This has been a great discussion. I have been using the No-Toil filters, oil, grease, and cleaner powder with water for the last few years and haven't had to rebuild anything yet. The filters look like new after you clean them and the oil really catches the dirt. I feel the inside of the CMF airbox for grit after removing the filter and it is clean. Rosemary appreciates the fact I don't smell like gasoilne or kerosine after I clean them and I do it after every race weekend. Chicago Jerry doesn't like No Toil oil because if you let the filter sit for a long time (6 months or longer), the element can get stuck to the cage. Solution, clean your filter after every race weekend and don't oil it until you are ready to use the bike again.

Since day one when NO-TOIL came to the market,and after I testet the function of it in my Vintage and KTMs,I have never used anything else.
It is the best thing to dirtbiking ever done.
I can wash the filters in my wifes laundry top without getting shot.
I dont need rubbergloves and it is totally biodegradable.

The reason you do not use gas on a foam filter is for the same reason you do not leave gas in a fiberglas tank. It eats them... Lead is not the only thing that has changed in the fuels of today.... I have been using No Toil for the last four years and it has worked really well... but there is a problem... it is only to be used if you are planning to ride the bike... they tend to gum up and harden if they are left of the filter for a long time.... so if I am going to put a bike up, I will clean the filter and put it in dry.. then when I am ready to ride it again, I will clean the filter a fresh and oil it....

Andrew,
I don't think UNI makes a filter to fit the 78 filter cage. Al Buehner may sell the No-Toil. I will work on sending you pics comparing the stock 78 filter housing and cage and the updated Hi-Point replacement that I converted to the K & N filter today. Mike

.............never had a problem leaving gas in a fiberglass tank, even real live race gas [:0] is there anything else???  'Cause the rest pings in the can!.........

I always cleaned the old filter oil, mud and goo out of my filters with gas, and then used hot soapy (laundry detergent) water to clean and rinse the rest of the stuff out.  Then I leave them in the sun to dry before oiling, greasing and reinstalling.
  With todys KTM air boxes, these filters get so full of mud and water and crap so quick. I have a spare filter for all 4 of my vintage and modern race bikes.
 I also duct tape the air box up with matching black duct tape to help keep the polywogs and milfoil out [8D]
 I've washed my filters 30 times since early spring this way.
 BTW grease the airbox and filter seals too.
 I havent a clue on the part numbers Paul, I pay the  parts man to look it up for me

Hmmm... I remember since 80s. when I started using foam filters in all maintanance books was said "DON NOT USE GAS FOR air filter cleaning. That will destroy your filter!"

...........if that is the case as stated above then we are all in trouble, non reed valve engines produce good deal of spit back and you can bet it makes it to the air filter..........

I just got off the phone with the Twin Air folks,
http://www.twinairusa.com/contact/
 They said if you have a failure with their product to contact them as they stand behind their products.  The filters for the CMF airbox units is # 154200, as Gary stated.  The reason I asked for the part number is that the local dealers who handle Twin Air products have not been able to get that number from their systems, even the ordering system on the Twin Air site could not find that filter, but their customer help person was able to find it.
   
     If you need help with a Twin Air filter, call 1-800-749-2890 and ask for Jerry.  I asked him if I could post this information and he said to please DO post it as they want to help anyone with a Twin Air problem.  The new 154200 filters on their shelves are older, he said if I have any problem with the new product they are shipping that they will have new filters made at the factory.  They are replacing my filter at no charge and would like to have the old one shipped back to see why it failed.
   
     He asked if I had washed it in gas, I said I did, he said that was not good, I told him it said on their homepage that you could use gas.  I mentioned that if gas is bad for them that they need to take that info off their homepage, he said gas must be OK if the factory folks posted that on their homepage, I will be curious to see if that information is changed.  Below is their homepage filter info.  These folks treated me like I was their best customer, they are A-OK in my book.  Hope this helps.

TWIN AIR DUAL STAGE FILTERS
From everyday riding to the most adverse conditions nature can dish out, you want engine protection you can count on. The Twin Air line of air filtration products will provide your motorcycle with maximum intake protection... day in and day out.


 
  1. Coarse open-pore outer foam catches airborne dirt, grime and sand.
 
  2. Fine open-pore inner foam acts as a second filter to trap the smallest particles while ensuring maximum air passage.
 
  3. Exclusively formulated adhesive withstands repeated cleanings, even with harsh solvents or gasoline.
 
  4. Thick, flat foam, greaseless sealing ring ensures maximum contact with your airbox, while acting as a breathable gasket for increased air passage.
 
  5. Fused outer and inner elements prevent dirt and grime from being lodged between layers, unlike Twin Air, this can be a problem with inferior two piece designs. Trapped particles can restrict airflow. And if dirt works its way into your engine, a pinhead sized granule will gouge your cylinder, piston and rings like a bullet.

Paul,
  Excellent follow up.  Sounds like to me that they may have had old stock, but want to know any problems and will stand behind their products.  I have had good luck over the years with their product and use gas sometimes to clean their filters.  Having worked for a major company at one time I always tried to follow up on product quality and yes Honda has had some major problems believe it or not, but I feel most of the time (past tense) those problems were address.  Thanks again great post.

I always thought that "Twin Air" got their name from the dual stage air filters that they produce, but John Penton informed me otherwise.

A few years ago, Toni and I were talking to John at a GNCC, and we got on the subject of air filters. He told us the first time he ever saw a foam air filter was on a desert racer's bike, and the rider had made it himself. John said that he thought it was a great idea, so he called a friend of his to see if he could make some. His friend was Bob Twin.

...........Twin-Air is originally from Netherlands, sorry...........

[bentrims]

Paul,

I am sure you have used 3M weathersrip adhesive before. Buy a tube to refurbish the Twin Air to better than new condition. Next best thing to duct tape.

By the way, what does 3M stand for (trivia)?
