Unfortunately, another pod post

[Suzukian]

If your answer is "No", then the basis for your whole theory is "No". The scavenging by the two outside pods make the center pod suck much more chaotic.

This whole set up is bad in any event. He would be better making a Chamber for each pods to have the air coming in from the front, having made 4 larger than the Pod Filters, as large as possible, so that they fit, then use PVC or even sheet metal and have 4 isolation tubes mount to the sheet and have the air come directly into the pods, through individual cylindrical openings.

You answer "No", but write you don't understand what I mean. This whole set up stinks. Make a flat plate with 4 holes and mount the cylinder (in the tube sense), You would (SIC) get the same unrestricted air flow without the associated off idle hesitation / bogging and that's it. Sound familiar? See pic below. :smiley_simmons:

Are you on drugs ???
Those air box pic's have nothing to do with me and i have not posted any "theory" regarding them or even commented on them..
My answer detailing the function of the main air jets was in reply to ROB S'squeryand the information contained in that post is FACT not theory .
A theory is an idea that hasn't been proven whereas the air correctors have and if you are still in doubt you should take it up with MIKUNI and other carburettor manufacturers such as Weber and Solex etc who have included them in their assemblies for over 40 years.. Or maybe just Google - Air correction jet or Main air jet ..
Your random post cryptically quoting me gave no indication as to the subject you were refering to so i had to guess by the wording it contained and the previous unconnected posts.
As for the three pods on the air box serving four cylinders, it makes no difference how many individual inlets there are serving the airbox's void as long as they provide suitable airflow to constantly maintain the airbox's internal capacity ( which is NOT divided ) and to serve the engines demands and if they flow the same or similar to the stock set up then air correctors won't be needed.

Any further comments on the design should be directed at the airbox pic's OP UNFOCUSED who doesn't appear to have any problems with the airbox mods he has performed and i don't see any reason why he should..

Oh, I'm sorry, I thought you posted this:

.............When you remove or significantly de restrict the airbox, the off idle bogging / hesitation that results is caused by higher atmospheric pressure in the venturi and over the needle jet ( more air volume but moving slower ) ...
This impedes fuel delivery from the needle jet tube at just off idle rpms and creates a noticable lean spot which manifests as a drop in power around 2000 rpm.
Contrary to what many believe this is not a pilot jet or needle jet issue but on the transition between the two which is the area the air correctors have the most effect...
The misguided method of fitting larger pilots and lifting the jet needle as a "cure" only serves to over richen the entire lower to midrange fueling and mask the issue which also reduces mpg and top end power by up to 25% in the process..
The effect of the air correctors feather off proportionately as the revs rise which maintains the correct A/F ratio at higher rpms and results in a sharper throttle response, increased mpg and overall power by 2 to 6 hp on average.................​

No!
How do you come to that strange conclusion ???
You get the same unrestricted air flow without the associated off idle hesitaton / bogging and that's it..
The air corrector ( main air jet conversion ) targets the cause of the off idle lean spot without detrimentally affecting the rest of the fueling curve and power unlike the grossly ill concieved method of just throwing more fuel at the issue that continues to be inflicted by those who have no idea what they are doing.​

So I see this was just mental self gratification (the word I'd like to use would probably edited). Considering you had so little to offer to the OP, you sure posted a lot of words. Stiff upper lip an all that. Cheers, it's all good. I don't run pods, they are stupid.

I run velocity stacks on my race bike, and on my '73 MG Midget, I run Side Draft DCOE 40mm Weber on my highly modified 1275 cc Midget engine, with a 10 degree more duration Kent cam, forged pistons, Moly Rods, etc.. I will be changing the intake for the Webers to suck air in from outside the car, and not the engine bay. Maybe you might want to check out the Vintage Suzuki site in your country. Those guys know how to build bikes.

The original OP asked for pod jet kit recomendations which is exactly what he got in as few words as needed in ONEreply and he has now acted on it .
The airbox has no real connection to the OP.s first post and i never commented on it.
My one other reply ( to anyone but you ) was in response to a direct question to me from ROB S and not just posted indescriminately for the sake of it so please get your facts correct and free from exaggeration.
Randomly quoting my answer to ROB S and then trying to form a loose relevence to the totally unconnected airbox post makes no sense and if it does to you then you have made a very poor effort to convey your logic and until i develop the power to read minds i will remain forever baffled as i suspect everyone else will too..
Non of my answers prior to your surreal interjection referred to, responded to or even acknowledged the airbox post in relation to the air jets or any other matter so frankly i still have no idea what you are on about and if anyone else reading this can enlighten me with a coherent explanation on what i seem to have missed please pray tell.

 

[Nessism]

I think that airbox mod, with three pods, is kind of nifty. Very unique. It reminds me of guys running airboxes without the lid installed (a different type of airbox than this version.) The 1100E guys do this all the time.

 

[Rob S.]

