  1. My YZ is awsome but I have black drool comming out of my exhaust pipe. My sparkplug is black and wet. I know it's running too rich but I'm not sure which jet to change first. My bike is totally stock, (stock pipe and jetting). I changed the clip to the top groove position on my needle jet but it only seemed to run leaner with less power and the black drool was still there. When it was cooler out in october it pinged and did not run good. I'm thinking of going back to the 2nd. groove on the needle jet and changing the pilot jet and the main jet one size smaller. Can anyone help me that has struggled with the same problem? I would appreciate any help. Thanks in advance.
