  KIC 7341653 is one of several late-type M dwarfs observed in the main mission
of Kepler with peculiar infrared colors placing them in the domain of suspected
young stellar objects (YSO). It is likely associated with a powerful X-ray
emitter with X-ray flares. Kepler light curves reveal two distinct types of
activity: frequent flares lasting from less than 30 min to a few hours and a
periodic variability with a period of 0.5463441(7) d. The largest flare
detected increased the flux in the Kepler passband by a factor of 2.8 and
released an estimated 4$\times10^{34}$ erg of energy in the Kepler band.
Segmented periodogram analysis reveals that the amplitude of the periodic
variation was subject to secular changes, dropping from peak values around 20
ppt to below 5 ppt toward the end of the mission, while the phase varied
periodically with an amplitude of 0.15 radians and period 362(3) d. Two
possible interpretations of the phase periodicity are discussed: a migrating
long-lived photospheric spot and a Doppler frequency shift generated by a
solar-mass faint companion, such as a white dwarf.
