So we did 2 pass today racing side by side 2 atv, it was in heavy soupy clay, so anyways on the second run it made it then on the way bck I heard some clunking noise, ofc I held it still wide open, its a race so anyways when we got bck in the heavy stuff heard a loud toc and stripping noise and the bike stopped moving so assuming over time my chain stretch to the point the automatic tensioner got max out and snap the chain any heavier duty solution out there
