Air filter maintance? BS, it should be titled "How to take a brand new air filter out of a bag and install it on a new bike". Real maintenance would be removing and cleaning a filter on a bike that just ran a dusty or muddy moto or a long trail ride.

You never wring an air filter like that. You squeeze the oil from inside out, but not wring it. Maybe if you get a new one after a couple of washes you would.

I've been doing it wrong for 30+ years.

I have always greased the seal.... and I don't oil the filter skin.
I don't wring the filter out as he did.
Never too old to learn I suppose.
Actually, I prefer my way.

Ditto on wringing the filter. I also let the filter air out for 15 minutes or so before installing. Modern fourstokes will suck the oil through the motor otherwise. Not one of Racer X's better maintenance tips.

he's got it all wrong wrote: 8:42am July 22, 2011

After cleaning thousands of filters after 30 years of racing moto, there is so many things wrong with that video. Start with a water based oil like No-Toil and make your life easier. I have never seen so much oil put on and from the inside? Toss the filter condom too...and just clean it after every ride. Couldn't believe the way he cleaned the airbox out either. I have a twin air waterproof cover so you can hose it out,,but even without that i wouldn't just spray straight in the airbox. Could go way in the boot. Clueless. 30 years and never sucked dirt or grenaded a motor so i must be doing something right.

Sorry guys..but wringing out something is when you twist it...he was doing a super aggressive squeeze...lol

He actually told us to "wring" out the filter. I guess when you get to the top and your stuff is free, you can be careless with it. I would NEVER follow any of this guys methods. What about putting your oil in the bucket and submersing the filter in it and then squeezing it out, he was very messy. Dido on the No Toil...absolutely the best thing to happen to air filters. I love the stuff, would never go back to the petroleum stuff again.

@Im my own mechanic.... You say "when you get to the top"? This guy isnt at the top. I see him hanging banners at the local tracks here in Southern California, not what top level guys do. Agreed his methods didnt seem like mine over the last 35 years of maintaining my bikes but please dont confuse him with someone of importance in the industry. Now if Goose was doing a segment on anything maintenance related we'd all just say thats how you do it, no matter what it was.

That was the worst example of filter maintenace you could ever see! Please erase this from your memory!!!! Most of you above that seem to know are pretter much correct, Yes e's got it all wrong and I myself cringed when I saw him wring the filter GEEEZ dont let this guy touch your bike!! Woder how he whases the filter?? no I dont wanna know. , Yess I have cleaned and taught many people how to clean them. as follows........

Firs either be single or have the wife or girlfrind out of the house. I used to race 2 or thee classes a day on the same bike unless it was not dusty at all I changed filters if I had time between every moto. Now first make a coffe can or somthing shaped to fit your air filter seat for a cover. use that as soon as you take out the fillter.should stay in place with the grease that you should have therre. Then then lightly work the major crud off in a pan of kerosine,or disel fuel it will break down the filter oil and grease then put in sun or ventalated area to dry Now when female is out of the house go to the clean kitchen sink and make hot water with DAWN dishwashing liquid wahsh all filters several times till there is no more dirt then rinse very weelll in the other side of the sink to make sure filter is clean, Next step is to throw all of the filters in the dryer at very low heat and let them tumble dry. Then take all filters out and run sented static cloth in the dryer with an old towel. That will keep the woman happy. be sure to clean kitchen very well also!
Now we are ready ro properly oil the filters DO NOT WRING filters this will tear the foam.Pour liberal amounts of filter oil on each filter only squezzing out ass much oil with your hands then uses paper towels to get more of the filter oil out. then leave out on the workbench overnight for the achohol base to evaporate and you will have a very good clean filter. I then put eat filter in a ziploc bag and they are ready to go!!
Proper air filter maintainence is the one most impoertand factor of your engine! Do not let that dodo touch your bike. I do this with my lawn stuff and all foam filters

You are welcome any comments other than my typose??????

For awhile now, I've use two Uni filters and rotate them so I have a clean one for every trip out. I use the Uni or sikoline oil and liquid dirt remover for the cleaner.

A few of my buddies use Swaff from RokOil that can be rinsed in the sink and it makes the chore very easy. I’m not a fan of it in the rainy season for obvious reasons, but it seems like a great choice for the summer. It sure is faster than my method.

