I'm not sure if this is a bad dream or something I made up, or reality but I could swear I was able to bump start my second motorcyle going backwards. When you did it it would run in reverse instead of forward.
It was a 60cc yamaha street bike. 2 stroke, oil injected, I believe a '72. Maybe older?
I think this really happened. I was sitting on our road. It was pretty steep. Pulled in the clutch and drift backwards, down the hill a few feet and pop the clutch and it would start in reverse. Then you would turn around and face the bike down the hill. Give it some gas and dump the clutch and you could do a smokey burnout on the hill slowly going up it, BACKWARDS.
Maybe I just dreamt that......It seems so real. I was around 9 years old when I had that bike.
