1971 Laverda SF Teardown
This page documents the teardown of the top end of my 1971 Laverda 750SF after I burned a hole in the right piston during some enthusiastic riding.

This is an original standard size Mondial piston, so it gave good service for 50 years.

It seems unlikely that the cam chain tensioner was damaged when the piston burned through. More likely the failure of the tensioner contributed, maybe directly, to the piston failure.
