CAN'T FIND NEUTRAL WHEN HOT
K2-K6:
Are you completely confident the clutch isn't slipping, at all?
If it does, then it'll heat the clutch pack and prevent you fully opening the clutch when hot.
If it works when cold, it suggests the mechanical components of the gearbox are OK and wouldn't need looking at.
Most of these are very concise regarding clutch operation setup, can you post a picture of the engine end of clutch cable looking straight onto it? To see if we can spot anything.
StevieWonder:
Yes Julie, only completed some 750 miles since top end overhaul, but no idea what the total mileage is or if the clutch has ever been changed.
K2-K6, Haven't ever notice any clutch slip, not as smooth as it might be and range from first bite to fully engaged could be wider. Am yet to give it a handful of throttle or pass 5,000 revs. Attached photo shows clutch level, with handle bar lever untouched. Would have liked to see it more in a 7 o'clock position.
All comments appreciated.

K2-K6:
To me the lever is too far rotated anti-clockwise.
To set it, remove cable from arm, undo locknut, and then adjust screw until you can just feel it has no movement on the arm. This tells you that you've taken all of the clearance out of the clutch thrust mechanism. Now back the screw out slightly until you get 2 to 3 degrees of arm movement, this demonstrates you've now got running clearance.
Only now fit and adjust the clutch cable. The cable should have enough slack (just) in it to avoid you loosing the rotating play in the arm, with the spring able to hold the play in clockwise direction.
Then try it like that :)

Thanks K2-K6, I have quite recently set the clutch in a similar manner to how you described, by using the procedure in the Owners Manual. I will do again using your description and in the hope that I can get it closer to 7 o'clock.
Gave it a run out today, before any adjustment, only about 10-miles, with air temp much cooler than I usually ride it. Interestingly, selecting neutral was noticeably easier. :-\ :-\
Will update when I had a chance to make adjustments as you describe.
Regards
Steve

Just a thought Stevie Wonder.... If I remember correctly the handbook has an error in it in relation to the setting up. I think it says words along the lines of 'turn it in until it touches and then turn ½ a turn clockwise' or words to that effect. It should read 'turn it in until it touches and turn ANTI CLOCKWISE ½ a turn'. You may well have sussed this yourself but I thought I would mention it just in case.
