Remove visor from TR06RR

[KirinXHell]

Need help on removing visor from a TR06RR.

 

Unlike normal HJC helmet where you can push the clip and it will release the lock on the helmet visor, the TR06RR have 2 black stopper/screw that set the visor in place.

 

Tried to turn the black stopper/screw but it became abit dented which I think its impossible.

 

Remove the cheek/ear pad and notice that the Styrofoam is blocking the end of the black stopper/screw.

 

Have search the whole internet but to no avail as most of the video show is using the quick release clip at the side.

 

Need to know if anyone have remove such helmet visor before, and how to remove it. Thanks.
