*SPEED TEST* 40mph on a stock 66cc 80cc motorized bicycle

I take my Dyno Deuce out for a wide open top speed test. The engine has stock head and exhaust just smoothed the ports.
The speed limit of the big street was 45mph so I had a hard time keeping up with cars. The max speed recorded was 43mph.
