K&N filter, no good

i went out and bought a K&N air filter for my 2000 r6 and after wrestling with it to get it to fit right it made the bike run a hell of a lot slower and under full throttle the power would come and go as if the clutch was slipping. so i put my original filter back on and it runs great again. hoping the place i got it fro will let me exchange for a new stock one. has anyone ever experience this

How long did you let it run with it in? And what altitude are you at? Some of these factors will influence the way it runs..The onboard computer should fix the air fuel mixture. High altitude is thin air and your K&N is high flo..A few things to ponder.

K&N's are much more permeable than a stock air filter. As soon as I put mine in I noticed the difference, I could actually hear the air being pushed through the airbox. I love mine, but then again my bike is EFI. I recommend them to everyone, you probably do need to rejet.

u think it would be that evident? to the point where the bike would fall on its face at full throttle, and then once the oem filter is back in all the power comes back?

A K&n restricts airflow in most bikes, BMC race filter is proven to be the best to let air flow. So pretty much you are better off keeping your stock air filter, or go BMC.

I think he needs a rejet or shimming of the needles.. I seriously doubt K&N is worse then stock..

do you have a k&n in it now, or have something to go by with the stock?

Ok First off I have had people tell me the same thing, that K&N suck in a bike and don't work well at all. I have also heard that BMC is the only air filter to go with.
I have a K&N only because I got it for a birthday present with a stage 1 Dynojet jet kit (thanks dad!) I know that there is no way that a stock paper filter flows air better than a K&N!! Hard fact to swallow but hold them both up to light you can see more light through the K&N. My opinion this means that it has to also let more air through!

If you just drop in a K&N and run your bike it won't run as well as the stock because it's not tuned for it you are now getting more air and the same amout of fuel. Air/Fuel mixture is critical to the way our high strung bikes run. Any time you change the amount of air your bike can take in you need to change the fuel in the same proportion.

So in my experience with any engine, more air is good if you add more fuel!

Ok Flame away!

My bike has too much fuel. Needs more air.
