I have to mate - you can't see the level in mine without doing it - although, as said above, getting it in the dark and shining a torch from the front of the fairing sometimes works. Less hassle just to whip the side panel off.I cant see any water level on mine do i need to take the side panel off
I run my bike until the fans come on before I check my oil level, (I was told to do it this way by my Aprilia dealer). I guess that way you make sure that any small amounts of water are evaporated so you get a true oil level reading.
