Right.
Firstly,it`s a tad unfair on everyone`s sense of goodwill to post a 'Help...trip in jeopardy' which makes everyone think you`ve suddenly encountered a last minute problem which may spoil or cancel a trip.
The reality is that you`ve been too lazy to investigate when you had plenty of time to make good a repair,and now the clock is ticking..........
Anyway,there`s a good chance that your clutch actuating pushrod piston is binding,especially as it gets warm.
It`s a piss easy job to check.....remove the clutch actuatator arm then pull out the pushrod and piston assembly and clean everything... including inside the clutch pushrod tunnel.... then lube it all up.
Clean and lube your clutch cable and lever pivots while you`re at it.
LATE EDIT.....Just seen that your profile says F650 so that advice won`t be valid if it`s your only bike.
However,if you dash out and buy a boxer,you`ll be able to sort the problem.
