Oil leak

When I got back from yesterday’s ride I noticed some oil on my sidestand, on closer inspection there was oil underneath the drive chain side of my bike.
Tonight I removed the sprocket cover and had a poke about and noticed the sprocket was loose, well I have done about 500 miles since putting her together so I suppose something has to fall off !
The tab washer had lost its tab and the nut had come loose probably a full turn. I assume this then allows oil to leak past the ‘O’ ring down the shaft and out onto my clean undercarriage.
Hacksaw a new tab and flog it up ( to the prescribed torque of course, if there is one ? )
Glad I didn’t go for a ride today, weather was beautiful but work still keeps getting in the way. Suppose the moral of the story is ‘ you can never do too much maintenance or fiddling in the shed.’

As I pushed the kH out of the garage, I noticed an oily tyre mark on the drive.

Out with the cloths trying to minimise the contamination.

First suspect, gearbox. Nope all good.

Second culprit the-oil pump, nope again.

Glanced at oil window and no oil, all on garage floor.

Oil pipe had gone brittle and fractured.

Could have been a lot worse.
