Question klr air cleaners

I installed a K&N air cleaner on a 2010 650...great performance, but it was totally clogged in 200 miles of dirt riding...the bike would barely run. Does anybody have any other suggestions for an after market air cleaner that will enhance performance, but not get clogged so quickly.

I use the Uni air filter. It seems to be a good one. I've heard the stock air filter is better than the K&N.

If you're doing a bunch of dirt riding, I'd look into Filter Skins. They have a cord that you can pull to remove the dust laden cover to get clean filter afterwards..

And I also agree.. K and N filters are fine for street riding, but I won't condsider one for dirt riding.. I'm also a Uni filter fan!

Hi t s love. Welcome to the forum.

Our engines are basically air pumps. They draw in through the intake, and spit out the spent stuff out the exhaust. The only thing keeping the engine from drawing in bugs, small birds, dirt and dust, is the air filter. Any air filter that prohibits all that stuff from going into the engine is doing it's job, right? I think that if you read up on air filter use and maintenance in the dirt bike world, most riders will replace an air filter as often as needed in a dirty environment. Most carry a filter or two in a zip lock bag. You might consider something like that if you ride a lot in that dirty of an environment.

There have been reports of the K & N filter not sealing the intake properly on the KLR 650, allowing dirt into the engine. This is hearsay. I have no hands-on experience with the K & N on a KLR. The UNI filter gets high marks and praises. So does the stock air filter.

The benefits of an aftermarket air filter for this bike seems too minimal to me to risk any potential damage from a poor seal, or from a filter that doesn't do what it's supposed to do... keep the dirt out.

UNI all the way! I carry the stock one in a zip-lock for field replacements.

The late great KLRCary (Cary Aspy RIP) did tests with the K&N filter and found that it has less flow than the stock filter. That sucks considering it costs so much. I have used them in other applications and loved them Also the foam filters pack down better IMO.

A foam filter is far easier to clean on the trail than a K&N as well. I have three stockers, two donated by friends that had to have K&N's.

I need to clean my stock filter but I am out of the K&N filter cleaner stuff that I was using. Is there something around the house that I could use to clean the air filter?? Windex, shampoo, baby wipes??



For what its worth, I run a UNI and am keeping the stocker as a backup

Any air filter cleaner should remove the K&N oil. I used Uni filter cleaning spray once when K&N cleaning solution was out of stock all over town. It worked fine.

Oh and I only use Uni or stock filters. Tried a off brand once and the first time I washed it all the glued pieces simply dissolved and came apart. :-(

Simple Green would probably do a decent job of cleaning the foam.
