Air Filter Maintenance How to clean your air filter and why you should

Thanks for the info.  One of the reasons I asked is because I also noticed the inside air filter was always very clean so I have only been cleaning and applying oil to the outer filter.

Thanks again

Great thread, DLHamblin.  Followed this and had no problems cleaning and oiling my filter for the first time.  

Great post Dave!! i enjoy reading maintenance threads. pretty in depth but regular maintenace is a MUST as you stress in this post...unproper inspection of all components can end up in fatal engine failures. so...yes properly cleaning oiling & reinstalling your air filter is very important..i use Uni- air filter cleaner & oil...im sure they all work just as good if u properly do it....but thanks for the thread.

I just wanted to add one little thing. I mix up a batch of No-Toil filter cleaner in a old Costco laundry detergent bucket. I only have one bike so I can use the same cleaner a couple times over a month and just close the lid between cleanings. But of coarse if it starts to get real dirty then I change it out. I just make sure I do a through rinse. And I dry my filters with the filter cage installed to help hold the shape and then I have a clean dry filter for the next weekend.
And I love the spray on No-Toil filter oil.  

i just took my filter out of my yz85 and its drying right now but it didnt seem like much dirt and oil came off. but whenever i try starting my engine it sounds flooded and like it cant breath. i bought it used just this sunday so i am wonder if it is neglected?

Start a new thread on the issue (it doesn't sound like an air filter issue).  You will get better answers that way.

Are the K&N filter recharge kits ok to use?  

I have a couple questions. First, The person that had my bike before I did didn't use No Toil oil.  How do I clean the filter so I can put my No Toil oil on it?  

Also, when you are putting oil on a filter, can you re-use the oil that comes out of the filter?

Thanks!

at a bike shop they should have an air filter cleaner, just ask them and they should help you out, it doesn't matter if the guy before you didn't use no toil, I constantly switch from K&N aerosol, to Honda oil in a bottle, and PJ1 aerosol, usually whatever I can grab first, when you pick up a cleaner just follow Daves instructions. And no you never re-use any old oil for anything, ever.

Just use gas or whatever to clean the old oil out, than rinse thoroughly. If you catch the excess in a clean bowl or bag, sure you can use it.

I just work small amounts of oil into the filter until it's saturated, so I dont have to deal with a puddle of oil.
