Thanks :-p

+Sir Charles nice tip, thanks :) I might try this ...

I use stage tape on the outside.

heh :-p

I was deff gonna say something about that 😏

well pray miss SUBMOTO dont see the video

I think the fact that these carbs are CV, is a big part of the problem

Yeah, it's a bit of a science. I can definitely recommend getting a bike with pods to a professional with a dyno, if you absolutely want to have pods. although I wouldn't suggest having pods on a CV carb. They work better on flat slide carbs like the one I have on my SR500 :-D

+SUBMOTO exactly! well do you think I'll be facing similar problems if i install regular k & n performance air filter.. (not a pod filter)?

Yes, absolutely. even the smallest changes will cause a change. You can test that down to the slightest detail on a Dyno. Whether you will be able to feel it, or if it could be bad for the engine, really depends on a million things. Changing the exhaust will also have a tremendous impact. change it, get it to a Dyno, and then you will be able to adjust things correctly from there :-)

Well, you can definitely get a pod filter, but then you 100%have to get the bike on a dyno, and have it re-jetted by a professional. This will not give you more noticable power, but will just keep your bike from melting down. I was forced to do it on mine, because of the way the previous owner did it. Because he just did it by looking at the spark plugs, he managed to destroy the engine. So I had to have the piston replaced and had to re-size the cylinder. It turns out that it was because he was running too lean because of the pod filter. So I had the choice to mount the original filter, or get help from a professional with a dyno. And so I chose the dyno. It is NOT faster now, just not worse and now the engine will survive. Here is a video about the dyno: kzfaq.info/get/bejne/er6madmKtJPVmYk.html

SUBMOTO Thank you for the reply. I will. I believe I am a Subscriber. If not I will hit that subscriber button. I my other thing is getting a camera so that I can do some video’s here and there. I am new to everything and don’t know jack squat when it comes to bike experience. I do know that the Zuma has a coolant and that people get mad at me when I call the Zuma a scooter. There telling me it’s a new ball game when it comes down to the Zuma 50f it’s a mini motorcycle 🤔okay again I have lots to learn. I am going to get to the video I have so much going on today. Thanks again for the reply and the link to the video. Ride safe. Peace.

Is it the air-fuel mixture being disturbed if I have a EFI(Electric Fuel Injection) system, since he talked about carburetors. Are Pod filter also causing those problems with EFI systems?

Well said, fella. Just change the jets, or use washers to raise the standard ones. It takes some messing, but it will work eventually. I fancy using a Dyno if one is cheap enough near me. Just take time, and play around.

well, they say that for single-cylinder engines, it's best to use a big air filter pod (a bit like what I have on my SR500). I'm not sure what carb you have, but you will have to get it jetted correctly, or you will run the risk of destroying the valves if you run too lean.

Manuel Ribeiro It has a huge influence. but with professional jetting, you'll be fine. Just extremely difficult with a CV carb

chiken You can always use a pod, but you have to take the re-jetting seriously and have it done with a Dyno to be sure. All too many engines are ruined by people who think they can do it by 'ear', or by checking the spark plugs.

Nice, good work! :-) I'm curious what a dyno-test would display vs. stock. It's not impossible, but quite a hassle for most. I've actually never heard of it being done on a 2-stoke first hand, so that's actually really interesting to me, i don't know if it's harder or easier on a 2-stroke :-) How are your spark plugs/plug burning?

Awesome

oh w´man, I would recommend you just get a smaller battery. There are some amazing small lithium or Gel ones available. I have a lithium battery myself. I would try to keep the airbox if you can, and if you have no problem with it

​@@submoto Thank you! sure i'll keep the airbox and will put the battery in a side box

Juan Garces thanks :-)

Some people have managed to get a good mix with pods ...I'm not one of them :-p

+SUBMOTO only "problem" i had whit the pods last year was that all the shiet flyed from my back tire to pods so i had to clean them everytime if it rained etc.....whit some shield to protect them and i shouldnt have any problem......Easy to get good mix.....if you cant get good mix welp then you are doing something wrong.

