Default Hi from Kenosha

Hi, just got into motorized bicycles this Febuary, bought a motored Huffy from a 1st timer, then bought a motored micargi from a professional local builder, and more recently motored a micargi Falcon GT and also a 1966 or something Schwinn Typhoon. I put all Grubee 66cc GT-5 motors on my bikes, had problem with 2 motors so far: the small 10 tooth 'drive' sprocket has come loose on multiple occasions on one motor - this motor is now sitting aside. and now the motor in the shcwinn has the same issue after about only 250 miles..

I upgraded to the thicker sprocket to use with 415 chain.. using this chain/setup on all my bikes. Have single boost bottle setup on both bikes this has happened to. any thoughts, suggestions please?
