That’s not how you break in an engine, low rpm on and off the throttle lightly. that’s how you brake the engine my friend and have rebuild it again and have to break it in again, but it’s a Chinese bike so to hell with it

[@handsomefingers7759]

Before that it idled for hour and i changed oil. This was first drive break in