Well, I have (APE) pods, and I have NO "off idle bogging or hesitation." :glee::glee:

If you want to speak to one person, send them a P.M., the notion that you were responding to one person in an open thread, and expected no responses on your explanation is ludicrous, as Rob S. stated

Well, I have (APE) pods, and I have NO "off idle bogging or hesitation

seems to vindicate my response. Either there is side boggling, or there isn't. Also, not responding the OP's original post is called "Off Topic", it is not within forum etiquette, and if you post up half baked explanations of tried and true theories, you will be called out on it. He may have been better off putting one big oval filter covering all 4 holes, and mounting that, removing the side pads of the air box completely, maybe. Boggling would not be an issue as the chamber inside the one filter would have been a reservoir for all the carbs to suck air from. Not one instance of exaggerating. I actually kind of agree with you.

Those Pod filters let is too many particulates, adding even more, well, they're your rings, you can destroy them if you want them. Foam dipped in oil is better. The original air box is best for filtering, for high performance racing where longevity is not an issue, just run velocity stacks. Run trombone type tubes to the front and get nice clean air from the front of the bike. With some finger holes, you may be able to play a tune.

Still have no f**king idea what you are talking about and you persist on quoting the airbox post which i have never discussed and don't care about and now you are bleating on about destroying MY rings which haven't been mentioned anywhere either.
You have no idea what filtration methods i use on my road and race machines so where did you conjure that from ???
Do you have any idea what you are talking about , "SIDE boggling " what the hell is that ???? . Clearly not!
And as for forum etiquette, you are the poster that is repeatedly persuing an off topic subject, Not me..

Try Senna pods they make you go fast.

Meant "Bogging", not such a quantum leap considering your spelling. Do you read what you post? I never posted anything about your bike(s), ever hear the expression "you in general". "My, thou dost protest too loudly!".

Bye! Have a nice life.

As Zed1015 said with VM carbs air corrector jets are the solution.

Except the VMs fitted to Suzukis have air screws that control the air entering the pilot circuit, so air correction it by way of a flat bladed screwdriver. They also have a fuel (mixture) screw. From memory Kwaka fitted VMs had an air jet in the bell mouth with adjustment provided by only a fuel screw. The Suzuki VMs are a combination of both pilot systems shown below.

The Kawasaki VM's have either just an air screw on the side or just a fuel screw underneath depending on year and model to adjust the pilot circuit with the VM26's having either and the vm28's solely only an air screw and never a fuel screw.
The Suzuki VM's whether vm22,24,26 or 28mm have both air and fuel screws present and they both control the pilot and pilot bypass circuit respectively.
All Suzuki and Kawasaki VM's have a pressed in main air jet in the mouth of the carb to supply air to the needle jet tube.
Air correctors do not adjust the pilot circuit but the main air supply to the needle jet tube when threaded and installed ahead of the pressed in main air jet and work in both Kawasaki and Suzuki VM.s as well as some Suzuki, Kawasaki and Yamaha CV's.

Ah, thank you. I stand corrected. Air correction is for the main air bleed for the emulsion tube.

 

[zed1015]

Yes! Correct.
The air correctors allow the same adjustabilty to the air bleed passage as is present on the VM smoothbore versions which are designed to operate without an airbox .

second that :encouragement:

Not sure how this got to this point however, let me explain. I custom built my filter housing based off of a FACTORY housing. I pulled out the center plate (the divider plate the the factory air filter installed on), built a new one with x3 2 1/8 exhaust pipe and 60mm pod filters. The bottom/rear was removed because the original opening is less than optimal.

 

[unfocused]

This pic shows what was removed

 

[unfocused]

The main reason I wanted to do this - The factory air box has factory velocity stacks. These are tuned into the original engine and I purchased new ones.
These assist with the hesitation noted when switching from factory air filter set up to pod filters.
The clean air chamber is fully sealed so I can ride in the rain ( hello, I live in Florida ).
3 pod filters are cheaper that a factory filter or replacement and these are washable - like I'll ever need to wash them...
As mentioned, this fits in the factory location with NO modifications needed to anything else. I also removed the engine breather tube and relocated it as shown.
​
The only noted issue is I'll need to protect the left side pod from the chain slinging all it's good stuff all over the place.
If it restricts the performance, I'll go a different direction. No one's getting hurt and it's not a waste of time to research your options. Especially when you can...

Not sure where others get off stating that it'll never work or it's a waste of time. It's not yours. You didn't research, do the needed work and you didn't install it.
Also, if my mechanical ability (40+ years of throwing wrenches at stupid people) isn't up to your expertise, then so be it, but keep your poor attitude to yourself.
This is a community and sharing is part of it even if you don't like it !!!

This is MY GS750 - bored out to an 844 and has several other goodies.
Then I have a GS710 in process - my build - my bike - going racing.
Let's not forget about the GS550 bobber that parts are being gathered up for.
Amazing how one can sit here and chastise others for doing what they're not doing...

Also, FTW - this is what I purchased in February of 2023.
I was riding it in May 2023
