Hi devon and welcome,
finally, a photo of the entire bike. The photo tells me that your runaway throttle problem has a lot to do with a sticking and too-short throttle cable.
The too short fix could be at no cost if the twistgrip was turned so that the throttle cable points down instead of up.
The sticking fix takes cleaning, re-lubricating and re-routing the cable to take the kinks out, especially that sharp turn into the carburettors.
As to the rest of the bike, oh dear me, where to start? the extra fork gaiters ABOVE the lower triple tree fer fuxsake?
After my son had stopped laughing at that he said "I'd get the frame welds checked before I rode that bike anywhere because the guy who built it
didn't have a clue."
