ADVBedoulin, I used a standard Remus Hexacone titanium for a 1200GS. I just shortened the can by about 120mm ( 6inch )

ADVBedoulin, the red sponse that you see on the air-intake of Jacko's bike is part of the Uni-air filter's pre filter. You can not buy the prefilter seperately, it only comes with the unifilter kit. The best filter on the marker if you ask me. In this picture the prefilter is black but is is available in many colours

While I believe these filters are good for very dusty and sandy conditions they are retrictive for general use. If you look at the available surface area of the fliter and then how the two circle cutouts restrict this by probably at least 1/3 you will see what I am getting at - couple this with a potentially overoiled and restrcitive sponge and you have an asthmatic HP2!!! I personally use a well serviced K&N in preference.

You couldn't be further from the truth although it's easy to understand why you have your theory.

We've tested the filter only pictured above on a flow bench against an OEM paper filter and K&N filter, the foam filter beat the K&N by over 50cfm because of it's design.

Now if you add the pre-filter to the equation, the all foam set-up still flows comparably to the OEM paper filter but is only a few less CFM flow. Take out the pre-filter and it's the highest CFM filter and the ONLY filter to have installed if you try to suck in water.

You couldn't give me a K&N to run on ANY of my bikes, specially if I was in a harsher/dustier environment like SA or Australia outback.

K&N and similar filters are engine killers, especially if you ride in dusty terrain.

The Unifilter is the best solution for an HP2. At least, that's according to the experts.

With the prefilter off, the bike goes like stink. It's only really a cable tie that you cut. But it is so valuable i.t.o. clean air that unless I'm only doing blacktop, it stays on.

Good info re filters.

Where do you get the Unifilter?

The Touratech website has a foam filter that looks identical to what Losper posted, listed at $103.

Meanwhile Unifilter.com lists their R1200GS foam filter at $33 (part number NU-7307), but they don't have a picture. That's a hell of a bargain -- enough of a bargain to make me suspicious that it's not what I'm looking for....

Can someone confirm the Unifilter.com part is correct?

Thanks.

You're looking for the Unifilter Australian version vs the USA Unifilter. Yours truly stocks the Australian version with two pre-filter air socks for $60ish which is produced by the exact same folks of the Touratech kit.

Cool, thanks. I'll give your parts desk a call tomorrow.

I've got some Motorex "Twin Air Bio" oil. Sound reasonable, or do you recommend anything special with these?

they come pre-oiled and from there use what works for you, there's no adhesive glue holding it together, so most of the bio-degradeable filter sprays will be just fine.

Sounds like maybe I must rest my case but still do not logically understand how if you reduce the filtering surface face area you are going to get better airflow??? Yes they have increased actual filtering area internally withe thr tubes but unless there is some venturi effect how does more air get through??? As I say I service my K&N very regularly and have run a pre-filter with it. But maybe must try thre Uni too.

When you buy the uni filter ( with prefilter ) it comes pre oilled ( the airfilter and the prefilter ). It is important to clean and remove the oil from the pre-filter. This means that only the actual air filter must be oiled. If the pre-filter is oiled as well it becomes to restrictive and not enough airflow passes thru. This combination works extremely well. The aifilter ( oiled ) acts as a filter for small dust particles and the pre-filter ( not oiled ) act as a filter for bigger pieces like leaves, bugs, flies etc.
I did a lot of riding in desert sand about 3 weeks ago. When I got back home I took out the filter and had a look. On the inside of the air filter ( oiled ) there was about a 10mm thick layer of sand and on the inside of the airbox there was zero dust. It was completely clean. This means that the Unifilter did exactly what it was suppose to do, keep the engine clean from dust.
BTW, I actually own 2 HP2's. The one has the unifilter with prefilter sistem and the other bike has a K&N filter ( also with uni-prefilter ) attached. The bike with the complete unifilter sistem performs better.
