Sounds lean! Take your plug out and if it is white then your not getting enough fuel. If you find that it is lean then pull out your main jet, pilot jet, and needle valve and clean them very good. Put it back together and do another plug test to see if anything changed. If not then you may need a rebuild kit so pull the carb off and tear it down for a thorough cleaning.

Your lean! Pull the jets and needle before you burn a valve or completely toast your topend.

You will need one size bigger pilot jet, raise the needle some and increase the main jet up to about 150............

Or, if it was running fine with your mods, but started doing this after sitting for a while, your carb is dirty - clean it.

Yeah that's why I suggested he clean it because of his first sentence when he said it's not running the same anymore. Meaning it used to run good. So I'm guessing his jetting is correct but just dirty. I just had the same issue happen to my buddy with his suzuki 400 4x4. It was popping on decel and topped out at about 35mph. It was just starving for fuel. Pulled it apart and the main was almost completely plugged with varnish.

He is a bit unclear but does mention of mods to his intake and exhaust which would cause his condition...........
