Chain Lube Type and Frequency?

[Toddman_imp]

I'll chime in. I did somewhat of a test on an old 2003 ZX12R that I purchased new. Since the chain is o-ring sealed, I carried a 35mm plastic film case with plain jane bearing grease. I used WD40 to clean the chain and bearing grease for the lube. When the chain showed dry, a one inch section was dabbed with very little grease. It will distribute on it's own. I got 23k miles out of that chain. The ZX12 has a lot of power and i used the power regularly. I thought 23k was decent. The links started binding/seizing but the sprockets looked very good.
