82 GPz750 - Drive Chain/Sprocket Questions

Getting near the end of getting the GPz road ready. I purchased this bike in the beginning of June. It had sat for about 9 years with the second owner. I'm taking the wheels off today to have new tires installed. Now that I've done the brakes and the tires, the last thing I have on my list to address with this bike is the chain. It appears in decent condition. It has a master so I'm assuming its not the original endless chain. If I replace it, I imagine its a good idea to change sprockets also. Speedo mileage is 19.5k. Thoughts? Also, do you guys run chains with master links?
Thanks

I always replace chain and sprockets as a set, otherwise like of them will be much shorter. I've never had a problem with a clip style master. Maybe someone has?
I would buy a sealed O-ring chain, well worth the couple extra bucks.

I've run master links for 30 years without problems. Z1 Enterprises has the best prices on good X-ring chain and sprockets.

replace everything at once, you might want to upgrade the chain size to a 530 instead of the 630
