This was my third ride on the build. Put a little to much oil in (don't knel If it caused the problem or not.) was riding all day long. I was on a kinda steep hill stuck on a bush. Popped it in first trying to run the bitch over. Almost stalled piling out saved it then the idle dropped I gave it gas with clutch pulled in barley running and back firing. Running like **** and shut it down. Towed home. Any ideas on what happened?