+TT GarageRat I am on my smallest jet, and have lowerd the needle to a maximum on my single flatside carb, but I'm still getting a rich mixture. This is odd, since you would think a pod and open pipe would give me a lean mixture, but its the exact opposite. It is a brand new carb though, but still :-/ I have been to a number and nobody can help me. The bike in this video was the same shit only worse. Everybody I talked to said "oh yeah it's just an adjustment problem", but after spending almost 2000 dollars on mechanics, nobody could fix it, so I went back to the original jetting and air filter, and now it works. My new bike a completely different kind of carb, and should be a lot easier, but like I said, so far no luck. So next step is going to be a trip to the Dyno, and attempt to adjust it there. I have fingers crossed. But it has been a nightmare both times, and so far nobody has been able to help

SUBMOTO that is really weird, something isnt right if it does that, maybe your carb is damaged ?? have you already checked Andy's Motorcycle Obsessions video of pod filters ? also what size of jet you have now and what size is the carb ?

+TT GarageRat carb is brand new. Doesn't look damaged to the naked eye. I'm at 15 on the pilot jet now. Seems like the problem is when I roll off, or in idle. I'll check out that vid :-) thanks. I'll get to the bottom of it yet some day :-)

JaKen_69 changing the filter and/or pipes will always affect yoyr mixture, but with Fuel injection you don't 're-jet', you 're-MAP'

SUBMOTO Thanks. Ride safe:)

I think that might work. Although I heard of someone who did that on a GS550, where it wasn't possible. I just can't remember why. but in theory, it should work

It must of been the altitude or lack of would be the only thing I know of but then I'm no mechanic either lol For those who want a streetable racer get the crank shaved to race specs you can shed 4 pounds maybe more depending on the bike but definitely find someone who knows how to build a race engine.

I'm trying to learn on my single. I've gotten close, but still not as good as when it was stock

+SUBMOTO Keep at it, you'll get there, it is very satisfying once you hit the sweet spot. If the needle isn't adjustable and need raising slightly, you can put very thin washers under the needle head. The main thing to consider, more importantly than anything, is to do any changes in a very controlled, orderly manner. If you just chop and change jet sizes from large to small and back again you wont know what the hell is going on. Also worth doing an adjustment, and note down where in the rev range it bogs down. Do this for each jet size and/or needle adjustment and it'll soon make sense.

If you change the exhaust, the carbs may need setting up anyway, once you are comfortable working on carbs it is so much easier as you haven't got a chuffing great airbox to remove/refit every time

+TheDaveSausages great, thanks :-)

Motoclesiastes 1:3-5 There will come times of much confusion and false prophets who worship false power. Many will be confused by them.

aah ok bro para comentarte en español mi ingles no es muy bueno lol es que es mi primer video, que moto tienes? yo tengo una cb550f del 77 pero me gustaria tener una cafe

Pues fíjate que no se nota :-D Ah mira! La Cb550f es buenísima moto para hacer una Cafe. La mía es una Suzuki GS550 (cafe racer), y la otra (que no es cafe, si no 'tracker') es una Yanaha SR 250

Wayward Vagabond they DO look pretty awesome :-)

SUBMOTO can't fit them on mine so had to add a breather one just because I like them lol kzfaq.info/get/bejne/p5mbiJaXur3DZnU.html

Wayward Vagabond I busted my engine (cylinder expanded) due to the wrong jetting on my SR500. I learned my lesson, so I can only try to convey that by recommending professional equipment to jet the carb correctly. CV carbs seem to be hopeless to jet though.

SUBMOTO yeah never had to do one, all my bikes have been injected or bought already jetted with mods 👍🏻

+ovo nisamja I actually tried that, but unfortunately it didn't work. something about the flow and square inches of still air etc.. :-/

Bispo On Road you can't find one for sale at all?

Nop it is a Hyosung Karion 125 RT 2005. The Rubber is all cracked up. To make it worst, the airbox side is just an oval hole, making the sealing very difficult without the original rubber...

Hmmm that's problematic. Well, it's less critical on the filter side than on the engine side. I wonder if you could get away with silicone. it doesn't get hot on that side, so it's mostly just vibrations you would have to contend with. not optimal, but a possible temporary fix until you find one somewhere

I'm thinking on making a new air box exit so i can fit a simple hose and clamp it in on both sides (carb and airbox). Maybe glue it to the box exit., something like this: www.pegasusautoracing.com/images/L/3623-PLUS.JPG

That might work actually! but it would still be best to find the original part, it HAS to be available somehow. That's sounds crazy

Well it's not impossible. Some people say they managed just fine. But I have been to three mechanics, and they all told me to go back to the stock filter. I spent a year and a half fiddling with it, and finally decided to do what the mechanics all told me to do. Also, pod filters are horrible in the rain, which can cause water to get in the carbs (which many of my friends have tried. In high gusts of wind, you can also feel a difference, so they are unstable. It's mostly a cosmetic thing, although some people say they can get more horsepower, but from the tests on a Dyno that I have seen and tried, the difference is so small it's hardly noticable. It's mostly a placebo effect. A real pro, might be able to do magic with pods, but for the rest of us, it's just an unnecessary hassle simply for looks

agreed. I have a video and example on that exact issue. We put the SR250 on a Dyno to illustrate that

