how do you figure you're flowing too much water? is it bogging, if it is and you're out of adjustment and don't want to change jets, you could up the meth to water ratio, the engine will take more kindly to meth flooding than water flooding.
That said, even with a .9 and 1mm jet I've never really experienced any sort of bogging.

no its not bogging, but the recommendation is 20% water/meth to fuel ratio...
