air pods and jettting up

hello all, i have a question. i would like to put some air filter pods on my carbs and get ridof the air box. i'm told that to do that i need to 'jet up' my carbs. now is there some sort of formula i need to get the right jet/pods ratio or is just getting bigger jets good enough?
thanks

 

Before others start throwing comic insults at your plan. . .
Why exactly do you want to do this?
There is no actual performance gain to this mod.

 

Do a "search" for pods and you ought to get your fill of ranting 8O ! If not, there's a lot of raving and hot air going on over on the XJ CHAT board right now :roll: !!!

BTW as always, there's at least 3 sides to every story :wink:

 

i want to do it cuz i don't want my air box. and it seems like there would be more room to work on the bike too. i don't know. i'm still a fairly new cycle owner and i'm just wondering about stuff. i don't understand why this seems like a big deal?

 

Removing the Airbox and installing Air Pods makes it VERY Difficult to Fine Tune the Carburetors to match the Performance the Carbs can be Fine Tuned to when the Bike's Intake System is not altered.

Generally speaking, VERY FEW are satisfied with the OVERALL PERFORMANCE of the Bike after removing the Airbox and Installing Air Pods.

You MUST be prepared to do a good deal of EXPERIMENTATION to find results that may not be totally successful in terms of Mixtures and Performance through the Power Band.

The process of Tuning to Pods requires a good deal of experimentation.
The experimentation began in the Spring of 1980.
The successful results have not been discovered yet!

 

But some of us stubbornly keep trying....

 

COME ON FOLKS!! CAN I GET AN AMEN HERE!!!

ruiner,
You are correct it does make the carbs a lot easier to work on.. The thing is you will be working on it a lot more!!! Unless you have been tuning and building engines since you were 8 years old stick with your airbox and save yourself some money and a lot of time... :wink:
1-clean your carbs once and for good
2-inline fuel filter
3-buy a new air filter and keep it looking new
4-when tis time to put the bike away for the winterwinterize it
5-ride it like you stole it for years and years without working on it as much as you ride it.

If not mistaken, doesn't your scooter have pods :roll: ? How is it running???

yes skillet I do run the pod air filters and my bike runs like a raped ape 8O

I also have the advantage of working on high performace engines and learning from the people who build them. Mostly mud boggers and drags but the theorys hold true for almost all internal combustion engines.

Seriously not trying to be an ARSE here! How about sharing some of your experience with us. A lot of us work by "trial and error" (mostly the latter in my case ). Believe me, I could come up with questions 'till the cows come home :roll: ...

I am trying to restrict my pods atm, runs way too lean with pods..

 

if you put pods on you will need to rejet I. My exhaust was opened up and a K&N filter installed.Lucky for me a buddy of mine had nitrous oxide on his racing truck .He loaned me his dill bits I drilled out the pilot fuel jets and the main jets just about done tuning .I had to retrict the exhaust as much as I could. Stilled riding and reading the plugs a real PAIN if it aint broke dont fix it took me several dollars and several weeks.

 

I did m8, went up a few sizes. My problem was the pods i got are cheap and offer little filtering and restriction.
I have added both and have almost found the balance there.

At least now it, starts, revs, and is rich, which is better than lean.

I was looking with the colortune today and playing with the mixture, i found i will have to go down a size in pilot and at least drop my needle before playing with the main jet again.

ruiner- you waded into this one blindly, as you can see, the pod debate it a hotly debated topic with no shortage of 'you can't do it'er's.
Like me, you probably like form over function, that's why you chose to ride the classic XJ instead of another shitebox.
The only plastic left on my bike is the half guard behind the motor, i left the ugly airbox out and went ahead with my mods.

If you don't like a lot of trial and error and can't actually make objects that will need to be made then don't do it.

Performance = shorter lifespan
More air = more go
Upsetting the stock intake = rat type bike, rides like one, but fun.

 

I'd thought that to tune the carbs and thus maybe get more performance would give longer lifespan, but then again my experience with XJs are limited to only 4 weeks

Also a follow-up question, I remember reading somewhere here on the forums of a guy who proposed that his engine ran smoother after being left out in the rain for a few days.
Considering that the air filter is protected from the environment when inside the box, how does this compare to pods when they're fully exposed?

 

Am planing to be traveling too fast for the rain to stick to me :lol:

Even changing the exhaust to 4 into 1's and sticking pods on will change the characteristics of the motor, inducing premature wear- More air, more combustion, bigger stresses.
Tuning for performance and tuning a stock bike are two different things.

 

I did a lot of riding in the rain last year and I never had any problems when my pods got wet. Now they didn't get soaked by any means but I know the bike would run richer when it was wet out.

On a seperate note I took my bike out for a test ride yesterday
first real test and tune ride of the year. I had a slight stumble in the 5k to 6k range though. So I took and moved the needles down one notch and tonight I'll see if that took care of it. I put new filters on it this year so I know I'll have to do a little tinkering to get it set up just right. :wink:

seeya,
James