I absolutely love how easy it is to get to my carb now on my SR500, but I have absolutely no performance gains yet. I still haven't found the sweet spot. Although its a lot easier on my SR than on that 4-inline CV carb set-up on the GS

I actually considered that, but was advised strongly against that. better just to get it jetted professionally

(1 of 3) Great question :-) the answer is, yes, it can be done with CV's, but it is virtually impossible to do well. Check out this forum for reference: www.dotheton.com/forum/index.php?topic=31136.0 'Flatcurve' puts it quite well :-p My real life experience, reflects this to the 'T'. Getting the bike to run with pods, is not the same as getting it to run well, or better even. If you want to run with pods, there's a better chance of achieving actual improvement in performance with a conventional throttle slide carb. Bare in mind, I'm far from an expert, just a dude who has experienced the hell first hand, and a dude who know guys who have had the same problems. This is how I had the reason explained to me by a pro: CV carbs, use the air box to create a very specific 'micro-climate' within the air box, and feed each carb with the perfect amount of air in equal amounts. (Constant velocity=CV) ...(continued)

... (2 of 3) It's an extremely sensetive system. But this means that it can regulate the air flow regardless of altitude and other external climatic variances. Now here comes along a cafe junkie, and just removes that super sensetive micro-climate, and just 'opens the door' and allows for a free unregulated air flow. They JUST won't work right, since they require a certain amount of air resistance to create that vacuum that's created by the difference in atmospheric pressure between the engine and the butterfly valves. Even after a re-jet, they are WAY too sensetive, and will react to gusts of wind etc. If you just put pods on conventional carbs without re-jetting, you will simply create a hotter engine due to more air flow creating a leaner mix, but the bike will run without any other real symptoms (up until the point something melts ofcourse), but if you do the exact same thing on a CV carb (or even just remove the air box), the bike will jolt, and cough and act all crazy like, because...

...(3 of 3) a CV carb needs RESISTANCE to function properly. Read the forums out there on the subject. There's always someone that claims he got it to work by re-jetting and can now EVEN DO WHEELIES!!! ...wow :-/ But as far as I have seen, none can claim good/better performance (verified by a dyno-test for example). It's a just a ROYAL pain in the butt, and for nothing other than trying to look cool. ...and running a lean engine might feel like a slight power increase, but it will ruin your engine, which is most likely what those people have achieved hehe :-p (Pump) Flat slide carbs, like the TM36 (non-street legal race-carbs) are a WHOLE different ball game though. I know a couple of Expert mechanics that have managed to squeeze 3-5 HP more with pods on those. But I don't know any 'regulars mortals' like me, who have managed to get even close to that. And absolutely none that have gotten any sort of improvement out of CV's Hope that helps :-)

Well if you have access to a Dyno and someone who knows their stuff, then you might get a bit out of it. In most cases the difference in how is not something you would feel, but rather more about shaving milliseconds off of lap times. It's also quite easy to get wrong, and 90% of people who do the pod thing, end up losing power, because they just think that looking at the color of the spark plugs is enough. It's not. Also, the ease of it depends on the type of carb. In my experience, trying to pod filter vacuum carbs is a nightmare. It's MUCH easier to do with a flat slide carb, which is the set up I have on my bike now. Whether I have gained HP ...I doubt it. Probably lost a bit, but it works now, which took awhile to get right. ...but if you race, and you have an expert on your team who can Dyno and jet, then you should be able to shave a bit of time off of a lap. Doubt you'll 'feel' the difference though

SUBMOTO hey thanks. I have no race team or anything like but I do have a few shops around town with dyno services. And with the more research I’ve done I found out I have the CV carbs which like you said are a nightmare to tune with pods. So I was thing of just switching to a new set of carbs and came across these.I haven’t found much info tho outside of there website. murrayscarbs.com/product/nighthawk-650-mikuni-carb-system/

Ah yes, the VM34. Good choice. I switched to TM36 myself. ... although there are some good solutions for covering up the original filter. From what I have been told, the thing with vacuum carbs is that it was invented as a solution to riding where air density sould change. With traditional carbs, if you ride in the mountains, you would get thin, then thick air etc etc... That would affect the mixture, so they invented vacuum carbs, which would create a 'Micro-climate' in the air filter, and it would basically only suck in the air it needed. ...that was great and all, but then came Fuel injection. So if you remove that 'micro climate' and just slap a pod on there, you're gonna get a whole lot of circus in your carbs :-D ...at least, that is how it was explained to me.

