Roketa go-06 gear box removal

[KenC]

Like the title states I have a 2008 roketa go-06 and When I changed the fluids I noticed metal shavings from the reverse gear box.I could not find a gear box for this model but I did find a universal Chinese one that looks identical and bolt hole spacing is the same.i just need a little guidance on the removal of this POS lol

I got it apart this am,the shift linkage wasn’t adjusted correctly which caused the shift fork to rub against gear and that’s what the metal shavings were that I saw in gear oil
