It could be as simple as something stuck underneath the shifting pawl inside the right engine cover. Just pull off the complete right cover, (not just the small clutch cover) and take alook. Hope it's something simple! Maniac

my advice,

avoid running the bike until you figure this out, it's hell when the gearboxes on these fail. i'd get the clutch cover off and have a look around, keep fiddling but you may have to go deeper

Taking off the Clutch cover will not expose the shift mechanism, so it is pointless. It's all on the other side.

sorry krannie,

i realize there is nothing on that side, just got confused when typing. what i meant to suggest is to get in behind the cover on the flywheel/generator side, and look at the mechanism on the other end of the gear selector shaft. you're absolutely right Krannie, I just used the wrong words.
good luck with it.
