That's very worrying, it looks like it has been submerged in water for most of its life!
Is this the bike you took to the artic circle and Russia? I'm guessing if so it was subjected to some dire conditions?
Still no excuse for what is supposed to be an adventure bike!
Ive had a few extra vibes recently and wondered if the shaft was looked at on servicing. Presumably to look at its condition, you need to dismantle it? Would it be the same with the other end?

That looks like the PTO for a plough you'd find muck spreading her majesty's highway!!
