Last weekend I put a KnN filter on my bike as part of the 20k mile maintenance. The filter seemed to cause a huge flat spot between 3-4k RPM's and also a surging idle. This morning I swapped the factory filter back in and both problems went away. Just to make sure I switched back and the flat spot and surging idle came right back. So if anyone is interested in purchasing a slightly used (<50miles) negative performance air filter let me know.  | ||

if you give more air to the engine, the engine gets even more lean, K&N + new muffler + remapping is how it goes. | ||

3K to 4K is in the learning zone. I would put it back on and ride for a while and let it learn that it has more air. It should richen itself over time. Get it out and run it at a constant 3500 rpm for a few minutes and see if it doesn't change for you. I have a K&N on mine and it runs great. | ||

What improvement do you get with the K&N? | ||

Your wallet is $40 lighter, so it increases your top speed*. *Requres installation of the optional K&N Power sticker (Message edited by froggy on July 24, 2010) | ||

he he he froggy is right actually money burns in the pockets. | ||

That would mean less heat and you may not need a comfort kit then, that would mean more money in the pocket and more heat, that would mean you may still need the comfort kit.........now ya done it. PayPal me the hot money and I'll dispose of it at Erik Buell Racing and will not charge you shipping for it. | ||

K&Ns may allow more air through... but Im not convinced they are ANY better at filtering the fine stuff out of the air. Which, as I understand it, is the primary function of an AIR FILTER - thats why they call 'em that. | ||

I run re-usable filters for mainly that reason - they're REUSABLE. I hate buying stuff over and over again when I can get one that works equally well, and can be cleaned and re-used. And it's apples and oranges...but my turbocars always run better with K&N filters than with stock paper elements. That's another reason all my Buells have them. +1 on taking the bike out and letting it re-learn the AFV for the new filter. | ||

I agree with the 'throw away' downside of stock filters... But they are 'reusable'. Soak 'em in a bucket of warm water for 30 mins with some simple green, agitate a bit, then gently hose off with nozzle on 'shower' setting, pointed inside out. (high pressure will tear the fibers) Let 'em dry in the sun and... voila' - new filter. I only do this for one cycle - but extends life of otherwise expendable item. Early on, before 'oil level mystery' was solved, had enough oil in my airbox from unintentional overfill that it acted like an 'oil impregnated' filter. Simple green took care of that too. Now I gotta figure out how to clean oil filters with the stuff... | ||

I've got my original air filter and clean it once per season. Put liquid dish washing soap on the pleats and then back flush with warm water until clean. Hand in the shower over night to drip dry before reinstalling. I've discussed this on badweb in the past. I have no idea what a new stock filter costs but it looks like it might be a bit high. Why buy new when these rugged filters can be washed many many times. (Message edited by electraglider_1997 on July 26, 2010) | ||

Im with you Electra. They are tough & can take cleaning with no damage, if you're not too "ham fisted" with 'em. I paid about $25 (I think) for my 'spare' filter. Now I just alternate between the 2 and dont have to wait a day for drying, or to button Uly back up. | ||
