    !992 Sl 650 Trouble!!!

    I have in number 1 cylinder ( I guess that is the one on the mag side) 105 PSI, 2 and 3 have 120 psi compression. When I run the machine for about 10 minutes it fouls plugs 2 and 3 and the cylinders spit out alot of water. The machine has a respectable amount of water in the bottom. I replaced all the head gaskets and have the same problem. Can water be coming in from the exaust manifold? When the machine quits 2 and 3 cylinder have a gray milky look to the plug when # 1 plug looks good. Can someone shed some light on this?

    Could it be possible that the water jackets in the case are cracked? That would allow water in it.

    where is a good place to start, should I be alarmed that the # 1 cylinder is about 10 psi less than the other two? Is that giving me a hint at where the water problem lies? I am very new at these skis!
