Maybe one of the eccentrics was a bit loose and opened up some. That would give you a nice clatter in the top of the engine.
I'd go around and check all my valve clearances before I did anything else.

well ... that was the reason, the valve adj. on the rocker was lose I re-gapped the valves and started the engine ... it was all smooth. seems like at the high RPM the rotating adj. on the rocker turned to protect the valve from being bent. anyway ... its done now ... am happy that nothing much happend in the engine. ..................... thanks guys ur da best![]()
