Save your stock airboxes!!!

[bill72]

Recently purchased a 1985 SuzukiGS700ES. The stock airbox had been replaced with uni-filters. Idling was terrible up and down, constantly stalling out. Well I found a stock airbox w/boots, clamps and filter for $30 on ebay from a guy Tim odidle store on ebay. Shipping was fast. Stock airbox is now on bike and bike is running 100% better. Also replaced rectifer. Still waiting on a seat cover and forks are leaking at valve. But other than that bike is running great. Riding everyday!

Im with you on the keeping the stock and xnay on the pods. They may look cool and all. but they are a pain in the ass too get em too run right. Not too mention the correct mixture of air, fuel so your plugs read right. I got a kz 650 that some one put pods and didnt take the time too rejet her. I am bidding on a used airbox for that one soon.

If you install a Dynojet StageIII jet kit you won't have a problem.

Oh yeah, that assumes you are running a good quality header.

I also agree on keeping the orginal Air Box. I have a 80 1100E with a 1166 kit and from what I am told the differance between pods and the air box are not that big of a power differance. I have thought about trying out pods but my bike runs so good right now that i do not want to mess with.

Hey bill72 I already had a number of items book marked from that seller. I need to spruce up mine as it may go on the block. Looks like you may have beat me to the airbox ;-) . Mine idles good, runs smooth but does seem a little lean. When I give it some throttle, sort of weak for lack of a better term.

Couldn't one restrict the airflow to the pods, and in effect create an air inflow similar to the factory airbox?

The best way to run pod filters is behind a set of mechanical slide carbs. Then you will see the difference.

 

[Guyver]

Mechanical Slide?

Mechanical Slide?

Do you mean the Mikuni Flat Slides? I have a set that I intalled on my '82 Katana 1000 along with Pods and a Jardine 4-1. It's at the shop getting the carbs synched. Do you think I might need to rejet the carbs? ~Gene

That's what I'm running now on my 83 750ES, and it absolutely howls! Flatslides and pods (Thanks again Ed), and a V&H 4 into 1, with the stage 111 kit, and no problem...

TOTALLY AGREE!
Stock intake= relatively painless jetting and consistant running.

Dumb question maybe? Anyone?

Back in the early days of drag racing (early 80's), it was found that the shape of the factory air box inlet rubbers were shaped like a velocity stack. Racers including me were running these factory stacks on bored out dirt bike carbs with no filters or box. They made more HP this way than with open carbs...Look inside the box and you will see what I am talking about. They have a very nice shape and I would really be surprised if you could get more power out of a set of high dollar pods versus the factory set up with a new factory (or better if there is one) filter with the air box lid off ..........BadBillyB

 

[frenchbiker]

one thing to consider when you removed a stock air box is the airflow increase because of the restriction (1980 gs1100et have only 3 very small holes at the bottom of the box).when you change for pods you have to rejet your carb to match the new increase airflow.you are rigth it is a pain in the ass to adjust it correctly,the stock needle jet can not supply enough volume of gas for midrange because it is too big .but with a dynojet kit you get a very good result, it run faster and smooth ride in all rpm range .my gs 1100 is overbore to 1166cc with stock cam,exhaust and carb

n.b: the airflow increase don t affect carb idle circuit so you have to check your carb if you got poor idle, airflow increase affect the medium to high rpm (dynojet kit instruction sheet show no modification for the idle circuit )

I may have my stock 1100 one if anyone needs to go back. I plan to stay with my little K&Ns.

 

[jm_foote]

Any thoughts on using a K&N filter in a stock box?

 

[speedy400]

KEEP IN MIND!!! flat slides dont need the same flow characteristics as CV carbs. Seems pods are only bad for CV carbs not flat slides.-darren

 

[Road_Clam]

I am NO CV guru, but I have been told by some very experienced Suzuki tech's that CV carbs need to sense a constant controlled vacuume within each other to efficiently operate the slides. When you add pods you basically cancel this "area of vaccume" around the carbs. This theory in over my head, but i'm just passing it on.
I do somewhat understand, as I remember my old '90 Kawi ZX10 would not rev up without the airbox in place.

Some members have good luck with pods MANY are ready to take a 12 guage shotgun to thier podded bikes.......

IMO K&N give better airflow at the expense of quality filtration.

Life would be a whole lot easier if they had just put a single 4bbl carb on there ! Then we could just flip the lid over and get that really cool sound :razz:!

Also no cv expert, but I will second this, the slides work off vacuum of the intake velocity/venturi, the more velocity(speed) of the intake the higher the slide rises. High pressure seaks low pressure theory. There is a perfect diagram to explain this in my theory book for the motorcycle school I am in, but I cant find it, if I find it I'll throw it up on this.-darren
