I've heard oven cleaner does the trick.

Alibrite from Supercheap, but don't get it on yourself and wear safety glasses.
Looking for YZ250C parts NOS if possible

take it to an anodisers and get them to reverse it.

Lot of effort for a sprocket.

Surely buy a new one.......?

I use this method ....use a phosphoric acid bath at about 20 precent phosphoric acid to 80 precent water (1 gal. of acid to 4 gal. of water ratio) heat liquid to 190 degrees. then submerge part depending on size for 1 to 3 minutes.

I also use citric acid to clean rims

Oven cleaner is Caustic based ....

I learned that one the hard way when I mistakenly (don't ask ) used garage floor cleaner (caustic) to remove some rock hard mud'n'stuff from my wheels. The result wasn't pretty.
