crf intake system

I recently purchased an o4 crf150. I changed the pipe immediately to an fmf . We noticed a slight difference in power mostly noise. Today I put on a Pit boss air filter. I removed the existing air box and I have this small looking air filter. OK, well, dude the thing screams. I raised the needle one step up and did not touch the main jet. we just need to figure out a way to mount the mud guard. Next I would like to change the chain and sprocket to a 420 set up with 17 tooth front sprocket.
