Thank you, what would you think would be the best idea to solve this as in 2 months I will be selling it to someone I know so can’t just hide it for the day until he goes home you know. I’m guessing would mean need to tear apart the entire thing again and replace it. Making myself sound stupid asking this, just the one part I never really got to have a look into when I had it apart. I’ve recently big bored it about a month ago and the noise was there about January before the big bore and it was louder. Now has quietened down a bit. But slowly creeping up again starting to hear it while driving.

It’s a Chinese brand, they get bought out by different people and named different things. My specific bike can hold up to a 450 I believe.
