Do I have a clutch problem?

[-ralph-]

Pushed my XT600E (2002 4PT with 10,000 miles) out of the garage in first gear with the clutch lever pulled into the bar and noticed a problem

1. Engine stopped, in neutral, bike can be pushed freely.

2. Engine stopped, in first gear, clutch lever fully pulled in. Clutch is not disengaging and the bike is very difficult to push, with the occasional turn of the crack and piston.

3. Engine running, clutch seems to be operating perfectly. Bike can be pushed around in gear with the clutch disengaged no problem. The bike does not seem to be dragging the clutch or creeping forwards at all.

4. Stop the engine again, the problem returns. Same as 2 above

5. Go for a ride, come back, problem has disappeared.

6. Check bike again next day when it is cold, problem has still disappeared.

Does this indicate a clutch problem developing?

I am taking the bike from the UK to Portugal this summer and don't want to have clutch problems on the trip. Happy to replace the clutch before the trip as a preventative measure if necessary.
