Les, From the geologists I have studied with (only a few here), I have not heard of any 'predictable cycles', and looking at the flow data from the volcanoes, I have not been able to figure out any 'cycle clock' that you can follow. Most geologists list cycles more as stages of a volcano, and in geologic time, all of the volcanoes on Hawaii Island & Haleakala on Maui are all still 'active', with the last known eruption on Haleakala figured around 1790.
Kilauea is resting precariously on the slope of Mauna Loa, and it is thought that it will eventually slump off down slope, but that is geologic time scale stuff. For a USGS note on the differences in the flows of the 2, check out:
