    Help in Identifying - 750SS Kawi - Hammer Marks on the Crank

    Anyone have any idea what could have caused these marks?

    Friend's 750SS - ran OK then overheated and fried #2 piston and cylinder.

    If it broke a chunk out of the piston then it could have gotten caught between the crank and the case. Take a look at the bottom case check for cracks.

    Thanks, Morris - looked and can't find any pieces - piston looks complete and skirts are fine - rings welded into lands, but nothing missing.

    Was told the marks are probably from when it was trued during a previous rebuild ....

    hell of a way to "true" a crank. Maybe truly f***ed up.

    Almost looks like it was dropped. Or was in a redneck truing vice and spun a little.
