250r uni pod filter???

[westhall55]

i took the air box off my 250r and i was looking around for filters that clamp on the carb. i know k&n makes one thats 35mm inside diameter that would work. I would buy one of those but too much upkeep and cost. I was looking and it said something like uni pod air filter that looked like it bolted up to my 34mm carb,but it didnt specify it did. can anyone give me any info?thanks

-and will i have to run a bigger main jet with this also?
