I know there are many posts but i was hoping to narrow things down a bit for my 2004 CRF250r. I live in PA Temp 70-100 deg. 0-1200'. I have a white brothers aluminum pro II,removed backfired screen, white bros filter, Hot cam, flowed head, powernow, and High comp piston. Im currently running a 42pj, 165mj, 5th clip on the needle with a 55 leak. I have a really bad bog off the bottom and the it seems to fall flat on top. I was hoping someone had some suggestions?

I feel like it should have more bottom end. the mid range is good but the it lacks a lil on top.

Any help would be great
