Quoted from klr650:I just bought 100 Chrome Ninja balls from the Ball Baron. I love the Silverjets but the Chrome Ninjas are a far better value.
Since I will have these for some time I was a bit worried about eventual oxidation / corrosion during storage. So I placed them in a plastic container and then topped it up with some fresh engine oil. Should be good for a very long time...
Do you regularly soak your balls in oil?
