I changed mine once it was into the red. New 112 link chain took it right back to the black line at the start of the green. I changed the sprockets too as previous owner changed the chain but not the sprockets and that chain only lasted about 7k miles.

To check your chain wear, grab th link at the rear of the back sprocket and pull the chain away from the sprocket. I f light shows between the chain and sprocket, it's just about time.

Tip from an old British mechanic, change the front sprocket at expected 1/2 life cause it spins twice as often. Extends the remaining life of chain and rear sprocket. Also, use chain saw oil as chain lube. Its cheaper than MC chain and and formulated for the same job.

It does not show any light how are the chain does have a few frozen links. The chain and sprocket only have about 6,000 mi on them but the previous owner never cleaned or took care of them.

Frozen links ca be freed up. Lube with WD40 and work them as well as you can. Just riding may free them up. If there is evidence the o-rings are destroyed, time for a new chain. Keep us posted.
I decided to just replace the chain and sprockets. Now just waiting in some cash to get freed up. My friends asked if I was going to change up the number of teeth but I'm not sure yet. Still researching what the affects are of a smaller or bigger sprocket.

I added the 16t front sprocket. My son went different on the rear. We're both happy with the changes. You decide. 😁🏍

More than once, I've read that the OEM chain on the CB-500s is substandard, compared to the rest of the bike. I removed my OEM chain early on and replaced it with a top quality DID "Gold" chain which cost about $85 4 years ago. I changed the countershaft sprocket to a 17 (highly recommended) and added a Scottoiler. The upgraded chain now has over 12K miles on it and has had 2 slight adjustments. It shows no wear.

I opted to get a new set all together. Seems like the chain is toast. I made an adjustment last week and pulled the chain away from the rear sprocket at the 3 o' clock area and i see a big gap.

Now comes the question of do I pay for this or do it my self? I am mechanically inclined and seem to have all the tools. My mechanic is charging 80$ however I can put that money towards some stands or beer if I do it my self. Only thing I am confused about is do I have to cut the chain? Or can I r&r it taking the tire off?

You will have to split the chain ,either by using a chain tool or cutting with a grinder. Sprockets are dead easy you just need a torque wrench. Fiddliest bit is fitting the new chain with it's split link, ie crimping/peening the link with the chain tool and getting the gap correct. You will need some calipers to take the measurements and some confidence in the process.
