the later 250 , 71 / 72 ??? had a 2.8 liters engine . you need to be able to tell if your engine noise is above head gasket or below [ loose piston or ??? ] head noise cause by rocker arms , cam , or just a valve cover too tight .
1972 250c Engine noise
Just purchased a 1972 250c, overall good shape, however engine makes a knocking sound. The previous owner said that a head job was done (doubt it), but could it be possible that the job was done incorrectly? Also, what could be the most probable cause for an engine to knock?
If so, is this particular engine hard to rebuilt?
