Well, 8 months after installing my V&H V02 Naked breather, I hear this rattling for a bit, turns out the thread component on the main air filter sheered off, so the stock cover, seemed as though it would fall off, but in fact, it was still tightly bolted, but was rattling be cause the thread was no longer attached to the main filter housing. I assume that it's possible I tightened the cover too much and over time, the vibration caused it to break. Well V&H only warranties for 90 days. So no I have to choose to replace it with something else, between Kuryaken and K&N, anything new seems to run about $250 and up. not sure if I'm ready to pay that, other than bolting the cover back on and living for the rattle for a bit, I suspect I don't have many choices, I don't think I want to ride without the cover, as foreign objects and dirt can get through the hole in the middle where the threading is.
