cache: won't wd40 hurt the o-rings? do you clean it when the chain is cold or warm, or does it matter?cleaner: wd-40
oil: 80/90w gear oil.
the weight of the gear oil helps keep it from slingin' off. want to use a lubricating cleaner too.
Where do you get the Amsoil product? Thanks Kevin.Amsoil makes an awesome product. Goes on like penetrating oil, then cures to a wax consistency. It is Amsoil MP/HD. Part # AMH-SC retails for $5.75 a can plus shipping. No sling off!
