I hope you have better luck with this filter than I did. I bought one of these for my CRF and it was such an ill fitting piece of junk I threw it away after one ride, I also tried a No-Toil and it wasn't much better. I've got UNI's in all my bikes now and they work great.I:I
On the blasters one k&n with outer wears stock air box,,,black one uni.shee k@n stock air box with lid/ about to change though as soon as mail comes tomorrow.
