Higher flowing air filters, more fuel?

So on my CB200 Ive finally decided to replace the air filters. The ones on it are the dead old paper ones. Ive read how to get rid of those and how to add the UNI filter material in place of the paper.

I hear that Ill most likely need more fuel to match the higher air flow.
As a carb noob, what is the best way to do this and outside of checking the plugs, is there a good way to know when Ive got the fueling about right?

Thanks for answering what I know is probably an elementary question for a lot of you. :)
 
Aside from running it on a dyno and hooking up a fuel/air sensor, the best way is to do a plug chop. Does the CB200 run CV carbs?

Im not sure on the CV question.
I suppose the answer to that affects your answer on how to increase fueling?

It has the stock Keihin carbs which I believe someone said are CV.
 
Actually, it pertains on how to do the plug chop. The process for CV carbs differs from those where the throttle cable is connected directly to the slide(s).
 
Trial and error.
You do have a manual right?
and more then one set of jets to try?
and know how to tune a carb or have a friend that does?
 
My best advice would be to find a Cb200 build here that used the same filters. Then try to find out what jets they went with. But of course, you're results will vary.........

Thanks. That would be the best option I think. Maybe someone will chime in here that did this. Unlikely, I know.
 
Way to many variables for someone to just say "use these jets"
maybe you will just need to pay someone to do it right.
Either way though you need a manual and need to get a few jets.
