K&N Filters.

Any thoughts on the above air filters, worth it? Make a difference? w;;v

cheaper in the long run, can make a difference depending on your "set up" :dunno:

I've used them in the past but didn't really notice any appreciable difference. About the only thing they save is relacement cost of the OEM filter, just wash 'em and refit instead of replace.

A lot of people in the know reckon they don't filter the dust as well as the paper filters and that you can see small pinholes in the foam if held up to the light.
:dunno:

To be honest I think I'll just stick with the OEM filter until someone I can trust can convince me they are definitely safe to use. We often have quite dusty conditions here in Australia so filters are extremely important to the longevity of the engine.

I fitted a K&N to my previous VFR 800 and it definitely made a difference. It would rev up a lot more freely.

I have now fitted a K&N to the bird expecting similar results, not so. I can`t feel any improvement at all.

I fitted one last year and its better on fuel, quite noticable too on mine.
Its not a great deal dearer than an OE one and K&N is for life, easy to whip it out earlier then normal and give it a clean.

I fitted one to my injected bird, get better mpg and it seems to rev quicker. If you fit one to a carbed one it will need re jetting though.

Looking at it logically, if an engine spins up quicker then you have say that the airflow through the filter is less restricted. But quicker passage through the filter doesn't necessarily mean better. It's only better if it still captures the same size particles of dust that the oem filter does.

Perhaps the K&N filter does - I dont know. Big up to them of it does, but it does sound like there is a risk of a trade-off at play with less restricted airflow. :dunno:

Got a K&N in the bird, had one in the mille too. It does make a difference, more so on the Mille. The low end grunt was more noticible than before. The bird just appears to have easier breathing. As for the dust trapment, I would trust a guy whose been fitting K&N filters to cars and bikes for the last 35 years, he swears by them and has never had ANY problems relating to the air filters. K&N also give a 1,000,000mile warrenty on thier products. Does Honda do that for THEIR filters?

[Wolfie]

chuff,i would get them rejetted and a k&n. wouldnot run race exhausts and a K&N with rejetting, then again i would not run the exhausts without rejetting.

 

[chuffmeister]

:h:dunno:

cans seems to have made the bike run better without re jetting , flat spot seems to have dis appeared but i do run with 2 out of the 4 baffles in

:dunno::h

 

[Wolfie]

personnel preference chuff.

i dont see the point of sticking a set of cans on and then not have the bike set up, I see it as having an ohlins shock and leaving it on the standard settings.

Worked hard for the cash might as well have them set up right as well is how i look at it.

 

[chuffmeister]

ah, i just stuck em on cos i cud................

maybe when funds improve :bang:

They flow more air... but it's a waste unless the rest of your gas flow system is up to it. No point in blowing a fan down a straw if you know what I mean. Since they flow more air, they must by definition be less effective at filtering out grit.

Want a professional opinion? Go to www.powercommander.com and click on the links for the blackbird's PC3. Have a look at the maps available. You'll see that the ones that mention after market filters say "OEM or aftermarket filter" Click on FAQ and you will read that they say this when the non OEM makes stuff al difference. Conclusion? It's only gonna save you cash in replacement filters....
