so I got all those problems fixed and i had it running it started first kick. i broke it in with heat cycles and after that I went for a little ride. it rode great for about 20 25mins i didnt even take it full out yet and i heard a lot grinding coming from the bottom end i turned it off as soon as I heard it. it feels like the crank moved out of place or something but it still kicks i only half kicked it because i didnt want to break it. but what could have happend?
