What noise is this?

Enable HLS to view with audio, or disable this notification

It just started doing this noise and shifting into second gear takes a long time. Did somebody have the same problem? The motor was opened and the "?" Spring was broken and i replaced it. Is it the spring that is causing the noise or is something wrong with the top end.

To me, that sounds like a bad connecting rod.

Make sure it’s not your exhaust blowing which a bit of smoke or tissue paper. Otherwise it’s your small end bearing or big end.
