i priced a genuine Z1000 air filter today while buying on oil filter.

and for half the price of it, i can get a DNA foam re-usable filter.

good idea? or bad idea?

i have foam filter oil, already.

what would i clean it with? i clean my RC cars one with de greaser, then wrinse thouroughly. let dry and re-oil.

would the same be ok for a propper foam filter??

yes, it might be best if you filter your DNA, dont want lots of little dudes backing it into turn 9 :wink:

oh you mean air filters.....wouldnt know :lol:

Don't know about DNA filters mate, but on the dirt bikes we always cleaned the foam filters with two buckets of kero. First one for cleaning and the second to make sure you get all the crappy bits out. Kero doesn't stuff up the foam like most other solvents.

For half the price I'd give it a go, although it'll probably then stuff up your fuelling and you'll need a PC3, so unless you really want a PC3 it might not be a good option

TKA use DNA filters...

by **Wattie** » Thu Apr 26, 2007 6:04 pm

hmmm, i can see it now...

"hey sweetie, you know that filter i bought for my bike> well its made it run all funny... so i'll just whack this little gadget under the seat, it will fix it all up...."

yer right... hahaha

i think i'll give it a burl, it it stuffs up, i'll stick a standard one back it.

i've got 30000k out of the original one, so i think im kind of ahead already :lol:

Buy the DNA

Wattie, they let the bike breathe better...

Me biased? no never..

yes we do sell them

by **Neka79** » Thu Apr 26, 2007 6:39 pm

mate superbike supply do a DNA + PC3 package for abt $500 ish...actually i think its $460 or sumthin??

im currently saving for one....

also its not uncommon for the aftermarket units to make the thing breathe better and stuff ur fuelling (my fireblade dropped 3hp with a K&N on the dyno) ... so yea..get both...

DNA filters are very fucken good... had one on my 636, breathed easy as, for a shade over the price of a standard kawi filter (was lucky, and looked after very well) equal to k+N filters in quality apparently. do it... my 2c -J.

I run a DNA on my racebike.

Hawk Kawasaki use them as well as TKA.

Much better than K&N and BMC in my opinion.

I had a mate that threw is motocross foam filters in the washing machine - not sure it did them or the machine any good though.

If you have a race can, putting a filter on will def weaken the fuel mix (breaths easy on both sides of the motor). It'll be off to the dyno to turn the PCIII - Seems cheaper just to get a standard one, unless you're really running out of power on the Z1000

I've heard good things about the DNA filters. As far as the fuelling goes, I've got a K&N and the Akra and my fuelling is fine on the dyno.

Modern standard filters flow just as much air as the aftermarkets these days, but can't be cleaned, so you have to fork over your hard earned everytime they get gunked up.

Aftermarket filters like the DNA, K&N etc simply have the advantage of being able to be cleaned and reused.

The best flowing filter is none at all, so don't forget that the reason you have a filter is for filtration. No point in choosing and buying a filter without knowing jack about how it filters.

by **deafwish** » Fri Apr 27, 2007 6:37 pm

I'm going to say the opposite to everyone here......

Don't buy foam filters on a fuel injected bike, as the foam filters have larger 'cells' (that trap the oil that filters the air!) than a surgical cotton type filter.
I know from experience that with performance cars that have an air flow meter or temperature sensor close to a foam filter, the oil very often gets pulled/ sprayed on the sensitive sensor and can often give faulty readings. This could potentially lean your engine out enough to do damage.
Yes it can happen, yes it has happened.
If you have to get an aftermarket one, stick with a tight knit surgical cotton filter and never over oil it.

p.s. Foam filters work fine for carburetted bikes.

Just my 2 cents mate.

by **Wattie** » Fri Apr 27, 2007 6:59 pm

just a quick question< does the Z1000 fuel injection have an oxygen sensor???

anyone got hard evidence??

by **ttc** » Fri Apr 27, 2007 7:34 pm

don't think so but could be wrong

I've had an aftermarket filter on the zed for 14,000km and I had one on my zx6 for 20,000km

With the aftermarket filter and having the pc fitted, 4 more ponies at the wheel of the zed
