I'll hazard a guess and say your headgasket is buggered .

sounds like you got an airlock in your cooling system somehow which has caused the engine to overheat, boil over and pop the head gasket.

DONT ride your bike but DO get it to a garage to be fixed.

I've heard of a lot of head gaskets blowing on those engines but a rebuild at 9K sounds like bollocks to me, that's approaching Group B rally engine reliability!! Still swings and roundabouts, very high compression engines do get knackered quick, but they're more pokey, so they get ragged hard, so they break...

The 'adventure' range engines have been detuned a little I think, which should help. I wouldn't take a KTM on a big trip, and I ride Ducati-powered bikes (air-cooled, and once you have got your head around the valves and rebuilt the electrics the rest of the Ducati engines are pretty bullet-proof, I know someone who put 150,000 kms on a 750, rebuilt it with new rings seals and gaskets and compression was back to the factory setting!!). I wouldn't fancy trying to replace a head gasket in the middle of nowhere....

just a new gasket will be fine. the engines on the 640's are reliable as. You need a major service every 9k, not new engine rebuild!!
