is it worth getting rid of airbox and getting pod filter right off carb?

[thekingblaster]

I have a stock air box and I was wondering if it was better to get a pod filter of the carburetor

I have a trenga 30mm carb and a stock air box with k&n filter would it be better to get a uni of the carb and i race hard packed and somewhat dry tracks

word has it that a direct to carb filter causes air turbulance and jetting troubles at low to mid throttle , but at wide open for drag applications they seem to be the way to go.
some say a 4-6" velocity tube helps "straighten" the air and help tuning those lower circuts ?

Seems like a good idea but if ur looking for strickly power from that mod I dnt thnk there would be much if any

 

[blaster0187]

Awks def right tuning would be an issue I would asume a 30mm carb is shootin in a healthy motor

 

[thekingblaster]

So if i get a velocity tube that would put the pod filter right where the airbox would be it would help the tunning problems and would jetting be required

i could never run a pod filter, i go through to many mud holes

Any time you make a change in air flow in or out you should at least check your jetting.

A velocity tube is just a normal tube right?

hmm makes me want a velocity tube and filter but i would get it wayyy to muddy

Thats what I use for my 30mm OKO no throttle issues at all. hauls in every gear. Just look for a 2 inch pod it's usally like a 5 inch atc pod filter only I dont use a velocity tube I just clamp it onto the end of my carb with the hose clamp that comes with it. funny thing is it's cleaner than my box filter on my other one lol go figure. but my jetting is a 45 pilot an 150 main. with boysens PSR reeds and toomey pipe and it's right on the money for me....
IMHO K&N is for the desert rats and UNI is more of an adequet MX filter

 

[89blaster89]

do you actually gain power off of doing this? instead of the stock airbox setup? i would probally run the velocity tube up into the airbox for more height

 

[JBRoc01blaster]

It would seem so as the air doesn't have to travel so far to get to the carb, reeds, etc. Kind of like how a right bend has less bends in it then a lefty . . . I myself would never do it as your inviting water in, and you would have to clean the filter MUCH more often. I'm sure it wouldn't be too bad depending on riding style and terrain, but I'ma woods, sand, dirt/mud and water type of rider so the filter off the carb would be a nightmare for me.

not power exactly in my opinion it's throttle responce. but yep I took the entire plastic box off of mine, and it's surprisingly clean. but I usally avoid mud. bit of a clean freak when I ride for as long as I can help it.

I run my foam filter directly on the carb throat, it needs at least an extra size jet to put it there, but I feel that it is worth it.

Some folks have experienced jetting issues, I seldom do, Maybe it is because I have experience of years on my side.

The larger carbs can sometimes be a little difficult to tune, but I can usually overcome it by adjusting the fuel/oil ratio to compensate.

Warning a paper filter cannot be used on the throat due to fuel spit back.

 

[thekingblaster]

Look at this removable air.box the plastics sat.maier on them
Is this the new style of plastics maier is making

 

[Racer51]

looks different dosent it......... must be cause I dont think there's screws on the side and front are there??
