Hi guys,
I'm new here, I've posted in the intro section. Got myself a 98 FZS600 with 16.5k on the clock. Got it late January and have since put over 2k miles on it myself. I've noticed since Monday that once I get above 4.5k RPM I get the telltale clacking sound. Having checked about it seems they can suffer sticky timing chain tensioner. So pulled the carbs, took the tensioner out serviced it and replaced. It seemed that the tensioner was fully extended (took the bolt off the back before removing to check) put it back together and still the same. So pulled the valve cover to check valve clearances. So first question what's in spec for the valves please? Also when the valve cover was off timing chain felt nice and tight but it didn't seem to sit all the way down on the cam sprockets. I could see light between the teeth. Is that normal for the FZS? My experience with DOHC engines s limited and the once I've seen, the timing chain sat right down on the teeth and no light was visible through them
Hope that all makes sense and sorry for the long post
Cheers
Ian
