I'd second Darren here. Just go through all the connectors, clean them and treat them with ACF50 (hey, I've beaten RiffRaff to it there!).
While you're at it make sure your sidestand pivot is clean and greased so that the stand folds up properly. Some while back I let mine get a bit mucky and when I went over a bump, it was enough to jar it down a little but it was too stiff to fold itself back, and the sidestand switch then operated to cut the engine. A new return spring, pivot bolt, and some grease sorted it out.
