Coolant loss - where ? Why ?

[Scholle]

In the worst case, it could of course also be due to a defective cylinder head gasket. To control that, you would have to do a compression test.

I looked at the pics again Georg and they are almost exactly what I experienced, spotting under and on the oil tank as well is the exhaust pipe.

Hello Rocketeers,

Roadster pisssed in the wind today.
Noticed coolant down the side and on the exhaust.
It only leaks when I take off and ride.
It never drips it onto floor.
Flushed and filled radiator a month ago.
Followed directions to the T.
Overflow bottle stayed full for weeks and now, it is empty.
When I ride, the bike leaks out coolant but only after it's warmed up and I
take off. Nothing drips while bike is sitting. No trace of coolant around overflow cap.
None near radiator cap and pictures shows the trail it takes when it leaks.
Should the overflow be full of coolant when bike is cold?
Why is it empty now? When I refilled radiator, it took 1 full jug (half gallon) of coolant and almost
half of another equaling about 3 quarters of a gallon to fill radiator and overflow which seems not near enough for radiator and overflow correct?
How much coolant should be in my bike?

Another way for checking if the headgasket is leaking or a tiny crack in the cylhead you can have a look into the oiltank.If the surface of the oil is creamy, coolant is also pressed inside the engine when running.My experience.
