It is not a fuel hose. All fuel hoses are new.

It seems that I have lost the picture of the hose. I think it is called a "crank case breather hose"

I have driven (without knowing it) almost 9000km with no clamps on that hose.

Ah, right. If it's badly split then it can cause the engine to run weak and it will dribble oil down the side of the gearbox and the coil housing. AFAICS the oil mist comes from the crankcase breather and should be sucked into the engine to be burned. It took me a long time to find out where the oil streak on my gearbox was coming from.

Ok, good to know. Bad hose is now on my naked K100, so it will be easy to spot if it starts to leak oil.

This lovely bike has found it's new owner. Goes to a good man, who might even put it to museumregistry when the time comes (vehicle has to be 30 years old).

Are you OK Tenox?
I have not yet sold any of my Ks and the thought does not thrill me.

Did you tell the new owner to sign up to the forum?

I did not. But the bike is still in my garage so I will tell when he collects it. And I'm not OK, but that is another story. And I still have that one K100.
