Thanks for the advice and posts to my original post.
Getting to know the bike a little better now and completed the following jobs
New gear box oil - Motul 5100 10w 40
Drain plug seems new and substantial
New Iridien plug
New front wheel bearings
New front brake pads
Drained old fuel and new added
Removed middle box and ground sharp casing corner off
Drive chain removed, clened and gresed
Clutch and brake lever end play adjusted
Air filter cleaned and lightly oiled but I am going to fit a new one as soon as I can get one.

Bike certainly starts easily.
