Not an expert at all but that is bent.Do you have a good engineering workshop near who could check and maybe straighten it ?

Unfortunately no.

Already bought from a Spanish supplier, hope to get the new parts as soon as possible. Bought new pushrod , adjuster and special spring spacer. Fingers crossed.

I hope that solves it too !

Sorry, But is there any update on this? I am having the exact same issue, I Adjusted the valves multiple times, but the clacking sound is still there.

Unfortunately no. Sold the bike last Saturday.

Well , after sometime , the noise still there , so it was needed some deeper dig .

Noticed that my intake valve lash was getting out of spec , after 4 attempts (0.13 mm) , always getting alot of lash after some kms .

Took my push rods out and check it for some bending ...

uploaded this video ( sorry my english , not my native language) .

Need some expert thoughts.

The tip ( tappet side ) is swinging , and have some slight marks (scratches) along the push rod.

Can anyone get this video to load ?
Also, the cam wasn’t destroying itself was it ?

Unfortunately it was deleted and I don't have them anymore. But you can do it by yourself,just grab a mirror and take the part to slide on it. Any bend will be noticed by the sound it makes.
