January 21, 20215 yr Does your tappety noise sound sort of like a busy sewing machine or is it more of a tink-tink-tink with the pitch of a small ball peen hammer hitting a hard metal surface? Is it just noticeable and only at idle? Mine had the tink sound and so did the only other Beta 4t I got to listen to. I traced it to the cam chain tensioner. They have a very small spring. The sound was still there with a new tensioner so I went to a manual tensioner and it went away. When you look at the tensioner, the ratchet mechanism is made of hardened steel so I think it was designed to sort of bang away while the chain tries to flap around. I think it is normal and does not hurt anything but found it annoying. Probably the only reason you can hear it is that the rest of the engine and standard muffler is so very quiet.
