most of you won't believe this, but here goes..........its pointless to lube an o-ring chain. During assembly of a new o-ring type chain, its packed with thick high temp grease, (between the barrels and plates) and then the o-rings are installed to keep the lube inside (permanantley) and also keeping moisture and dirt from entering. It is important to keep the chain as clean as possible (safely, with out harsh chemicals). But...once you start adding a spray on lube, the cycle of self destruction to the chain and o-rings begins.
If the guy at the parts counter can sell you a can of lube, ...he will, even if it says "o-ring safe", (its the propelant, not the lube that does damage).
O-ring chains became popular when other bikes were being made with a maintainence free drive shaft, so those models that require a chain had to come up with something, and the o-ring chain it is. Also, the manual tells you to lube it now and then, and thats to prevent it from rusting.
Think about it,...if your lube is getting into the chain, then the lube that was once in there has gotten out, ussually from a cracked, split, or missing o-ring, and at this point, the chain has probably met its normal service life, and its time for a replacement, (but only with new sprockets of course).
