I'm one that doesn't buy into the "WD-40 kills o-rings" claim. The MSDS on WD-40 lists that it's primary ingredient is an aliphaltic distilate which basically means something very similiar to or maybe even Kerosene.

All I can say about that is that my last chain never saw a single drop of lube for it's whole life...18K miles and I changed it... all free links with all of the o-rings in place and looking good. Turns out the spec Yamaha provided for chain stretch was so conservative that even my new OEM chain exceeded the wear spec out of the box.
