For masses $< 2 M_{\\odot}$ we find dimensionless r-mode amplitudes in the range from about $1\\times 10^{-8}$ to $1.5\\times 10^{-6}$. For the accreting millisecond X-ray pulsar sources with known quiescent spin-down rates these limits suggest that $\\lesssim 1%$ of the observed rate can be due to an unstable r-mode.
