Water mixed with fuel will cause running problems under all conditions, not just over 4000rpms. It will cause stumble at idle, stumbling at 1000rpms, stumbling at 2000rpms, stumbling at 3000rpms, etc. This does not happen on the OP's bike, so rain water not an issue in this case. Could be fuel flow-volume issue or electronic and ignition-related.
