Hello, My Z650 2019 makes this ticking noise while idle and rattling noise while i'm riding especially between 4000 - 5000 rpm. I'm a 100 percent sure it's the cam chain tensioner that needs to be adjusted. i went to the dealership 3 times and he told me this is normal and is fine and wont look at it. It annoys the hell out of me. I read about resetting the CCT but i don't know how to do that. i also read about manual cam chain tensioners but i can't find one for my bike. Are there any other riders that have this problem too? Does anyone here can give me some input?
