Hello again,
Long time it took - been a bit lazy and (excuses)  the weather has not really been perfect for driving...
Anyway, got the bike on the road the engine well cleaned, oil changed etc.
Found the leak!
The oil comes from the starter motor assy! elieve it or not!
After only 100km it was clear. Everywhere else it was nice and dry but underneath the startermotor very wet!

Is this unusual or common!
Any ideas how hard this may be to fix?

Thanks
Pauli

Now it is dry, no leaks!
I'm happy but this is also most embarrasing.
Guess what!
It must have happened at some point last summer when I changed the oil! The O-ring on the oil cap must have fallen off and I didn't notice! Finally I came to thing of this as an alternative for the oil leak cause!

In any case - Thanks for the help yyou guys have provided!
Pauli
