Topic: Pods. What do you think?

[thelowmax]

Anybody have any info or opinions about pods? Is there a ratio for air intake, jets and exhaust, or something like that? Just curious and I can't find the thread that MUST exist on this. Anybody?

[tomkimberly]

POD debates are much like oil debates.....     

BTW, use Google and type SOHC4 pods and you'll get over 21,000 hits.

Pod Debate?  Please Pass the Popcorn!

[Powderman]

Unlike oil debates the effects of cheap pods has been proven why they are useless on most applications.

Dude, you have like 200 posts, this is not the time

OK, I'll start it: DON'T. You'll hate the results, and they can't be 'fixed'.

You can make pods work.
You need to tell us the year and model.
If it is the 77-78 model I can give you very exact info.

Every other concern must already be fixed. Carbs last.

pods work great,just place them carefully and accurately in the rubbish bin and thats when they really shine,or just sell them to some dumb #$%*,along with your old sneakers and call it a cafe kit or some#$%*?

I have pods on my '77F. The only advantage that I can see over the stock air box is that they look better - but that is of course, very subjective.

As Lucky says, they can be made to work, and well too - if you don't mind putting the work (and dosh) in to get them right. I can totally understand those that say they're just not worth the bother. It really doesn't seem to make a lot of sense to undo what years of R&D at Honda has come up with.

A couple of suggestions if you do go down the pod route. First off, get decent ones - K&N or S&B are both good choices. For normal road use, I don't oil 'em - they're finnicky bastards and too much oil will upset the jetting. Second, make sure you support your carbs (wired to frame?)as without the airbox all the weight will be hanging on the unobtanium inlet rubbers.

Third - if you did a search for this you sure as hell didn't do it on this site!

Somebody tried to tell me I was wasting my time trying to get pods to work on my '74 CB750. Turns out they were right. I spent a lot of wasted time and effort and money screwing with pods and never could get them right. Oh, I came close and tried to convince myself a couple of times that they were fine, but, NOT. Finally, I took a good look at the stock air box and the rubber thingme's that connect the carbs to the air box and I saw the reason why pods will not work. The rubber thingme's that connect the carbs to the air box are actually velocity stacks! The carbs will not work without these velocity stacks.

Here is an interesting article all about velocity stacks.

So, don't leave home without them!

Wait one min here
just cuz your stock airbox has velocity stack style boots means nothing with the airbox on the carbs are just getting the same amount air all at the same time so the fight with air temp humility elevation you know above or below sea level is a little easier to deal with  pod filters straight air flow a little harder to tune yes cuz #2&3 are going to get warmer air intake n your ex pipe all so comes in to play because of back pressure if I'm wrong on these details plz let me know but just because the style of boots you on your stock airbox no

Read the link I posted above to understand about the "velocity stack" design of the stock couplers and why they work and why the cheap pods don't. If you can't figure it out from there then you aren't smart enough to even own a bike you should be working on.

[lucky]

The stock Honda air intake system does include rubber velocity stacks.
Velocity stacks are a convergent duct that increases the velocity of the air.

Also remember that the stock air box inlet is only about 1/5 the size of all of the carbs intake areas combined. Go look at your air box and you will see just how large that hole is.

So if you use velocity stacks and some kind of filtration is the best.
A lot more air will becoming into the engine and you will need more gas to go with that, and not just the main jet. The slide needle will need to be raised and the idle jet will need to be increased in size.


Many people say pods just do not work because all they ddid was put larger main jets in and that was all. No matter how big that main jet is  it still will not help the most critical part of the throttle range which is the 1/4-3/4 throttle range.

One forum ( I will not say which one) has people running it that say to never increase the size of the idle jet.

Different web forums have different people running them and if you do not do what they say you will be bullied.
Don't be bullied. Just make one change at a time and when something works use it.
Just do not listen to anyone saying you cannot do it.
MAny racing motorcycles have used pods and other things and they worked.

The thing that gets me are the people who run pods and say they work fine. They have no idea how much better their bike can run with the stock airbox. Without dyno testing you have no idea how much power you have lost and in what range of the power band they may or may not be working. just because it may work better than the crap tune you had before does not mean the pods are an acceptable improvement. I doubt anyone can prove the have a performance improvement over the stock set up.

So no part of what I said has doesn't have any value to it so I have no idea what I'm talking about is that what I'm reading ?

 Not strictly true, but, I have 40+ yrs working on motorcycle carbs 
 If you don't have 100% understanding of how your carburettors work and what is going to need modifying, don't mess with it, you can't make it better (particularly on a stock engine)
 Anyone who says it's 'fine' by just fitting bigger main jets and moving needle obviously doesn't know how the bike should run
It isn't impossible to get right, but, it isn't as easy as a lot of people make out
If your not comfortable drilling holes in carb's (and even iff you are) it's best to leave stock airbox in place
If you do a quick search you'll find out how many people reverted to stock
Personally, I very rarely increase pilot jet size, the stock airbox has virtually zero restriction at idle~3,000 rpm so increasing pilot jet is compensating for a problem somewhere else.
If you put bike on dyno with gas analyser, you'll see very rich mixture.
The Gary Nixon bike isn't stock, apart from the 836cc motor you don't know what cam is in there or what porting has been done, plus, just having a video of running bike is worthless, the only thing that could be useful would be the printout showing fuel curve and HP/torque

I bought a K6 project a couple years ago for real cheap, came with pods and a very small muffler with no baffle, basically open exhaust.
When I got it, I put in fresh gas and a new battery, started right up, but had a miss.  Found the spark plug cap was not fully attached, clipped wires and installed caps.
Started it up and it ran great! I was in the camp that pods were trouble but I now know better.
It may have not been the fastest but was one of the best running bikes I have ever had.
I sold it to fund the purchase of my Z1.

I dare you to read exactly what you submitted here and make any sense of it.  No punctuation, nonsensical wording.  Grammar that would make a five year old say HUH, (unless it was their twin sibling)?

And you ask why no one believes you?  I wonder if they can understand any message your intend?  I can't.  And, I put some work into trying to parse the post.  The total gist I got is that you like pods.

Anybody looked at the FAQ?

Glad it ran well enough for you!
How do you know it ran as well as in stock configuration?
How do you know what was done to the carbs you had inherited?
Ever do a timed quarter mile?

Your "test" has no control group with which to compare.  Unknown changes and unknown results leaves an unsupported testimonial, that can't be differentiated from a shill.

Further, any test case of one is inconclusive to apply toward the greater population.  Science vs. religion is what the pod debate boils down to.

Well I'm sorry that my grammar is #$%* and yes I do understand what I said I apologize to everyone that didn't.  I guess all I was trying to said is it all about how you tune the bike because no matter what carbs will act different when its cold or hot or if you change elevation. again Sorry for my piss poor grammar

I do not know how this particular bike ran in stock configuration.
I also do not know what was done to the carbs prior to the purchase.
No, did not do a timed quarter mile, it was not a race bike.

This was not a "test", just a "report" from my personal experience.

Don't say that a bike with pods cannot run good, it simply isn't true.
