is this the bike with the stock exhaust? if so a 138 main is way to big. the foreman comes factory with a 130 main. I would try one size up on the main with the mods u have listed. I have everything u have plus an aftermarker exhaust and I am only using a oem 135 main.

hope this helps.

Are you getting good fire to the plug? Are you sure the carb is good and clean, nothing plugged up? Maybe check your timing to make sure it hasn't jump time. I am at a blank without looking at the bike.
