My Z is making a loud ticking noise that sounds like it is coming from the top end. I have had it in the shop and every thing is in specs. I have been told that it is probaly the timing chain tensioner so I took it in to the shop and switched it out with, no availe. My adjuster is all the way out but the guide behind it is rubber so I dont know how it could be making that much noise. Just wandering if anyone else has had this problem on a stock 04 Z400. Or how to fix the noise.