SUBMOTO hey thanks for your input. Pretty much what I’ve been reading everywhere about pods, even tho I don’t wanna hear it 😢. I don’t wanna hear I’m covering up the original filter either I thought this was an upgrade. I don’t know much about this system beside the website. I just assumed with the price and the style of 2-1 pods that there’d be some type of performance gains. I guess I’m used to newer bikes where more air general means more power and tuning it is as simple and plugging in a device to the ecu.

@@ridin_low193 well, with the VM you'd definitely be ok. I'd be surprised if you can feel a difference, but it would be fun to get a lap time before vs. after or a dyno before/after. ...for science :-D

Well, it might be. It could very well be a dirty filter, but before you worry about that, make sure to test the spark plugs straight after a longer ride with a relatively steady speed (40-60 mph), then hit your kill switch while you're riding (at a safe place), pull over and check them again (be prepared for a backfire). The reason it's best to check it like this, is because low speeds and a lot of start/stop riding will automatically darken your spark plugs. Also, if you've just used a choker to start (which increases fuel flow), that will also darken them, so for that reason it's best to 'ride them clean' before checking them. Some people who ride in lots of slow stop n' go traffic, sometimes change to hotter spark plugs (so if you for example use B8ES, you may want to try B7ES). That means that they work better in the city, but if you hit the highway, they may burn a bit lean. There is also the possibility that you are running with the wrong spark plugs, so check your manual to make sure you are using the right ones first :-) Hope that helps

+SUBMOTO You say the hotter plugs make it burn lean, but I don't agree. The hotter plugs will just transfer less heat away from the plug. Too hot plugs won't change the mixture, it will only change the temperature of the plug itself. If the plug is too kold, it won't burn the carbon deposits away (could look like rich mixture). Too hot, and it will damage the isolators. I agree about using hotter plugs for stop n go traffic thou, because it makes for lower rpm riding. I just noticed you ride around in Copenhagen, are you born in Denmark? For så behøver jeg jo ikke skrive til dig på engelsk :-)

+Bjarke Andersen You're right. What I meant was that they will burn lighter (color-wise) That being said, I have tried hotter plugs, and the bike started popping and the acceleration was flat. So although it may not have run lean per se, the symptoms were quite similar. ...but with these old bikes, who knows why it acted up like that. sometimes only the gods know why they act like they do :-p

I agree, and yes old machines live their own lives sometimes ;-)

Yeah, I just tried that the other day on my way to sweden. It was so windy over the bridge, that the bike kept wanting to die :-p but I guess side covers could prevent that

+Anton “Anton125X” Lundgren You could, yes. By switching to air-pods WITHOUT re-jetting you will increase the flow of air and end up with a lean mixture (too much air, too little fuel). This will get your engine too hot and you could end up burning something up. If you re-jet CORRECTLY, then you should be fine :-) Here, check out my vid on jetting: kzfaq.info/get/bejne/rd50ldeErrurYI0.html

+SUBMOTO okay, I wanted too use the airbox but I could not mount the seat because the box was in the way :( so I dont know what i should do now :/ how did you mount your seat? :)

well, I was lucky on both bikes, the air box doesn't stick out on top, so I could lay the seat on without a problem. What kind of carbs do you have? if you have flat slide carbs, you should be fine as long as you re-jet it correctly. If you have CV carbs, that's a different story.

+SUBMOTO Okay, i will look it up :)

Ramon Santiago it'll be like playing beer pong blindfolded... but with a ton of luck, you might just hit the sweet spot :-p if you want pods, just put it on and then get her on a dyno, then you can re-jet after that

SUBMOTO yea it wouldn't hurt. honestly if I just slap it on and it helps, sweet. if not I'll go stock lol

You take the bike to a rolling road specialist, they do all the work for you for a fee, or you can do it through trial and error

if you have flat slide carbs and can get a pro to help you, you might be just fine.

is this it? www.ebay.com/itm/142006196620

+SUBMOTO yep thats it. A bit damaged but it the complete assembly sans the filter itself

Where do you live?

