Ok, i've got a couple of small holes that maybe some screws / bolts have come out of. One is on the left hand side (as you sit on the bike) of the engine/head, the other is on the right hand side (as you sit on the bike) on the sump.
The one in the sump looks like it once had a bolt, though it dosn't seem to be a problem - no oil is coming out. The one on the head - is this normal, is it there from when the head was cast?

here's the pics -

they are both as they should be.

the one on the head is a drain hole. there is a drilling between the two sparkplug holes leading to this hole, to drain any water that collects around the plugs.

no idea what the one in the oil pan is for.

Cheers Youngy, thank for taking a look.

Hi it's fer the fitting of an engine bashplate/sump guard as fitted to TDM's.
