I am in the process of getting my 2005 EG yz144 jetted properly and need some help. Went on my second ride Sunday and could not be happier with the engine. I am running FMF fatty, Turbine core2, V-force3, with Eric Gore ported 144. When I had the engine done, I was instructed by Eric to go up one on everything. I also was instructed by somebody what had this done to start with a 450 main jet. Right now I am running the stock 40 pj, 06-07 needle in the 3rd clip, and a 450 main. The bike runs clean in all throttle possisons. There is not a stumble or bogs anywhere, but it is smoking a good bit and there is a lot of "spooge". I think I need to go one leaner on the pilot, raise the clip one, and go to a 440 main. I am going leaner than stock on the needle and pilot. I am just looking for some input from others that have had done the 144, and got their jetting correct. I am mainly a woods rider so it is more important for me to get the low and mid clean, and have the main be just slightly rich for protection . Thanks in advance.
