Yep so, I now made over 500 mls with my MkII. After I accelerated the initially carefully gentle engine-friendly driving style and now gone often over the 75 mls/h, some oiling started at the end of the head. (Can also be due to the mighty Morgo pump?). Must pull the head at end of the driving season, making the usual decarbonizing and install the Otto Head Gasket Set ( $$$$$ :o ).

Hope that helps then against the oily boots.

Ouch!
A mate nearby had promised me 2 valve caps I needed for my Motosacoche. So I started my SQ4, but still looked in the oil tank and saw that was too little in there (see above). So properly refilled. Then driven to him all was good and works fine :lol: . When I got there, he stood in his yard, hearing me from afar. As I parked the motorcycle on the sidestand, the breather hose spilled about a pint of oil on his yard, which was very very embarrassing!
He made big eyes :shock: and immediately ran for a bowl and a rag.

Explanation: I misinterpreted the wet sumping and filled in too much oil!

It allways makes me wonder what it is why people are attracted to this lifeless Teutonic vehicle instead of a genuine oil incontinent beast from Albion :lol:
