If you want to check chain drive adjustment
First You will have to mark middle chain lenght
Then in appointed spot measure range movement. Check the highest and the lowest position of chain. Difference of hight between those two will be your current range movement. Right range is 20-30mm.
Bike should be on the side stand
You can also check chain range movement when you sitting on the bike. Then also range movement shouldn't be too high or to low.
When bike is on the center stand, you can also check general look of the chain. Search any rusty places. Check also chain tension in various places - it should be the same everywhere.
Check also condition of your rear sprocket.
Last thing to do will be attempt pulling the chain from rear sprocket. If you can pull chain from sprocket more than 1cm that indicates that you will have to replace chain.
