Hi, I have the following problem, maybe some of you can shed some light on it Or experienced the same. My Duke is now at the dealer trying to locate the problem. A couple of months ago the engine started to make a ratling mechanical sound. The dealer said this is normal for the 790, at least it is known that more 790 engines have the same sound. Last week at the Zandvoort track (Duke is 2 years and 4 days old with 8400 km) in my second lap I heard a “poof“ sound and the engine went dead. The engine rotates when the starter button is applied but won’t start. Computer read out at the dealer indicates no electronic issue. They measured the under-pressure in the bottom part of the engine (not sure if this is the correct phrase for it) it read 8.4 and this Should be 11 they said, so something is leaking (loosing pressure)? Anyone knows what that means? Beside the usual sweating of a bit of oil and coolant (levels were never low) I had no issues at all. I’ll post an update when I have more information, if you have encountered the same then please share, thanks.
