Just changing a jet won't give you any performance gains. The size of the jet needs to fit the application it is placed in. If the application calls for a leaner jet, the bike will run better with a smaller sized jet. The opposite is true, if the bike needs more gas, than you need to put in a larger jet.

ditto what vegas said. The more gas you put in the cumbustion chamber doesn't make your bike faster. The perfect air/fuel mixture will make your bike faster.
