So today it started to do knocking noise...went to watch motocross with rainy weather and when I rode home, halfway I noticed it started to do the nervous throttle thing again(when I let go and then throttle again) that it didn't do so agressively when cold. Then under traffic lights I heard knocking sound from engine.
Its knocking randomly, starts to knock more when I use throttle as you can see in the video.

When I used front brake and then loaded the engine it started to make more noise.
I hope its the nut from crankshaft...otherwise this season is kind of over...
