Mine did it a while back, it's been multiple weeks if not two months.
Symptom: very difficult to shift gears. At first you may not know why!
Why: idle RPM way high, normal is 1250-1300 and we are seeing 1800. So the wet clutch is engaged. So you are trying to shift gears while the engine is coupled to the differential through the wet clutch.
What I did to limp home on the trail: Turn the engine off, shift gears, only start the engine when it is in the gear you want to use to move the machine. Yes, three point turns suck.
What I did to fix it: never figured it out! All I did was put it in neutral and rev it up about five times. DO NOT try to put it in gear until the RPM's drop back to the normal idle speed of 1250-1300. Once I did that, it has not reoccurred and it has been 500 miles and plenty of hours since then.
