If you whip the chrome cover off, you can watch the valve rotate as you rev the bike. Depends on whether the 3 bolts come off ok. As has been said, lots of penetrating oil over several days is the way to do it, and pray! If you don't fancy risking it, you should be able to see the two cables moving if you've got a torch.
It will run like an utter dog if the valve is sticking though, either like a 400 under 5000 revs or like a 600 over 5000 revs, depending on whether its stuck open or closed. It'll bog down and generally be horrific to ride.
Love the black paintwork and black engine in that pic, though. That's rare! I've got a black one and they are the fastest colour. And classiest.
