2004 650 V-Twin Compression Problems

Whats up Tech people, I need some input here. My mechanic and I are confused. I swamped my 650 V-Twin, however the water was never over the intake. It stalled in the water and we towed it out pulled plugs changed, changed oil. But My wheeler wont start. We have good spark. I changed my dynateck cdi, back to the stock one so see if that made a difference but nothing. We checked the compression in both cylinders and found that we have no compression. We then checked the valves and they are all ok. So we are thinking its in the rings and pistons, but we thought it to be a little odd that both cylinders went at the same time when the water never went through the intake. Just checking on the forums before we have it apart to make sure there isnt something we might be missing to check or try. Thanks Guys.

No compression may be the compression release. Are you getting fuel in the cylinders?

I'm pretty sure we are getting fuel If i hold my finger over the plug hole its damp when I try to turn it over. But if it was the compression release wouldn't it hold one of my valves open all the time?

This is wierd. Today my 04 650 vtwin messed up also. I was playing in some mud but never got water into my motor bc its snorkled. I think I think I blew a ring though. Good luck!

Anyone else have any ideas? Like I said my valves are good, I just can't see blowing both rings when I wasn't really revving that high of rpm's and water never went in through my intake

When you changed your oil, how did it look? Even a little bit of milky oil is hell on the Kawaski engines, as they are not very durable.

And why changed the oil if no water got into your intake? It sounds to me like you might be trying to reassure yourself.
