    what cylinder is this from? number 1,2 or 3

    there look sliek metal fragments on the edge of the top lan of the piston. I wanna say the piston also looks like it got hot and squeaked the cylinder too.
    since it is rough all around the edges, it also looks like detonation took place after the piston got hot also.
    The top of that piston definitely got hot and sandwiched that ring in place
    I still see marks where it looks like metal fragments look liek they dented the piston just like the top lan shows.

    Is there oil injection or premix?
    Was there a loss of lubrication?

    * What do the other two pistons look like?
