All, Thanks for the responses! I indeed replaced the tensioner AND the chain. To me, it does not sound like the sound is created outside the engine. My oil cooler mounts are steel and good. The exhaust flanges are tight, as I took them off to replace the cam chain and tensioner. Also, the sound frequency rises with the trottle/revs, which for me links it to the engine internals... Any other thoughts?

Hey all, After lurking here for a while, let's introduce myself: Martijn, 27, from the Netherlands. I own a V11 Sport Mandello Rosso since a year. Since a number of weeks, the bike has developed a strange metallic rattle from the engine under idle and load. Sometimes only when hot, but sometimes also when cold. It has been quiet while being hot recently again as well. Done so far in order to find the issue: - Adjust valves to 0.15mm and 0.20mm. The intake valves had VERY tight clearance, the exhoust was around 0.10mm. Sound, idle and low rev pickup improved significantly, rattle remained though. - Replaced cam chain and tensioner for the Stucci type with spring. Cold idle improved again, no change. Rattle remained. - A local dealer suspected a pushrod had a separated end. Checked all those last night, all fine. No excessive wear on valve ends and rockers. The bike runs and drives great. It has done 34.000km. Fresh 20W50 from Castrol. Edit; it is not the single plate clutch, as I replaced that one last year for a dual plate version. A video of the sound can be found here: https://vimeo.com/183857762 Guys and girls, I'm hopeless. What do you suspect and should I still drive it or not? Kind regards, Martijn
