Break In How to properly break in a motor

I found there not really broken in until you get about 800 miles on it then you get a notice speed increase and better hill performance.

There is absolutely no possible way you or anyone is getting anywhere near 100 to 120 MPG with one of these 66cc or 48cc or ANY cc motorized bicycle engines, no matter what brand it is, or what modifications have been done to itand/or gear ratio Ever.

Maybe 12 yrs ago they were getting 120, I myself get about 100 , but it's 2021 so maybe that makes a difference. Who really knows.
