He did say that, didn't he?
As darcane stated, if that's the case (smaller front/countershaft sprocket), it's not helping you get better MPG.
I have gone to a 1T larger front/countershaft sprocket, mostly for the 500 RPM drop it gave on the hwy and the smoother range it put the engine in at those speeds.
I would at least go back to a stock sprocket (15T) and maybe try a 16T - they aren't expensive.
