WD40 IS NOT A LUBRICANT
You will significantly lower chain life if you use it for anything other than cleaning (not my opinion, several magazines have done chain lube tests over many years)
Use a dry lube or normal chain lube but let it 'dry' overnight
If your worried about bike getting dirty, your definitely in the wrong game :
The outside of a chain needs no lubricant. D.I.D. says to use chain lube to "protect the chain from corrosion." With an O or X ring chain, all the bits that need lubricating are sealed. You couldn't lubricate them if you tried.
WD40 is not the recommended protectant, agreed. But I put some 8K miles on the X-ring chain on my big Suzuki with no appreciable wear (it probably went much farther, but I sold the thing, so I can't tell).
Still, all that is needed is some manner of corrosion protection, and for this D.I.D. recommends a light chain oil, most of which is then to be wiped off the chain. Those sticky, nasty, gunky, snot-like "chain oils" quickly attract and hold dirt and grit, turning into something more closely related to valve grinding paste that any sort of lubricant.
What are you trying to lubricate anyway? As I said, all the bearings are inside the sealed area of an ) or X ring chain. The outside of the roller needs no lubricant, it "rolls" in and out of the sprocket. You don't pour oil on the outside of the engine (unless you ride a British motorcycle... they do that for you).
As for getting my bike dirty, I never mind that. It washes quite well. But I prefer to keep lubricant in the areas that require lubrication. Engine oil goes in, not on the engine. Transmission or primary oils go in those places, not on the outside of the cases. Bearing grease goes in the bearings (like the chain, the newer ones are sealed). I can spray all the lube I want to on a sealed bearing, but all I accomplish is making a mess.
