Intake

[East London Geezer]

I have an 1150gs and noticed oil seeping down the outside of intake tube on the left hand side.

Any ideas what the problem is?

I recently replaced the engine output shaft seals and seem to recall that the engine breathes from between these two seals. Any connection?

Probably making its way out of the airbox after being overfilled at some point