+SUBMOTO In the states

I'm not a pro builder either :-/ I wish I were though. Until then, I'll leave it to the pros

Copenhagen, Denmark :-)

+Steyreon Sometimes adjusting can be enough, but more times than not (especially when using pod filters or straight pipes), you will not be able to adjust it far enough, and will be forced to re-jet. Here is a PDF that explains the process and the need quite clearly. hope it helps :-) www.mikuni.com/pdf/hs40_manual.pdf just read the 'tuning manual' from page 2. It helped me a lot to understand the different 'phases' of carb mixture

+SUBMOTO woah thanks dude, very cool 😄 nice concept of driving while talking 👌

Yeah. I've gotten more proficient since this video, but only on a flat slide carb, and nowhere near enough to 'improve' on performance. I finally found a dude with a dyno that can tune. I hope He'll help me out, and teach me some tricks. I gave up on the CV's though. I couldn't find a mechanic that dared touch them with a ten foot pole

:-p

+SUBMOTO submoto smooth af xD

Jimmie Nilsson If you have a dyno, and you don't have CV carbs, then yes.

Luvin Itall did it on my single flat slide, no prob at all. just had to get it on a dyno. managed to ruin my engine though by jetting it wrong though without a dyno. but this GS is impossible. it's a CV carb, which is a whole science in itself. I just mounted the original air filter and sold the GS, now I only have the SR500

Hi how did u get your cb 250 to running probly with pods on I'm having trouble with mine

SneakyZeke 100% in agreement!

Sam Souissi this was filmed in Copenhagen, Denmark :-)

SUBMOTO awesome brother. Keep it up. I wanted to open my airbox but after watching ur vid I decided not to, I'm not after speed I'm after comfort and mpg. I'll keep my original Air filters. Ride safe

the only legit reason to do it on an old street bike is for looks (unless you are gonna race and it's about winning by microseconds and you have a hardcore mechanic at hand). I did it on my flat slide carb for looks on my newest bike because the previous owner threw out the air box. It's NOT faster or better in any way, but I got a mechanic to measure it with a dyno and even then it was a hassle. but it works now and looks good. But that's a one cylinder flatslide carb, the most simple construction out there. on a CV carb (like on the bike from.this video) you'd be shooting yourself in the foot by changing it.

Thanks for the advice bro. Hope we cross paths one day. If u r ever in Malaysia or Tunisia let me know.

1- Injection bikes need to be re-mapped, they don't just magically adjust. 2- The sound difference is neglegable. AirPods don't make an exhaust sound. You do you though. Good luck on your bike.

"If you're increasing airflow into the engine by installing pod air filters, this can significantly impact the air/fuel mixture and may require remapping the fuel injection system. The increased airflow can create a lean condition, meaning there's more air than the stock fuel mapping accounts for, potentially leading to poor performance and engine damage if not addressed. Remapping the fuel injection system after installing pod air filters allows for adjustments to the fuel delivery to ensure the engine receives the proper air/fuel mixture for optimal performance and reliability. It helps to prevent running too lean, which can cause overheating, detonation, and other issues." There are plenty of resources online that explain this. You don't have to take my word for it. Just look into it :-) I sure you will find something easy to understand online 😊

@@Substereomusicengine sound not exhaust, de have restricted laws about exhausts,and since I change the filter the bike rises the front wheel xd

I'm in Copenhagen Denmark at the moment :-)

SUBMOTO its clean and lot of people on cycle and no traffic , thats awesome place to live .

+Nirmal Agarwal it has its good sides, but also its bad sides

it cant be bad as india lol , 1.3 billion people with no plans of slowing down

I have yet to learn how to get any 'better' performance out of a pod filter. I have been trying for 8 months now. I'm sure I'll get there some day. If anything, I am sure I have lost power in the high revs

+Mike Brink yup, my experience exactly.

Except there no such thing as just slapping on a pair of pods. You will also gave to buy the jets. And that's if you can re-jet it yourself. Most people will also have to pay for a professional who can do it for them. I have gone through hell trying to do it myself. Also those 5$ pods are shite quality. I had to buy the corresponding (bigger volume) pod from K&N, and they don't come cheap. If you simply put on a pair of pods without re-jetting, you will run lean, and therefor hot, and in time you will ruin your engine. All of a sudden 80$ sounded like a good deal :-)

all of what you say is true, I have jetted holly carbs and can read plugs I plane to cover the cheep pods with foam, my 70 Honda CL450 is a work in progress, I can put larger jets in but I don't know how to deal with the needles, any way thanks for your response, good luck

+SUBMOTO Actually the CB/CL450/500T is one of the few bikes that very rarely needs a rejet when switching to carbs. You can literally slap on K&N's and just call it a day. But as far as I know, you'll want to rejet with any other bike.

