Just ordered a pair of 60mm air pods for my GS.. what i really want to know is if i can put those on without changing my jet or do i have to to put the larger jets in my carbs if i do this????

-if i do have to re jet the bike how much bigger jets do i need also what other parts would the bike require in order for it to run right?
by the way im not trying to add hp to it, just hate the factory air box! its a complete waist of plastic in my opinion lol will be selling it if anyone wants it on here, ill let you have first pick on it since you guys helped me out a whole hell of a lot when i got this bike!

(in other news got a set of new handle grips coming from over seas, and new led mirrors since i dont have any turn signals in the front and missing the left mirror  on my bike i figured why pay 40 bucks for a oem mirror and 30 for new turn signals when i can get both in one for only 35 bucks lol ...)

Thanks as always!

If you are installing a high-flow air filter, you will absolutely need to rejet.  Higher flow of air into the carbs will affect the air/fuel mixture and result in a lean condition with the stock jets (which are lean to begin with.) 

The Buddha has mentioned in past posts that high-flow filter and stock exhaust is difficult to rejet, so an aftermarket exhaust pipe may be in order as well.

The factory airbox is a long way from being a "waste of plastic". It smooths out the air flow into the carbs, makes the bike quieter, improves fuel economy, and allows the bike to have a broader powerband.
Jetting without the airbox is much more difficult, and depends on lot on your altitude and local gas blend. That means you aren't going to be able to get exact jet sizes from someone else, you are going to have to do some experimenting on your own.
At best you'll end up with a  bike that's louder, gets worse mileage, makes slightly more peak hp and a lot less midrange. At worst you'll have a bike that runs like crap everywhere.
Good luck. :)

hmm well there is some interesting facts! looks like this guy just ordered him self some useless pods on a impulse buy lol...
ohh well got a good deal so im probably just gonna re sell them if they ever get here from china bhahah

thanks as always guy!

RichDesmond - in a word, yes and no.

You wont lose midrange, all the rest is spot on atleast in theory. Louder - yes you get intake noise. Gas mileage loss, yes but that loss is less than the loss you get cos you're twisting it cos its doing something when you do. Not much experimenting needed atleast not more than stock airbox and pipe.

The biggest reason I dont like K&N pods has nothing to do with any of these you have listed, all of those can be adjusted around or will not occour if you did it right which is exactly the same as if you did stock rejet. In fact take a properly jetted bike with air box and stock filter, remove the air box and slap on K&N and toss the pipe and put aftermarket and all you change is the mains and adjust the air screws. It is that close.

Anyway I dont like the K&N cos its dirty. Worse if you live in a dusty area, or near a construction site, but it is dirty in all circumstances.

Cool.

I actually ordered a off brand filter from china lol... im gonna try it out see if i can get the bike to run right or not.. (def leaning towards the NOT part after reading all these comments lol) then let you guys know exactly what the problem is going to be! it was only 10 bucks so you live and learn right...

The main reason i want to replace that air box is because it is just to much of a pain in the a$$ to put in an take out when you want to play with your carbs.

Would the lunch box style k&n filter cause the same problem?

Doesn't that mean the filter is doing its job? o.o

Buddha meant that it permits too much dirt into the engine. I've seen some real-world empirical testing that supports his statement; someone rigged up a Miata with dual air filters, and compared how dirty the secondary airfilter got when running it behind K&N Filter vs stock. Found that the K&N permitted significantly more dirt for a very very small increase in air-box pressure.

FWIW, the airbox on the GS500 appears to be designed to fill the available space in the frame and reduce intake noise, rather than for massive power. It also serves an important function as a support point for the stock carbs. Be aware that by removing it, you lose the intake trumpets, which, from what I've heard, can cost some power, and create a few turbulence problems for the CV carbs.

That's a reason I've not gone to pods or lunchbox - those carbs together are a lot of weight to hang from just two clamps - incipient vacuum leaks ? ?  waiting to happen ?

This was never a problem on the 89-00 ... or even the newer ones with 89-00 boots. The boots you get nowadays are garbage. They let carbs slip out too easy.
Of course you can always brace the air filter to the airbox or tie the carbs into frame with a nice fat string.
Cool.
