I know I have asked this question many times about jetting. I have a 04 400ex with an HMF full system and I am running a UNI air filter with the lid ON. I got my jetting pretty close, but i still dont think it is correct. I am running a 152 main and a 42 pilot currently. When i pull the plug it is black and a little wet looking. I am not very experienced with 4 strokes. Can someone tell me how to get my jetting perfect.
