Got your PM. Sounds loud to me. Does it go away when you rev it and get worse on deceleration? See how many clicks are left on the timing chain tensioner. If you donít have a manual, you can search how to check it. Basically, remove the center bolt and spring, then remove the tensioner. Count the number of teeth left until fully extended. If there arenít any left, itís time for a new chain.
