Recommend a replacement air filter XTZ
 

So here goes, Kev 02 and fuel mod fitted. Akrapovic exhaust, snorkel removed, so which filter should I buy to replace Yamaha filter?
Any advice welcome, experiences with K&N, Pypercross, BMC or others?
Regards Dave

DNA gets a good wrap up, got a foamy myself but just ordered a DNA to compare the difference.

Very satisfied with Pipercross so far: Not such a big fan of cotton filters (K&N, DNA) because they could let small dust particles pass through. Examples are easy to find here in the forum and on Google...
For road use it should not be a problem, but if you also take on dusty conditions, foam is the right material in my opinion.

Nevertheless, also take the time to take off both side covers of your airbox and seal them off with grease!

Hello,

Did we come to a consensus on which air filter? Is it worth updating or just stick to the standard one?

I'm changing my exhaust, riding predominantly road (coastal) but will do a small amount of off-roading (predominantly mud/gravel). No other mods to the fuel/air system yet.

Best place to buy from?

Thanks all,
Penfold

Went with a BMC filter in the end, cotton I believe, wound the fuel mod up to 5 o clock position, made a big difference!
Regards Dave

So True...
K&N / DNA filters are great... If yer don't go any where there could be dust....

Take a note where the K&N filter came in every test ===> http://www.dieselbombers.com/chevrol...r-testing.html

PS.... I use a OTR form filter... Had a pipercross but the OTR filter has a lot
more surface area..

Hi,

Doing a quick search on that well known search engine I found this http://www.ebay.co.uk/itm/Pipercross...item51bf3b9ee5

Is this the pipercross filter you're talking about? Did you declare the filter change to your insurance company?

Thanks,
Penfold

Got me thinking now that i should change my DNA for a foam filter, i do a lot of
off roading in dusty conditions.

For me, Dirt = foam filters, for the road = DNA, the DNA flter have the flow advantages over K&N, this does not mean less filtering of the elements, the XT660 DNA filters run larger pleats than the K&N filters giving a larger filtered surface area.

What's the flow rate like on the OTR foam filters


Time spent without rod in hand is time forever wasted.

Yes, how does the airflow compare between DNA and a foam filter?

The DNA will flow more air.

There's no black magic with air filters really, it's pretty simple: filtration is inversely proprtional to air flow. The more flow, the less effective the filtration and vice-versa. Filtration versus air flow is just one big compromise, you can't have the best of both. A bit like tyres really, you either have the on-road or off-road dedicated, and then there are the all the compromises in between, neither great at one or the other. You can't have your cake and eat it.

I'm with everyone else: Cotton gauze for road use and infrequent off-road work (in low dust conditions) to gain maximum flow and for lots of off-road work and dusty conditions use foam.

+1. No doubt about it, in my experience foam is the go for dirt work.

Thanks, iv'e just ordered a Pipercross

The glue on my Pipercross filter dissolved when cleaned with petrol....so into the bin after a few glue attempts.

I ordered an OTR one after which can be rinsed with petrol. I need a petrol friendly one as I clean mine en route when in Morocco.

Just a point to consider

OTR and air box lid
 

I've just bought the OTR filter. I'm running it with the stock airbox lid and snorkel. But when my Kev mods arrive I plan to open things up more. The OTR info says you can use their filter with the snorkel removed. Does this work ok and still provide a good seal, or is it better to buy a DNA Stage 2 airbox lid? I don't mind spending the cash if it provides a better solution and the opportunity to return the bike to stock, but equally happy not to buy one if there is no need.

I can't work out if you remove the snorkel if you can refit it again in the future?

I have my snorkel cut and pared off and it fits just fine.....I didn't feel the need to buy anything else to be honest.

:)

Works fine with the snork off , and the Kev mod is a must :smilies0349:

When you say with the snorkel off do you mean removing the snorkel from the metal part that screws down or does the otr foam filter come with it's own lid to screw it down to seal?


Time spent without rod in hand is time forever wasted.

Where the snorkel comes out of the top of the filter cut it off and then pare the rest off until you're close to the circumference. The OTR filter is shaped like a top hat as it were. The 'hat' is put into the air box and the rim is then squeezed down upon by the snorkel housing when it is screwed on again.

:)


.

If u remove the snorkel completely from its housing with the 4 screws in it without cutting it can you use the housing to seal it or does it need the rubber to seal it


Time spent without rod in hand is time forever wasted.

Filters
 

As the DNA Stage 3 filter is a lot more exposed than the normal filter does it still work OK if its chucking it down.

I believe its made of cotton ?

Will it degrade and fall to bits if exposed to heavy prolonged rain?
