IF you want to keep the small wedge fairing on there, your options are pretty limited. Suecanada has one on her bike - she may chime in her at some point - unfortunately I cannot recall the model at this time..
Parabellum (parabellum.com) used to make a special unit specifically for the R65LS, but, that was decades ago, and they don't appear to list it anymore - but, possibly one of their "sport shield" models for BMW airheads might be adapated to fit.
