Questions about Pod filters

[DrunkenMistake]

Hey guys and girls,
I have been considering removing my airbox and adding pod filters on the hyo, Obviously I will need to get it rebalanced and rejeted,
What im more concerned about is having them on the bike full time, as I ride in all weather and the bike sits outside in the wet if its raining while im working,
So first question is,
Is it possible to do something to them to prevent them from getting choked up with water?
And besides weight loss would it create any noticeable changes?

Noise, mine got alot more induction noise.

Depends a lot on how well designed the airbox is, if it is restrictive you'll get some power gains, if it is very well designed you may lose a bit of power, or shift the torque around a bit. They will be tucked up under the tank won't they? so rain shouldn't be a problem. Some find pods a bit noisier, but I didn't notice any extra noise, but I did do the exhaust at the same time, which got a bit louder, but a much nicer sound.

Keep it above 9000 RPM ... the induction noise will be the least of your worries ...

But a quality cover will stop most of the problem ...

I had an F1 CB750 Honda (76) with pod filters fitted. With four pods fitted, the outer ones often got wet riding in the rain and caused running roughly. A double pod (one pod for two carbs) in the wet the wet pods caused a roughness ... but not as noticeable ...

Just a downside of pods ... (the FIX - just don't ride in the rain)

Yup power band starts at 9.

Only if a RED one was fitted ... :innocent:

Yup its the red top motor.

thanks for the replies, They will be tucked up under the tank been a vtwin, the can is getting done in about 5 -6 days when it gets here from the UK, and ill be blocking up the retarded AIS (Pear valve) scares the shit out of me everytime it pops
The pods was just a thought that was there,
May be a little more hassle than it is good, so I may leave it for now and see how we go

I only went with pods due to them being so much cheaper than a new stock filter. But it does rev easier and uses less fuel.

See if ONE pod filter can replace the existing filter ... inside the airbox. Don't give up yet.

How do you mean?
Sorry not so savvy when it comes to the filters, im still earning bike stuff without breaking things :P
To my understanding its one pod for each carb? twin carbs two pods, the standard air filter is square



OR do you mean taking the filter out of the box and fitting a pod over which ever space is made? :blink:

The basic theory is more fuel/air inside the combustion chamber ... the bigger the bang ...

ie: ANY improvement has to be good.

But remember the breathe OUT stage must be as big ... and be able to breathe out as big.

The idea being less restriction of air/fuel going in and less restriction coming out.

The key being ... the balance of both.

you can put a shield around the pods, might work for rain.

try it out and see, if u dont like it, put it back to stock.

[caspernz]

Have you thought of the K & N option? I'm a scrooge so I got the K & N mainly because you can wash/clean the filter, re-oil and refit in the standard airbox. It's one of those things I do on most of my bikes, 'cause it's been cost effective and the engine seems to 'breathe' better as well. No re-jetting needed, unless you want to go with the high airflow option and re-jet. Kinda pointless really, just open the throttle a bit more....

Will give it a go, I just dont wanna go through the rejetting process then find I need to go back,

I done a little more research and a common change for my bike is no filter at all, but some fine mesh in its place (to keep shit out) not overly keen on this as its not exactly fool proof,
The other is fitting them within the air box case, im a bit sick at the moment so working in the garage isnt really an option at the moment, but when I get better ill take the tank off and the air box and have a look at how it is set up and see if I can squeeze the pods in there.
Plan b. would be to (after checking it out first off) to get another air box, and modify it to allow more air flow and give the pods some room and protection, will let you all know in a couple of weeks, have some other bits and pieces to do before I try this,
first on the list is blocking off the pear valve, I have one bolt holding the bottom of the exhaust in place that doesnt actually need to be there, when I lowered the bike we found it wasnt going to come free, and a few broken ratchets (not cheap ones either!) and 8 hours of drilling, hammering, kicking and what have you, got nowhere, so Ill need to get this out haha, thinking of using a butane pencil torch and ice then smacking the head off with a cold chisel (cant get in there with a grinder anyways)
Then by that point I could be moving out, so depending on funds at the time, I will give the pods a good go.
Thanks for the advice guys.

There's a standard K & N filter that'll fit in your airbox without mods. You'll get an improvement in performance, without the hassle. If ya wanna go for pods just for looks, sure....

Yeah, but pods are like 1/3 the cost of a K & N filter,
and im looking at losing unsprung weight, I have shredded about 1.3 kilo so far, with another 3.3ish about to come off as well,
This is a fat bike.

[Sable]

Generally best just to leave the airbox, lots of volume and a good chance you'll fuck your carburretion. A lot of the cheaper pods have more flow at the cost of less filtration :whocares: DNA pods seem to be quite good for the money

I have herd alot about the DNA stuff, as I said this isnt anything in the plan for soon, just tossing about ideas.
Thanks for the idea though

[caspernz]

The airbox is considered unsprung weight? So what do ya call your wheels then?

:woohoo::woohoo: lmao

remember they spent 100 000's of dollars on R&D for that airbox that you will fuck up.

If you wanna go awesome, like me, go open carbs. (no air filter/box/anything, keep your velocity stacks tho)

you will need to rejet and a free flowing exhaust (go up a size in extractor diameter) and you will need a dyno tune.

you will loose low down power maybe a bit of mid range. but you will gain the most up top possible.

Then again, you have a vtwin, which is all about the down low?

it worked mint on my cbr250, the noise was amazing. induction is louder than the exhaust, and the exhaust was a straight pipe.

course it will damage your engine.

:woohoo::woohoo: lmao

Sometime you can even run the bike on it ... :shutup:

What he said, for looks fine, for anything else its a stepbackwards. RC211V's have airboxes ................

I have just removed my pod filters from the XS1100
they were good for the first 1k, but then the bike started running rough
because I had not thought to put a support bar to the back of the carbs, which were once supported by the air filter box housing mounts. The weight of the carbs and the filters caused them to "bounce"
Result was that my inlet manifolds cracked, and were sucking air.
Now I need new manifolds,
I like the look, and the induction sound they create,
but the performance gain was not worth the effort.
The cost of replacing the inlet manifolds was not worth the effort
the loss of enjoyment cause I cant ride my bike till the new ones arrive, again, not worth the effort.
If you fit them, be sure you support them and the carbs with some sort of stabilizer bar,

[DrunkenMistake]

(Im on my phone as we still dont have internet at the new place so excuse poor typing)
I have gone over a few ideas and im thinking of having a y pipe made up and putting a car sized pod at the top with something to hold the carbs etc in place. Or once again ill get a second air box and open it up with the pods inside

[FROSTY]

I dunno all the ins and outs of hyusungs but If they are similar/the same as the SV650 then the actual filter really is the least of ya worries. You need to get the air TO the airbox and up in through the filter. Theres been some mighty fine work done with opened up factory filters and lifting the front of tanks. I'm not sayiong I'm right just hey why reinvent the wheel if the answer is right there

Have been doing some research and digging around and your not far from wrong, seems to be some of the common things people are doing WITH pod filters on these bikes is having the pods mounted close to the openings of the fairings at the front one on either side and having them connected to the carbs from there, forcing the air into the pods from the get go,

It is on hold at the moment though as I have to now replace my entire charging system. :brick:
