I've stopped using the K&N oil filters now. I've heard of a few cases where they fail and leak. The bit with the nut attached fails and they leak everywhere. Happened to a mate on his Speed Triple whilst zooming round the alps! Was super lucky to both not lose it on the trail of leaking oil or seize up his engine... Some reckon they fail if you try to tighten them with the nut (which you should do anyway), but my mate certainly didn't do that. Dunno, could have just been a bad batch going round. Either way, I wouldn't want to take the risk.
