No air filter

[remo2k9]

took it out totally, sounds awesome goes awesome n faster ,   can someone list the cons? , for now all i noe is floatbowls need more cleaning very often , and ur cylinder will die faster or piston donno wat its called in english lol

Without a filter you will loose intake vacuum and with standard jets the mixture will lean off, uphots include: Hotter running leading to overheating and burnt plugs possibly even pre-ignition and burnt valves. You might see hesitation when on the gas, rough idle and difficult starting...Thats in addition to all the crap getting sucked into your carb/engine causing premature wear.

If it runs noticably better without a filter then it has an underlying problem, I would put the filter back in and start looking for it

Cons as Sledge rightly said.
Significant amount of grit gets sucked in and the oil/filter won't be able to remove all of this effectively without the air filter present

I've done it on my old ZXR for over a year but those engines are significanty tougher than these GS500 ones and frankly I wouldn't chance it on these.

Quoting from Suzuki service manual:

The surest way to accelerate engine wear is to use the engine without the element or to use a ruptured element.  Make sure that the air cleaner is in good condition at all times.  Life of the engine depends largely on this component!

why run no filter? just put on a K&N lunchbox, it flows far more than even no filter with the stock box and will keep out dirt, win-win. but you will need to rejet with any high flow setup, else you'll run dangerously lean and actually lose power.

Con:
It will destroy your engine

[simon79]

Or also a K&N drop-in replacement filter will do, used without restrictor.

Running without a filter is something I'd not recommend. I did it for a few weeks when I bought my GS and found out that the filter was amiss (used bike). Needless to say I had a new one fitted by the dealer straight away (and for free, obviously). Even though, the OEM air intake is under the seat below the tank - quite protected from stuff coming in.

If you want even MORE speed, stop wearing protective gear and helmet!  They only increase your aerodynamic drag.  Short pants and a pair of sandals are all you need.  And you can really skip the sandals.

when I race I make sure to only wear boxers, for less drag. no sunglasses even!

yeah i would run without it i dont know why all these companys waste the money on putting in this stupid air filter anyways......just think of all the money you will safe not having to replace your air filter.  Keep us posted as to how long your motor lasts before it needs a rebuild.

Ha!  Amateur!   I wear Speedo's.   And just to save weight, I wear two sizes smaller than normal! 

While we are saving weight and dropping unneccessary weight that Suzuki bloats its products with, let's save a couple more pounds and leave out a couple quarts of oil.  That'll leave more room for the accumulated grit from not having an air filter.

You gotta think like an engineer...

hmm r u being sarcastic ther? Lol or is that a seirous thing,

hmm well im going to readjust my fuel to air ratio , and sorry but is rejetting the definition of that? LOL i know the engine will die faster then normal but the only thing ive been taught is that the cylinder covers? that when the tiniest bit of sand goes in to ur carb it will make scratches inside, so all i need to do is replace that evry couple years right? jst wondering how much it would cost for the cylinder parts , and i thought cleaning the float bowl evry maximum of 3 months will keep it good. I will see how my engine goes without the filter  , atm im liking hte sound and i notice a much smooootherrrr sound and power gain in the low revs up until 7k, it osunds like i have turbo at 5-7k rpm LOL i really really really really need to adjust air to fuel ratio. can someone link me to a how to with how to noe if its lean n rich 

[romulux]

Enjoy your increased half horsepower which is probably mostly in your head while it lasts.

As your rings begin to ruin your cylinder walls with the extremely fine paste of dust and grit your air filter would have caught, your perceived performance gains will be lost as your compression decreases.

The sound might stay nice even as your engine power goes down, so I guess if sound is what you care about...

[romulux]

To get a rough idea of your richness/leanness, pull your spark plugs and look at the color of them.

Remo,

Read the thread, man. Removing the air filter will wreak havoc on your engine. It will ruin it. Stuff it up. Resulting in LESS power.

i got this idea from an experienced bikest / mechanic his from thailand, his had a kr 150 kawasaki that is able to go to 200ish km/h he never had an air filter / air box and made a pipe to go outside for more air for 10 years and ive asked him how many times did u change ur CYCLINDER , he says once u dont have to rebuild the whole engine it only jst wrecks ur cylinder or pistons as wat he said .. imagine... Thailand...t he roads... full of dust n shaZam! .... , im just wondering to all those people who have said that it will kill ure ngine n stuff , was it from past experience have u had no air filter b4? and did it wreck ur engine? really need to noe, if so im gnona put it right back on LOL

[the mole]

Guys, if he believes someone has a Kawa 150 that does 200km/h then just leave him to it. Save the wear on your keyboards.

[jeremy_nash]

I dont understand the reason to run with no filter?  are you THAT BROKE? if its just for the sound, then put on a lunchbox.  I have started the bike with no airfilter before, and sounds the same with my lunchbox installed.  in the long run, I would think a cylinder rebore, oversized piston, and new rings would cost more than a $40 high flow filter!

[remo2k9]

im jst seeing how it will go , jst wondering if anyone ever run it for years or how ever long till they had to change it  still thinking if i shud keep it out hmm , like all my cousins n my uncle says little more power but lower engine life lol wonder how long it wud last without it and with it thats all

lol u guys shud go thailand and check out the bikes there its pretty hektic  they parts for motorbikes are probably hmm...1/10 of watever it cost in US / australia lols my cousin has a fuckign scooter done up wit like aprillia breaks n fkn ohlins shock damper n all this f%$king other shaZam! lol like wat the uckfay man... im not surprised a kr150 can do 200 in thailand motorbikes very popular they do alot of shaZam! themselves wat my cousin told me was he umm donno if its right in english but sanded the cylinder wall to make it thinner so thers more oil combustion? or seomthing drilling holes in ur swing arm for weight reduction and ur FRAME? or chasis  lol they go to that extent for performance man like dam i wish i live in thailand fkn parts so expensive in australia they also street race for money and shaZam!  but watever ull only believe once uve seen it
