According to the workshop manual the correct tension for the sump plug is 40 to 50lb.ft.
(I would only go about half that.)
When I got my 1100 ten years ago there was a slight leak from the sump plug. I did an oil change and found the sump plug was only finger tight and the treads in the gearbox were shagged. I also discovered 3 fibre washers, one copper washer and lots of thread tape.
I removed the thread tape and the 3 fibre washers and found that the sump plug now went into the gearbox far enough to engage on the good threads, but only just!
So I got a new copper washer and picked trough my sump plug collection (not as impressive as Simon's collection) and found the plug that had the longest thread (every little bit helps).
I drilled the sump plug to lock wire it as added security.
It still has always leaked a tiny little bit so on the last oil change I used the Loctite thread sealant goo and the leaks are now cured.
My son acquired a 998 Clubby van for $20 a few years ago that had been a paddock basher, the RF corner of the gearbox had hit a rock or something that severely injured it- subsequently the `sump plug' was a lump of hardwood, judiciously bashed in by the PO..
It didn't leak a drop either!.
No it didn't stay that way, it got stripped and its gearset transplanted into a better casing for his Clubby..
