". In my case 3 cuts couldn't be thicker than 4". Winning time was 11.8 Hotsaw limited to 140cc, any type engine, any fuel.
Just watched the videos, looks like a fun competition. Congratulations on your win. Can you post some more closeup pics of your saws? You have some cool looking stuff.
