I took my '06 600rr to the Honda service center with an K&N on my back and told them to put it on for me, they said that all K&N filters they've seen on bikes shown visible signs of leaking dust from the edges into the valves as it never seals properly, and said there's no way to fix this. I told them to put it in anyways and thought to come here and invistigate! I'd appreciate if anyone could offer some more input.
Thanks.

 

dealers only like the stuff they sell..period

if they dont work good...why do so many ppl like them?

 

lame service people... K&N, the definitive name in aftrmarket air filters. A slurp of grease, on the sealing surfaces... used on a bazillion dirt bikes, and my K&N fitted CBR. Find service people, that live in the real world.
Clean and free, Ripp'n

 

cuz k&n is not any bettr than ur stock filter!

 

In general, with both filters clean the the K&N does NOT flow any more air than the stock filter, but when both are dirty the K&N will flow more air.

With that said you have to realize that the stock filter, even when dirty, is still capable of flowing more air than a stock engine can take in. I have also see first hand that the K&N's have a fit problem on the 600rr's and don't seal like they should.

If your after a quality aftermarket filter thats washable & reusable, BMC make by far the best quality one. Personally on my race bike I run the stock filter W/ the screen removed......

 

get a bmc air filter that'll treat ya right.

 

Like it was said before, the only reason why they said that about the k&n filter is because 1 they dont sell them at that dealer ship and or 2 they wanted you to buy from them! If you do your BASIC MAINTANCE you will be fine no matter what filter you use!
