Well, if you really want to test her barometer about the bike....take her out and get her really drunk on a Saturday afternoon and on the way home stop at the Harley dealer. The "truth serum" will tell you what to do.

FWIW, a friend of mine did this and marveled at his wife waking up Sunday morning with a horrible hangover to find him shining up the new RK she insisted he get while she was drunk at the dealer the afternoon before.
