Ok so this should be in the air-head section but iv got a LC so it's here.
I was out on a ride today and one of the riders has an R1200R air-head. She said it tends to drink oil. Fair enough it's a few years old. But the reason given seems a bit far fetched but here it is.
An air head receives most of its cooling from the front because of air flow. Therefore the front of the cylinder expands less than the back when hot. So the cylinder forms a slight egg shape. This causes a loss of oil past the cylinder rings which remain round.
Iv never heard of this sort of thin before. When I had an air head it didn't use any oil at all.
So is this a know thing or a load of bo...x?
