The race version probably has a slightly different filter media, allowing more airflow (and more dirt) through it. I have a BMC street filter on my 1000RR.
Hey One2,I hate how the foam deteriorates from around the BMC filter. I sold mine and bought a K&N street filter.
Might even switch back to stock since that's what AMA uses. :corn
Yea the more dirt part is the concert. But may many people use them, so makes me want to use one too for better breathing engine :cool008:... allowing more airflow (and more dirt) through it. ....
Hey YZF-Rich, are GYTR made same way as BMC ?My guess would be the thickness of the filter itself. The GYTR filter I have is a lot thinner overall than the stock filter.
GYTR on the left, Stock on the right...
Not the filter itself but the foam that surrounds it. The foam that insulates the groove it sits inside of in the airbox.Hey One2,
What do you mean foam deteriorates, which place on filter? Just trying to understand where this is, and if it opens up major holes.
I would go for 'standard' (street?) BMC. My only issue with them so far was (on another bike) you really need to watch them and oil often, else all gunk / dust or micro shit gets through. I opened one airbox after a year not checking and.. that was the most mess i ever seen in the air box, and totally dry BMC filter.
So you saying, AMA just uses the stock oiled paper filters?
I don't know. Never had a BMC before. My R1 had the original air filter on it when I got it about a year and half ago.Hey YZF-Rich, are GYTR made same way as BMC ?
Hey Sabotage,I use silicone to make sure the rubber around the race bmc filter does not allow any gaps for air to sneak through. My dyno tuner told me to buy the race, from his experience he gets better dyno results so thsts what I went with. I was worried about the filtration also so when I first got it, I inspected the throttle bodies and filtered side of the air box to see if dirt was getting through. The inspection never showed signs that dirt was getting through so I eventually stopped worrying about it.
