Hi, can somebody help me please, I have a K8200 with lots of upgrades, a twin K8204 trapzoid, a K8203 1.75mm hot end as well as other things to help improve print quality, I just printed off a new fan nozzle and mostly I am happy with the print, except for one part at the rear of the print is very very poor

You might want to try adding support for those steep overhangs. Or lower the layer height in that area.

You need a better cooling fan/ system, but I bet you are printing this because of that
