Air filters

[NR555]

We had unifilter custom make a few filters for our EMC CZ airbox.  It was cheap-as to get them made up and we've never had a problem with the filters. 

My filter cleaning method:

5L of turps from bunnings
2 buckets with lids from bunnings
1 round cake cooling stand from the supermarket
A metal clothes hanger
Rubber gloves

Put cake cooling stand in bottom of bucket 1.  Put about 3-4L of turps in there.
Hot soapy water (I find a cap of truckwash works fine) in bucket 2.

Put the dirty filter in bucket 1.  Slosh it around.  The cake stand will prevent the filter touching the bottom of the bucket where all the dirt is.  Squeeze all the excess turps out, but don't wring the filter.

Chuck it in the hot soapy water and work it through the filter.  Dispose of the soapy water on the lawn or something (it will be slightly tainted with turps).  Give the filter a quick rinse under a tap.

Cut the coat hanger on one side near the hook, bend the sharp end over.  Feed on all of your freshly cleaned filters (I can fit 4 on one hanger) and hang on washing line or in shed somewhere to drip dry.

Put the lid on the turps bucket and store.  I can get nearly a season out of the same turps, as long as you have something in there to stop the filter touching the bottom of the bucket.

niCE layout 555, good explaination, similar to what it do without the fancy cake stand :O)   but the Uni still peel out after 12 months, were yours a custom foam or the same old green shit as we are struggling with?

Rub it. does it peel or ball up ? what colour is it green wide or yellow close mesh?

freakshow, the grey ones are out of the unifilter catalogue road bike section they are universal road bike pods but in the special grey foam for road bikes. the offroad unifilters are red and green i put them on a 78 KZ650. different sizes are available and yes you could use  a outer sock over them. i would go fot their proper offroad pods though. download their catalgue off the australian unifilter website. all the info you willl ever need to know is all in there

Yeah you can use fuel and see no problems but there will be. the fuel opens up the pores of the foam more and lets larger particles through. just because it doesnt look damaged doesnt mean its not. your choice though

NR555 I'm surprised the turps dosen't stuff the plastic bucket as flameable products are stored in fluro plastic and I dout your buckets are made from fluro plastic.jimson

ill go down to see clint @ yamaha office, parrently they got the distrubution rights on the uni stuff in AU, ill but my nuts on the counter aqnd ask for a free bee, if not i wont leave till i got won i like the look of.

Been using socks on em too LWC, and they are just as balled up like they are rotted, you touch em and they just fall away in your hand. somthing weirds going on with the foam

I've only ever used Twin-air filter de-greaser in a Twin-air bucket (with the wire thing in the bottom like 555 is talking about), rinse in warm water with a bit of disho and then rinse in water. I only ever use Uni Filters and I've had some for years. As good as the day I bought them I reckon! 

[Freakshow]

lilke i said ill find out, i store them oiled in plastic bags, maybe that has an effect.  anyhowsss, will report i find somthing interesting.  maybe just a shit batch.

[LWC82PE]

the only problems with unifilters ive seen are after about 10 yrs they wear out and the glued seams come apart. i bought a nos PE one though and it just fell to bits in my hand .

when washing filters i use Chux multi purpose rubber gloves. they are the only gloves ive found from the supermarket that can handle fuel and turps.

Ok spoke to big kahuna at UNi filter, they sent 2 new filter and sleeves.   Word from god is never wash in water thats what kills them.  IF you cant get them crunchy dry moisture is retained in filter and when you oil it you trap the water in ther again and so on. he said they is no real need to wash out filters especially if you used petrol, turps or some other oil based products..  MAde lots of sence they way he explained it.   

Seeings as he was good enough to provide 2 new filter set $80 + for nicks im going to  do the right things and follow his cleaning program and see how long they last this way.

2 thumbs up to Uni filter for sticking behind there product when asked to

I'm a tight ares and make my own Filters and get at least 3 year plus out of em .  Use closed cell foam and Aeroflex compound

Yes, I have to agree with that, petrol gases expand and explode the foam bubbles were as turps doesnt. Luckily Im a painter and turps is readily avialable but the taste is shite, (I must stop getting on the turps)

Down side of the 754....... got to buy four filters, four spark plugs,four plug caps etc etc............. I use four of the gray road bike type, inside a  cutaway and converted  standard air box ., These have been excellent for some years as compared to the early green ones which last one season if lucky before breaking up.