I agree with the general consensus, this is a terrible instructional video. The wringing? His oiling technique? And it's cheating starting with a new filter. Like most of you, I've been cleaning & changing filters for 20+ years. I recently tired of the solvent fumes and switched to No-Toil, which has made filter cleaning SO much nicer. It's amazing, takes all the hassle out of the job.

This is my first time commenting on your site but I felt I had to. This is the number one maintenance item on a bike and this example was horrible. Not a good example at all. Turn this into a good thing offer a subscription or some swag for the person that puts up the best filter maintenance video. Let your readers vote.

Thanks and keep trying

Nice guy, but never wring your filter, only squeeze it repeatedly to distribute the oil. I had a problem with a filter a long time ago, and it turned out that the filter foam was worn out! Squeezing will prolong filter foam life and maintain the small size of the open cells, maintaining proper filtering. Wringing the foam tears the cell walls, making for more open cell paths through the filter for dirt to pass. Be warned! You'll pay the price in rings, pistons, bores...

My top ends always look amazingly fresh and my rings wear sooo slowly. I clean my filter like it's an aircraft after each ride.

Some of you will scream bloody murder, but I clean my filter in gas to cut the grease and oil. If I'm not in a major hurry, I'll clean it again with dish soap in the sink and let it air dry. I don't use expensive filter oil and have NEVER had a problem using ordinary motor oil on my filter, squeezing it out and then applying lithium grease to the lip. I like lithium because it's light, easy to clean up and visible but sometimes I use regular axle grease. Motor oil and a greased lip stop everything. Depending on the design of the filter, I might also grease the foam around the filter bolt.

Another thing I noticed in that video is that I could hear the grit on the countertop after he cleaned the filter frame and slid it across the gritty counter. That picked up some nice sandpaper granules to work on the carb and top end.

Then, after he oiled the filter, put the frame inside it and put it on that paper towel, the lip of the oiled filter went off the edge of the paper towel and blotted up about five inches of grit off of the countertop. It wouldn't be hard for that grit to get into the engine from there. That made me cringe.

haha... wtf. I clean my filters in gas and wring them out gently, and wash them with detergent after that, let them fully dry (assisted by fan usually), and I spray them down with PJ1 Filter Oil Spray (a lot less wastefull and messy than this method). When done properly, your filter should look brand new after every cleaning. Also, I regrease the mating surface of the bottom of the filter to the airbox, I feel like that's something important everyone should be doing.



At the old shop where I worked at I would wonder how so much filter oil could be sitting at the bottom of an airbox and this example is why!!



Have fun cleaning that sh*t off your bench dude.

I work for No-Toil and if you want to properly oil a filter, this is how and why we do it this way. This will work for any filter oil being used.

To oil your filter I always pour the oil on the inside and then massage and squeeze to get complete coverage on the filter. Doing it this way makes sure that you have oil on all the cells of the filter. If you cut a filter in half the dirt actually can make it a long way into the foam, so you want to make sure that your filter is completely covered in oil. You want to be able to squeeze out some excess oil, that way you know that your filter is oiled properly. I recommend leaving your filter out overnight to let the carrier evaporate completely out so you know that all you have left on your filter is the oil.

Filter cleaning is another beast with more methods to how to do it then I have fingers, toes and teeth, so lets leave that for another time.

HAHA JV212 he cant even get it in the bucket. LOL WOW!! total new school squid. I laughed at the stupidity of this guy. Please kids and new riders that is not the best way to install a filter. The guy could have blasted grit right in the boot with out even knowing he was spraying so hard in there. I could go on but I'm to disgusted.

Most of the Methods in this video are good.Cleaning the air box is always good.But spray the contact cleaner on a towel first ,then wipe the dirt away.Only spray as a final cleaning.People are still using grease?PC Racing makes a filter gasket that costs less than $15.Made of neoprene,It is impervious to cleaners.and lasts a long time.I put one on every one of my bikes.I use only as much oil as the filer will take,add a little at a time.Don't wring the filter into a bucket.Jay has his reasons for the way he does things,Don't you?

NEVER wring a filter you can tear/streach it out and never blow contact cleaner into the boot or you can blow that dirt he was talking about into the carb/throttle body. Grease is a good idea not totally necessary but good. To each his own
