    It may of burnt a hole in the piston, the plug didn't blow for no reason, must been running lean, have you been adjusting the carb. or changing the ex. system this can cause the problem, good luck hope I'm wrong but I've seen it to many times, check the compression on the bad cylinder to see if its the same as the good one

    Hi,


    If its the same cylinder as the where the spark plug explode I think it could be one or more of the piston rings from that cylinder that's damaged.


    Greetings Puran.
