Default Removing Rocker Arm Adjuster Screw

I need help on how to replace the rocker arm adjuster screw. The threads were damaged when I tightened the pinch nut on the rocker arm. So when I removed the nut, the rocker arm also got stuck on the bad threads. The allen head on the adjuster screw is starting to strip out, so I need help on how to remove the rocker arm and adjuster screw to replace it all. I have pictures if needed.
Thanks

I'm sure that you could be helped with this fairly easily. It would help to know what year and model of bike it's on though.

Thank you for your response, it is a 1995, CBR 1000f. I am trying to attach pictures as well, but I guess I need to compress them first.

Attached are two pictures, the replacement adjuster bolt and a picture of the rocker arm/adjuster bolt in my head. The honda dealer said remove the rocker arm and screw the bolt down through the bottom, well I just don't how that can possibly be the case since the bottom of this bolt is round with no threads. Thanks for your help.

So I will answer my own question. After looking at the new bolt I knew that the old adjuster screw along with the rocker arm should pop out. I used an L shaped large needle nose pliers. The only position that allowed me to remove it was when I tilted the bolt as far as I could to the outer side of the cylinder head, it took a bit of upward pressure before the adjuster bolt popped out of its socket. Once removed I grounded each side of the round ball, then placed it in a vice. I gently put pressure on the rocker arm and it finally started to screw off the adjuster bolt. I used my dremel to cut the bolt and finished unscrewing the rocker arm towards the bottom.

Putting the adjuster bolt back in took a few tries but applying oil to the socket, putting a ratchet type allen head in the bolt and hitting it with a rubber mallet popped the bolt back into the socket. From there it is simply screwing the rocker arm and locking nut and then adjusting the gap.