+Amateur Chemist cool, I had no idea :-)

+Amateur Chemist I wonder how the physics behind that would work. Sound very interesting

You're absolutely right, but the pipes you mount also play a critical role, so it can still vary quite a bit. Also, my bike has those pesty CV Carbs which are near impossible to re-jet, and when you do get it right, even a slight side-wind will throw it off :-p

A 10% change will stop you burning a hole in the piston.

Hehe, yeah, I tried the ol' "oh me no speakeo your languageo" routine, but she just kept on comin'! Haha :-p

SUBMOTO yea I could see that :D was it a jehovas?

No idea :-p but she looked awesome! :-p

SUBMOTO you should have heard about those news... could have been a good laugh :D

Yeah, it's crazy :-p I'm in Denmark. Not only licenses, but also the price of bikes themselves (and cars) are ridiculously expensive. 180% in taxes over market price. So a 1000 dollar bike will cost you 2800 :-/ 1000 + 1800 tax

Gonna have to disappoint you there ;-)

I think it was like 36 bucks in Oklahoma :-p Cali's pretty cheap too. Prices here are are just outrageous. Same for car licenses. You'd think that makes people better drivers ...but you've seen my vids. No difference there :-p hehe

SUBMOTO lol

I'm sure there's an unspoken percentage of accidents that are due to stuff like this :-D The kind of thing statistics don't take into account hehe

We die trying to get a peek a little bit of that heaven.

Exactly. Seems like too many variables to make it worth it. I'm glad to be back on the stock filter, she's never run better :-)

SUBMOTO sweet way of giving up for the looks! what works goes the day, and too much messing give a shitload of hangovers!!!

Is it the air-fuel mixture being disturbed if I have a EFI(Electric Fuel Injection) system, since he talked about carburetors. Are Pod filter also causing those problems with EFI systems?

yeah. It's crazy. I think Finland has it worse that Denmark. and you'd think that would mean that a system like that would produce the best drivers in Europe ...but nope. you've seen the vids. they suck at driving, regardless :-p haha

Where i live all it takes is about $35 and a figure-8....unless you take the MSF course then its about $250 and a $15-$35 fee to get your licence. U.S.A!!!!

Thanks for your input Chad, although I'm right here. You can also just tell me 😀 Ok.. fair enough. But as I also said in the video, if you have a badass mechanic like yourself to help you then it's doable. Just like they do for racing. My point is based on speaking with my mechanics who, like yourself, are also very experimental and likewise have strong opinions. In regards to the CV carbs, what they explained is that the whole point with the invention of vacuum carbs was before the invention of fuel injection, where the idea was to mitigate the effects of varying air pressure as a result of altitude variation (like riding through mountains). For this reason the air box creates a micro-climate, which evens that out and allows for mountain riding a varying external climates. PLEASE do tell me if what they told me is wrong. I also said it's easier done on a flat slide. In fact my most recent bike has a flat slide (TM36) and a pod. That's how it came when I bought it. As a result, the engine had run too hot which expanded the cylinder and was burning oil. I had to have it bored out. So the previous owner mounted a pod, he simply looked at the plug colors (probably only on the idle stage color, since as you know, each stage will burn differently) and he effectively ruined the engine. I chose to keep the pod, but I had a team of mechanics to look at it, who had it on a Dyno three times. I have now ridden like this for about 5 years. There is NO performance enhancement (as documented by the Dyno sheet), and Everytime it rains, she sucks in water. It gets ridiculously dirty from city riding and affects the mixture as a result. Looks damned sexy though. I am considering getting an original filter, just because of the rain and dirt factor. So my point stands. - do it if you have a Dyno and mechs - do it if you have a show bike - do it to race - DON'T do it if you think you can determine mixture from plugs color - DON'T do it if you are a daily commuter. Not worth the headache - CV carbs have a micro-climate system, so using a pod kills that function. Like I said. Please correct me if you feel I am wrong. But please be polite. I'm right here. My name is Chris, and I am always open to good arguments.

well, there's nothing wrong with getting pods as long as you get the bike on a dyno and measure it properly. Just don't 'rule of thumb' it. Make sure to get specific readings, otherwise you might be looking at having to fix your engine

@@submoto sorry I just cant comprehend why you'd need to dyno a carburetor 4 stroke because you change a filter. I've been toying with dirt bikes for years and the fuel mix is one of the first things you adjust. I'm not trying to gain HP, nor do I care what the output is on paper.
