Not bad at all, helped me out 8 years later

So you kinda defeat the object of high flow air filters by blocking their intake.

What can I use exactly for the inside to create tunnel?

Here's the deal. Most stock air boxs are tuned for the bike. Understand this grasshopper. The intake valve closes. That moment or degrees. Stops the "charge" from entering the combustion chamber. That mixture backs up. That is why there is a tuned intake. All engines not motors, are pumps. It is all math. They pay a lot of money for the college boys to make the machines perform. Stop punching holes here and there. And because it is louder only means your sorry ass needs attention.

What size of pods did you use for your twin carburetor???

Them old Johnsons still run good!

Aug 2023 , did something similar on a 1985 Yamaha 750 Maxim XJ , previous owner destroyed air box only to it no run anymore, gave beautiful bike away, now my baby , It’s all about the air flow, siliconed the pod ribs progressively until she purrs great now, no jetting, turn back pilot screws 2 turns. It works🎉

I have a cb750 with pods. I cut a half inch out of the meeting rubber rim of pod and added the plastic tunnel with Pepsi bottle plastic. Absolutely F$$$$%! Fly's !! Ps Use crazy glue to keep them from collapsing (the plastic tunnels)

Its blocking the slide vent you need to shave the rubber from the inside

CV carbs miss the stock airbox Velocity stacks that help cv carbs operate right. So basically you put Velocity stacks inside your filters.

Please post a little more info or a full yt video. So many of us out here trying to do this. I still don't get it after watching your vid here... thx!!!

I switched to a pod filter and did the same thing with the plastic and still can't get it tuned right. Idle seems fine but everything above that it's stutters.

Really cool mod.

That was a waste of time and money since you didn't achievhe any horsepower yeah some trick

I know this is an old video but I can't help finding the humor how many people are interested in restricting airflow so they can run a performance oriented air filter on a lame ass cv carb. You can put a lighter spring in the cv piston for many applications. This reduces how much vacuum it takes to open the slide.

I’m glad I’m found someone that tried it because I figured there was a way to restrict those pods effectively. (EDIT) don’t do this. Save money. Buy stock airbox. Not worth the money wasted and potential damage to your engine. It’s better to do it right than have nothing at all.

Thanks!

Pellet gun?

Worked GREAT for me. Went from bogging at higher rpms and load to wide open free rev limiter thank you

Great video, very helpful, how did you determine the depth of the plastic sleeve and how much air to restrict? Your a smart man, thanks.

Love the bike! I'm doing a restore on one. Great tip to eliminate the air box. Thank you!

rev up your engines!

Yawn

I almost got divorced because of this video your tip almost costed me my marriage

Is that motor certified?

Incredible

Perfect explanation and video! thank you for sharing

Back when these pod filters first came out ..guys were wrapping tube socks around the filters and rubber banding them on ... Pretty much the same idea as your ...restrict them up ...

That's for the tip!!

I used tennis balls, thanks'🤣

HHHAHAHAHAHHA bloody idiot

Did this year's ago with insulating tape onna old GS trike running bandit carbs and crappy cheap pods,it ran pretty good but the tape looked crap..just doing a GSXR with bandit 12 motor and pods, fucking d a rejet and tuned but still not right...think standard jets and try this !

I got here by looking for "dual flange air pods for motorcycles" and your video is the first result. It's all about limiting air flow so the carbs receive just enough volume of it. So this is excactly what came to my mind earlier today! (except that I was thinking on wrapping some thin rags around the pods). Thank you for sharing!

What size are the pods?

Your a f#cking idiot

I think you just saved my Vulcan 500

amazing trick!! i hate my pesky difficult to remove tight squeezed standard airbox on my bandit1200 makes me so afraid of removing the carbs because of those..

$3.99 you can't be that 💪

Excellent ,for same performance with more space.

Silicon Carne! Good job!!! Make sure you oil them!

All you got to do is spray it with heavy duty silicon spray come in a can for 3dollars an you know the best part of it all you can spray it on any thing except plastic.it keeps it moist.

You know reason why boots get dry.......haha cause they get dry duh.

the engineers did a excellent job making the stock intake for cv carbs i have a 1982 yamaha 750 maxim. it runs perfect, pod filters suck and let dirt and water in the intake. color tune is the greatest way to get the bike tuned. and the boots are tricky to install but not really that tough

Getting rid of the airbox is win for me. The tunnel effect is the most important on CVKs. The tunnel length can be guided by inlet rubber from the airbox. I had to cut some rubber pn the pods so they don't block the vacuum inlet. Thanks for the tip Ben.

PRO TIP: With these cyclone style and uni foam filters make sure you cut out halfof the interior rim of the filter so you can rotate the filter giving clearance to any air-intake ports. (kidney shaped hole around the interior rim of the carb.) DO NOT USE WASHERS INSIDE THE FILTER. You will block the main air intake port causing surging while decelerating. DO: Simply drink a can of beer then cut the top and bottom off and cut it down the side. Trim it to fit around the filter all the way to the end and tape in place. If the engine boggs down when revving, trim the length of the beer can from the farthest end of the filter 1/2 inch at a time. This increases airflow. Once you find the sweet spot, trim the width of the can to fit snuggly inside the filter like this video illustrates. Go for a ride :) CREDENTIALS: jetted and pod'd my last 5 motorcycles using this method with excellent results!

Wow why would you buy pod filter, Realy bad ones at that, that restrict the pilot intakes and when it leans your carb out because it is flowing ,you restrict it instead of rejecting. Yes a little work, but once you do it and get it right, it's magic. All the riders out there that say Cv š can't be done sorry it's bullshit. Even if you do it like we did in the old days, by the seat of your pants it works, don't restrict your flow because your lazy

So you buy a more flowing air filter and instead of increasing the fuel flow so that it increases the performance, you reduce the flow of your air filter to keep it as if it was stock...

Putting restrictions in the filter to prevent having to re-jet defeats the entire point of a freer flowing filter. Carbs lean out when these filters are fitted as they don't give as much pressure drop, great for maximising airflow but the resulting higher pressure at the mouth of the carb means less fuel flows through the main jet.

thanks, I luv Honda, but this 1982 honda night hawk 650 stock air box design came straight from the depths of hell 🔥

Dude that's cool and all but visualization is better. Can you make a video on actually modifying one instead of a after is done ? Thanks
