I was 8 years old and it was Christmas of 1981. I got a Thunderbird Mini bike with a Tecumseh 4 hp pull start motor. Mine was like this but slightly different seat and tank and it was white no shocks either. I could ride wheelies and jump that thing really good. I also found the lever on the carb for the throttle plate I could hold it open and that little booger would get close to 50 mph. I am surprised the engine never blew on me.
