  We report Submillimeter Array (SMA) 1.3 mm high angular resolution
observations towards the four EXor type outbursting young stellar objects
(YSOs) VY Tau, V1118 Ori, V1143 Ori, and NY Ori. The data mostly show low dust
masses $M_{dust}$ in the associated circumstellar disks. Among the sources, NY
Ori possesses a relatively massive disk with $M_{dust} \sim 9 \times 10^{-4}$
$M_{\odot}$. V1118 Ori has a marginal detection equivalent to $M_{dust} \sim 6
\times 10^{-5}$ $M_{\odot}$. V1143 Ori has a non-detection also equivalent to
$M_{dust} < 6 \times 10^{-5}$ $M_{\odot}$. For the nearest source VY Tau, we
get a surprising non-detection which provides a stringent upper limit $M_{dust}
< 6 \times 10^{-6}$ $M_{\odot}$. We interpret our findings as suggesting that
the gas and dust reservoirs that feed the short duration, repetitive optical
outbursts seen in some EXors may be limited to the small scale, innermost
region of their circumstellar disks. This hot dust may have escaped our
detection limits. Follow-up, more sensitive millimeter observations are needed
to improve our understanding of the triggering mechanisms of EXor type
outbursts.
