R1 (2003) sump oil leak
Hey guys,
I've had a great couple of days on my bike engined mini, getting the engine frame tweaked to fit (it distorted when it was finish welded) and
fixing an overpulled clutch (classic R1 issue!). I had a brain out of gear moment when after getting the frame uber hot in order to tweak it, I
proceeded to rest my arm on it and have a tasty burn to show for it now! Anyway, I managed to get the engine back in and all wired and plumbed up
again, and she was sounding sweet, but I noticed a small and very slow oil leak from the middle of the sump. I had a look from underneath and
it's a small hole (2mm diameter) in the sump which from looking at the digital manual, appears to be the thin oil drain pipe outlet and I am
thinking it could be a duff O ring? Has anyone else experienced this on their R1 please? I only have to take the exhaust manifold off to remove the
sump in situ so if it is just the O ring, I think that could be the next step. Any help would be appreciated.
Cheers, Ben

Get 2x O rings for either side of the water tube.
Don't forget to lube them.

The hole is the leak off pipe from the waterpump. It's there so that should the water pump seal leak it doesn't leak water into the sump.
There should be an O ring on it. They have a habit of getting knicked as you put the sump on and leaking oil.
