Breaking news...."Taiwanese biker keeps helmet on as a safety precaution against escaping coolant"

My thoughts on this issue are thus. The coolant isn't leaking from overflow, as there is no sign of chalky deposits inside the fairing or on the engine or resorvoir. Even with expansion, when on the minimum mark, the bottle could not possibly overflow.
It's not ending up in the crankcase because the oil isn't foaming.
The only possible explanation is that it is being combusted via a faulty gasket or something similar. It would explain these bikes looking like a steam train when the start in the morning.
My intake valves had a brown black deposit in the crown when they were replaced which looks like burnt coolant to me
I've seen trucks do similar with faulty head gaskets.

Would be good to know what it actually is. If it was coming into the intake valves wouldn't you see smoke coming from the exhaust though?

I suppose maybe not if it's small enough amount.

rockdog32, unfortunately, I think you are on to something there.  If that is the case, it is going to be an expensive recall for BMW!

Is there a good legit BMW place to check posted recalls? Or do we have to rely on our dealers being worth a shite and letting us know?

I just had this translated from a Taiwanese mate.
He said "Bmw is doing a recall  something with the coolen leaked leads to stall"

This may be the answer to both issues people are having.

Here is the valves removed from my bike.
I just showed a mechanic and he said they look like they are from an engine not serviced regularly. These came out of my bike at 4,000 klms. They look like they are covered in non combustible stuff. I've seen engines where the coolant is leaking into combustion chambers and this looks very similar.
