Scooter Cold Air Intake Fail.Dont Do This!!!

[@antoniskonstantakis5474]

And you are correct,,,the stock air filter works better with the jet set up on your scooter.... but if you want to replace it with an after market cone filter you need to feed the carb more gas so you have to play around with the different jet set up and not with the air/fuel like some people write on there comments .....air/fuel adjustment is only for adjusting the idol on low rpm

[@AZWDRDUB]

Idol idle up your engine this is a homonym

[@kentbarger6974]

You have to readjust your air fuel mixture on the carburetor because there's less restriction on air

[@larryhullinger4141]

[@georgebeard2337]

need to tune carb and the transmission. carb: Needs more fuel (richer than stock to compensate for more air) Transmission: need to be set to Variate at a higher rpm

[@AUDIO2AUTO]

You have to up jet the carb if you increase the air supply. Really you can just take out the piece inside the stock air filter too but you still have to increase the jets size or lower the clip on the carb needle.

[@jhunbugg1]

I agree on this! And it's all about tuning!

[@gregatron4528]

I just tried this, I went from a 107 jet to a 115 and it bogged at 1/4 throttle, so I went down to a 110 jet, still some hiccups at Wide Open Throttle .. I dont know what else to do, perhaps swap the pilot jet out from a 35 [I believe] to a 38? Thinking about just going back to the stock air box if its gonna be this much of a pain.

[@madhatterentmt6146]

@@gregatron4528 did you just swap or go back to stock box im in this same situation

[@curitosikls8653]

You need to rejet the carburetor after adding a new air filter or else the engine air fuel ratio isn't balanced, simply just buy some carburetor jets with bigger holes in them. If you had installed new carb jets with that larger air filter it would have actually increased your engine performance because you are adding more gasoline to go with the extra air passing through the carburetor venturi.

[@JarretLaMark]

Wouldn't a simple air/fuel ratio adjustment be the next thing to do after removing the OEM air box with a cone filter? Before going through a rejet? Especially if the stock 150cc engine isn't bored out.

[@irocss85]

@JEFF-QUICK is all part of the game. Same for my pitbike. Gotta remove the carb to rejet.

[@drrd4062]

Put a $75 after market exhaust system. Change main jet to 95, idle to 35. Top end to 80 cc, cam to a7. Pod air filter. You play with the clutches. I got 8mph more. No more pushing up hill.

[@cyberjack]

you can just remove the hose from the air filter then put the "new" filter on end of pipe then you don't have to worry about the crack breather pipe as its already fitted to original pipe

[@alexwatt3804]

I’ve just tried to do this on a factory carb, it won’t work unless you have an aftermarket carb with bigger jets, putting the filter on gives it more air so you need to give it more fuel, factory carbs don’t have the right jets to adjust. Ultimately you need a new aftermarket carb and then tune it.

[@irocss85]

Nah you can replace the keys in a stock carb and tune the air fuel ratio screw. But you'll need to UNtamperproof the carb to acess those things. You tube videos to teach you how to do that.

[@wildwilco]

well what you are doing is de-restricting your original air filter, because the original can only move so much air, because it has a bit of resistance. if you put on the ''power filter'' (is what they are sometimes called) you will LEAN the mixture because you are giving the carb way more air, and still the same amount of fuel. so what you should do is increase the main jet size by alot, and lower the roller weights in the variator to really notice the performance boost. but this is very tricky to get right, and the tuning can take days or even weeks.

[@dadlifegarage2292]

Filter works fine you just didn't tune it. Now your attempting a bbk?

[@vannyo6913]

The worst place for filter. All dust is there. High flow filters suck. They let a lot of trash through.

[@ianelliott3914]

I've got a uni foam filter on my 139qmb with upjettted carb 50mm bbk and larger head and a9 cam and runs great also best to fit bigger battery as I noticed the bbk has so much more compression the standard battery does not cope well

[@BrokeShooterCo.]

If you definitely feel like you have less performance then you’re definitely doing something wrong because every scooter will take a count filter you just have to tune it right and the current filter will allow the engine to breathe which in turn will make your bike faster I’ve had a lot of scooters that didn’t want to take a count filter unless you do some detailed tuning

[@Quarzrt]

And what is the detailed tuning and how to do it if it doesnt work i have a aprilia rs4 50 and i want to change my original filter to a cone ond

[@BrokeShooterCo.]

