i dont know about you guys but iv not seen this before.....take a close look at the filter it is sucked in,when i noticed it i thought could the intake have that much vacum.......could the ports be pulling on the filter that hard.....it seems so...i did redesign-or-reshape the intake ports...whatever you want to call it

i started the bike and rev'ed it and if you rev it really hard you can see it pulling in the filter...kinda like a twisting pull

i dont know what to make of this one

your head pipe makes me feel better, mine is turning dark too
(It seems to get hot faster lately also)

sorry, I have no idea why your filter would implode like that

well this one turned like tha after only a few minutes,but it was also to lean...i went from a 160 main to 188

and moved the needle from 3rd to 4th

so if it was jetted right it may not have turned color

i cant see that it sucking real hard can be a bad thing, because that seems to look like it would make it faster, on the hondas the stock filter has a cage in the center, see if that will fit on the K&N and i wouldnt recommend sticking a foam filter on there, because i can see that sucking in parts of the foam into the motor = Not good
