Very Loud Chain

I have a 1980 KZ550. I noticed after a few weeks riding it, there was a slapping noise when I turned. Looking into it, the chain was really really loose and had been for a long time. I used the adjusters to pull the wheel back until the chain was tight, but not under major tension. I loaded the chain up with some light oil, and thought that was the end of it. However, it makes a clicking at low speeds, and when pushing the bike in neutral, it makes a lot of noise, almost as if the sprocket isn't meshing with the chain quite right. The sprocket looks good, do I need a new chain?

Yea man grab a new chain and also check for exesive wear on your sprackets.

sprockets i mean

Yeah, I guess I don't know how to check for sprocket wear, I need a new chain regardless, that thing is shot(had to pull the wheel like 2 in back to get tension?). The sprockets look OK, but might just replace the things anyway,

Sprockets should be replaced when thre chain is replaced. Sprockets and chain wear together, so putting a new chain on old sprockets will prematurely wear out the chain. Also, you need to look in the manual on how to adjust your chain. There is supposed to be a specific amount of slack in the chain. Too tight can be worse than too loose. If you don't adjust it properly your new chain and sprockets will be shot in no time. Ed

On the rear wheel sprocket, see if there is any bending of the teeth or "Hooking", a sure sign of needed replacement. As mentioned, replace both sprockets and chain as a set to ensure even wear.

Yes, and sprockets. Go to Z1E, best prices on chain and sprockets.

As suggested in response to your engine tick posting, you really should buy a Kawasaki service manual or you will waste a lot of $$$$ through the trial and error maintenance / repair approach. Please understand; I'm not trying to insult you. The manual serves as an essential part of any owner's maintenance and repair plan. In fact, it may be the single most important element in maintaining these bikes. I know that is true in my case. Ed

cant remember his exact name but its like load something but he has a downloadable shop manual for your bike it happends to be same year and size as mine and it has been very helpful

Perhaps the rear sprocket isn't perfectly aligned with the counter shaft sprocket.
Don't trust the alignment marks.
Best to assure equal distance on each side between center of swing arm bolt and center of rear axle.
Sight down along the chain over the rear sprocket to assure a perfectly straight chain as it leaves the rear sprocket and engages the top of the counter shaft sprocket.
There should be no discernible misalignment off the rear sprocket or onto the counter shaft sprocket.
Stated another way, both sprockets are supposed to be in exactly the same geometric plane.
Good Fortune!