It will work with the air filter bro you just have to return the carb mine gave me the same problems when I first tried to put it on with the factory carb even putting a bigger carburetor on it so I took the air filter off bought a 24 mm nibbi. Carburetor to go with my navy cone filter and everything is running great now the bike really opened up I can do 0 to 50 in about five or six seconds with the hundred cc bore. And Palini variator clutch

[@albishahini3192]

wich is the best filter

[@steve8264]

High flow air filters do work if you got your carburetor adjusted right and the jetting could been a little bit too lean but they do work

[@michaelhightower8160]

🤨😳🤔Well it would have worked for you .But there is two air hoses that was hooked up to your factory air box that needed to have an filter on them to.🤨See that they were hooked up to the factory air box.

[@pomidorpl4631]

Because stock airbox have restriction in flow so with filter with almost no restriction AFR is lean to get it richer you must change main jet in carb to get it richer

[@csb772]

That was the sound of power son. A engine that can breathe will put out more power and will always be louder. Its the air flow you hear not the exhaust.

[@failblazer2004]

Induction roar sounds cool better than exhaust

[@irocss85]

Exactly what I was thinking. You can literally hear the air sticking into the engine. That is a huge factor for the factory air box. Reduce noise, keep the air dry, and limit the air to a specific meter about of flow. If they can relate how much airflow goes in, they can set up the carbs all the same to make it easy on them. Repeatable results. Not meant to maximize performance.

[@chrismartin6427]

The simple fact is if you introduce more air the bike needs more fuel and only giving the bike more air will mean the bike is running lean and we'll probably also bogged down and cut out under full Throttle

[@lyricmakris7610]

I got one off scooter tuning a foam one never go cheap

[@jamiediseker9232]

I'm trying to drain my Carburetor chamber on my blaze Wolf. And then the air filter seal is broken. How do I bypass that cold start and choke?

[@Kozycorgi]

Hey Josh, not sure if you've upgraded to a new carb on this scooter, but to get the cone air intake to perform better you should consider adjusting the fuel/air ratio screw on the carburetor to give the engine more fuel. The new intake may be causing the engine to run "lean" since it's supplying the engine with more air, decreasing the fuel to air ratio.

[@x_a7madoov210]

Gabe Gifford . I connected a performance air filter today . but my moped was so bad in acceleration and low speed with very high sound . how to adjust it . there are two screws . i have a honda 50cc .

[@wildwilco]

the screw that is directly underneath the throttle cable, will be your idle screw. dont touch it unless you want to idle higher. the other screw is your air/fuel mixture. turn left for more air, turn right for less air.

[@Quarzrt]

@@wildwilco where do you dinf the air intake screw

[@Quarzrt]

And how do you do that

[@jeffmee763]

Now you know why you should put a bigger jet in the carb.

[@gregatron4528]

Oh wow thanks for providing this video even tho it failed. Some of us need to see what happens and what we can do about it.. Glad I ordered jets when I ordered a new air filter. Reading the comments suggests new jets I see. I cannot turn up the idle screw it is blocked off, and would need to be drilled to get to it.. so I wont mess with that if I dont need to. Thd only reason I took the stock air box out was I bought that Ankle Biter CVT Cover and now my stock filter doesn't line up to the bolts. I can update anyone interested in what number jet I went up to. Also I live on the far east coast [elevation seems to matter too I believe]. Post a reply if you would like to know what I did. Have a great day n safe riding out there!

[@tdoja651]

Gregory Megatron What size scoot engine do you have? Then, what kind/size filter? Plus which number did you end up with for the jets?

[@scootersonlyrepair6773]

You have to rejet and get an aftermarket exhaust to go with it. You can't just slap a filter on and call it done

[@Nandothehobo]

what size socket do you need to take off the stock air filter

Will probably be a 10mm, this is the usual average.

[@999benhonda]

You can't add a bunch more air without adding more fuel. You have to put a larger jet in the carb to compensate for the increased air flow.

[@Tomijus]

@QUICK-STAR take off the carb, and then the carb bowl

[@MrBerenguer67]

You need up jet 2 numbers up

[@jamesroberts3041]

Just like that one said in the comments u need to rejet it man

Bro if you go up 3 size on pilot jet and 10 percent on main jet you want have that problem

You cant open the air intake up without re jetting the carburetor. Or you will have the problems you are having.

Cycle the air hose back through your air filter that’s why it didn’t work for you
