Usually other then the windshield (pledge), and the headlight when weird shapes are noticeable at night, about every six months. Or rain. Or on my trip the last couple of days, enough dew on it for a good wipe down.
I usually put 2,000 miles+ a month on mine. She's going to be dirty, and being grey, it doesn't show much.
Funny.... FWIW, Harleys, since the the Evo, now the TC engine, no longer leak oil. No more unlike metal make up of engine parts, heating and cooling at different rates. Harley does make some of the best MC cleaning products on the market; all that chrome, you know. The bug remover spray is AWESOME. Doesn't affect paint plastic or Lexan, either.
