Personally I wouldn't recommend pod filters, bad idea with CV carburetors, and jetting I'd go 2 washers on the main needles, and then maybe if needed one size on the main jets, don't forget to tune those pilot jets for best performance.
If needed I can explain further.

Okay first off your only adding new slip on right? Not a complete system? So going up 3 sizes is a little extreme, in any case, unless you have access to an exhaust gas analyzer. Okay the washer modification is common for the Ninjette, you will need 1 or 2 4mm washers, and you use them them as shims under the metering needles part # 16009 , just slide them on before you install them. That will usually be enough without having to do anything else, maybe try another washer if necessary, but 4 should be the maximum if I remember correctly. . http://faq.ninja250.org/wiki/Washers_for_carb_needles Now on to tuning the idle mixture screws, have you removed the caps yet? I'm not sure if the overseas market has them or not? http://faq.ninja250.org/wiki/Removin...re_screw_plugs Once you have access to the idle mixture screws, then follow my guide, Quote:
Now on to why pod filters are a no no Quote:

You can leave the carburetors installed and do the washer modification, but it's a little tricky. If you get something wrong, you'll be pulling the carburetors.
To be honest, once you get the hang of removing/installing carburetors, it's a lot easier to work on them off the bike, and on the bench. Don't forget you have the adjust/tune the idle mixture screws too, per my guide above. Quote:
