Pros and Cons on Pod Filters for Carbed Monsters

[bunnyman666]

I am a junkie for extra coolness factor as well as wanting to squeeze a bit more performance out of my scoots. So, I got the free-er flowing cans (couldn't spring for a full system), and I am now considering going with a pair of K&N pod filters.

Yes, I know this will require re-jetting of the carbs, etc., etc., etc.

What I ask is if any of you who has EXPERIENCE WITH THIS MOD, whether it be from your own bike or some who has worked on a bike with this mod has an opinion on this, and whether or not they would have gone back to the old airbox. I will rarely ride the bike in the winter, though I will probably run the bike almost every day during the winter.

Thanks in advance for your answers.

1 you have to remove the case recirc setup
2 you can have water problems in rain
3 you may need to retune your carbs

that's about all I can think of.  I have done it on previous bikes, the only reason I don't on my S2R is the case breather setup.  The more I read about that, the more I am convinced it's a bad idea to remove it.  It is possible to make another one tho with pod filtres, just out of my experience.

So what you're saying is to possibly mod the stock box to shield the pod filters from water. This was somewhat of the direction I thought of. This could prove to be interesting... I am waiting on others to weigh in...

I already removed the case re-circ set-up when removing the "emissions" carbon cannister and box. I also thought of this- The stock box gives a place to mount the HID ballast; that is, if I end up using the DDM tuning HID kit (I have a kit that doesn't work, yet DDM says my ballast is ok; hmmm...). The stock box does have it uses...

While I do avoid riding in the rain, it can still happen and I could have some problems. Food for thought...

Thanks.

no.  pod filters mean no airbox at all.  you can cut your airbox lid which gives about the same performance gains as pod filters, but you still have the airbox..

Was a bit confused by this quote: It is possible to make another one tho with pod filtres, just out of my experience.

But if you can't stick pods inside a box, that's fair enough.

I guess I am thinking then of possibly just going K&N with a cut box lid like I did on the last Duc. I should be getting this bike (2000 Monster Dark 750) in the next few days; just gotta pick it up. No, I didn't buy it sight unseen, either. I saw the bike on a trip to my cousin's house; had no way to get it home. My cousin and I already did the "emissions" mods. Bought some Leo Vinces for nearly nothing right after.

Pods do look cool; but if they cause tonnes of problems, I want nothing to do with them.

Again- I will wait to here others weigh in...

This topic gets beat to death.  -1 for the pods.  I know someone will argue this but unless you get someone who knows this set up and has a good knack for tuning or has a dyno, I would stick with the closest to stock config.  I've tried the pod thing on previous bikes just to switch it back again.  Sometimes you can get the bike to run well at certain RPM's while at other rev's it runs like shit.  You have to consider that most stock carbs were tuned(and designed) for use with an airbox thus needing a certain amount of intake resistance.  Some carbs just weren't designed to work with high volumes of air and cant be modded with just a simple jet swap.  It's just some food for though.

FYI:  It took me months to try to get my CB400F-SS to run "OK" with pods.  Dont forget its 4 carbs.  I ended up bringing it to a shop with a dyno and spending a lot of $$ to get it to run decent throughout its full range.

doesn't K&N sell a single unit for those?  one filter element with 4 spigots?

[moto monster]

have them on mine, seem to work fine pay $70.00 for them hated the airbox look 

[bunnyman666]

Not that I know of; however, the stock airbox on most of those bikes is an airbox with one inlet and four outlets to the individual carbs. K&N makes the drop-in filter for that application.

Removing the stock airbox from my Kawasaki KZ650B was a freakin' nightmare!!!! I ended up cutting out the airbox!!!

[bunnyman666]

Now the question is this: has anyone noticed any rain problems when they cut the top of the airbox? I am merely curious about that.

[greenmonster]

Never any rain problems w open box w Mikunis
nor w pods on my FCRs.

I've got this setup on my M900.  It runs fine in the rain... no issues even in a couple of outright downpours (I know, I know... "get off the road and under a bridge, a#@hole!").

Great intake sound when you whack it open, too... but I'd still like to switch over to pods for the appearance.

It's good to hear folks running pod filters don't have rain issues.  I imagine that problem is hypothetical and it might take more than a regular rain to do it.

here's a good question:  Two pod filters or a single large pod with two spigots?

I have seen the latter, I don't know if it was K&N but they will make stuff like that.

I have seen up to four outlets from one large pod; I think it is a custom-built application. I actually see that as being nearly as restrictive as an airbox. I may be wrong, however...

I did see something adapted for a four-carb operation: a small oval K&N with two outlets. One fellow sells them in pairs for the old 39mm Mikunis (i.e. 4 carb KZ's, CB's, etc.,etc.).

I'm wandering......

A airbox would seam better at blocking the heat from the motor since
 high temparature in the carb can make work less effecently since hot air is more dense

I'm thinking about creating a "ram air" so it would force air into the airbox.
It would increasse air pressure in the air box acting like a supercharger.

I'm thinking about profiling my needle to reduce the air vortex in the  carb .
And rejet the carb completly
 
Less vortex= better air flo= increase performance

Pods look cool but some serious is needed to the carb

If pilot jet, needle jet, main jet, pilot srcew ... are confusing therms...forget pods
 

Thats just me thinking.
