The quiescent periodic photometric modulations of two low-inclinationcataclysmic variables observed in Kepler K2 Campaigns 0 and 1, KZ Gem and TWVir, are investigated. A phase-correcting method was successfully used todetect the orbital modulations of KZ Gem and TW Vir and improve their orbitalperiods. The light curve morphologies of both CVs were further analyzed bydefining flux ratios and creating colormaps. KZ Gem shows ellipsoidalmodulations with an orbital period of 0.22242(1) day, twice the period listedin the updated RK catalogue (Edition 7.24). With this newly determined period,KZ Gem is no longer a CV in the period gap, but a long-period CV. A part of thequiescent light curve of TW Vir that had the highest stability was used todeduce its improved orbital period of 0.182682(3) day. The flat patterns shownin the colormaps of the flux ratios for KZ Gem demonstrate the stability oftheir orbital modulations, while TW Vir show variable orbital modulationsduring the K2 datasets. In TW Vir, the single versus double-peaked nature ofthe quiescent orbital variations before and after superoutburst may be relatedto the effect of the superoutburst on the accretion disk.
