too lean after uni filter?

[lazar40]

Hey guys. Does it make sense that after I put on a uni filter with outerwear that Im runnin too lean? When I hit 3/4 to full throttle she bogs hard on a pwk 28mm keihin. The only thing I changed was that I went from a regular foam filter to a uni. I am ordering a 168 and a 170 main. I have a 165 main now. Just want sum opinions. Thanks.

A uni air filter is a much better flowing filter them stock. You will have to go to a bigger main. That in its self should tell you how good UNI is.

Thanks man. That is what I thought but its good to hear it from someone else.

Any improvement in air flow calls for larger jetting. Even running without the air box lid calls for larger jet.
