I did change the needle to an NECW, if that isn't enough to cure the fatness I'll drop the main to 172.5..........not in the forest though

Don't confuse your carburetor circuits.
Most of what riders term as "rich or fat" characteristics are a result of the jet needle's part of the circuit.
The jet needle controls the transition from low throttle setting to mid-range.
The main jet doesn't have much effect until you are at 3/8 throttle turn, and doesn't come into it's real area of control until 1/2 throttle.
If you are still "fat" with the NECW, then I would suggest raising the needle clip one groove to see the effect.
