Sorry in advance for the long post, but I don't know what to do. The guy I ride with, we grew up together and we've been riding together since we were kids and I'm trying to help him out. He has a new 14 KTM Duke 690 and we need some advice. He bought it in March this year about 2 weeks after I got my FZ and it has been nothing but problems. He broke it in right, but it started burning oil at about 800 miles, and was leaking coolant. Took it to the dealer and they said it was normal for that engine to use oil. It was to the point he had to bring oil for a 200 mile trip where he could make it back home. Took it in to the dealer to get the oil changed and asked them about it again. They told him it was normal but this time the overfilled the oil so it was above the top of the sight glass. I guess they were hoping he wouldn't notice it and that by the time the next service came around it would still be full. Took it to a different dealer, had the engine rebuilt at 2500 miles. Started using oil again about 500 miles later, although not as much as last time, and they still haven't fixed the coolant leak. Around this time the neutral light also stopped working. Made it to almost 4k miles and took it to the original dealer. They call KTM and they send a new engine for it. 200 miles later, burning oil again and still leaking coolant. Local dealer is a joke, the dealer that built the engine the first time won't touch it now, and you can't get in touch with anyone at KTM. We don't really know where to go at this point. His brother also bought a new 690 enduro r at the same time, and it has had the same problems. I build engines for a living and I know this isn't how it's supposed to be. Just looking for some advice on where to turn.
