does it freely move? or does it still have a bit of 'engagement' feel (resitance)
if the former, the problem may be the shifter shaft slipping out of place due to a missing C-clip (common on bikes, not sure about KR)
If the later you may need to pull either the clutch cover, or split the cases

dunno what it could be, but pull off the clutch cover and see if you can rotate the shift selector drum to get it into neutral.
if manually shifting gears via rotating the drums doesnt help you may need to open up the gear box.
Does the KR have a cassette box or do you need to split the cases to get to it?

I think it just unbolts and slides out the sprocket side so it could be worse i guess
