After the nonsense with the main fuse and petrol muppetry on the GFR a few weeks ago I took it for a short blast last week only to find a small pool of oil under it after parking up at home again for a few minutes.
It was pretty clean looking and finally traced it to the gearbox sprocket shaft oil seal. This was oozing gearbox oil because the sprocket nut had come loose! I changed the sprockets when I did the rear linkage bearings and I'm sure, though I reused the lock/tab washer I installed it correctly. It was still bent up next to the nut but the little tag that goes in the slot in the sprocket was flat. Perhaps I didn't locate it properly. Anyway, Uncle Bob had a new one and it is now reinstalled and the gearbox refilled, though it had actually lost very little oil. Lucky I noticed it then. A slight delay was caused by disturbing the connection for the neutral indicator light so I had to have the bottom fairing off again, but it's ready to roll again.
I might take it to the local VMCC meeting next month - it's only one year short of being eligible
