dont forget your fuel injector also has a ticking sound....so better check thoroughly.....my z800 at first i thought it was a ticking from the engine...but whne i looked it up it was just the sound from the fuel injector

the ticking sound from fuel injector is normal....dont worry bout it...before adjusting whatever the problem is..better look on the internet what is the problem....like i said before for me at first my z8 had a valve ticking problem...but when i search back i was actually the injector sound....
