Gtx 185 2003

Is it possible that the cam chain fell off on startup, working perfectly then went to start and no go, Compression test revealed #1 Full comp #2 half and #3 no compression.
Any Ideas would be muchly appreciated.

Have a look at the spark plugs, dropped valve would be my initial guess but it's only a guess until you start tearing into it.

The 2004 to be early 2006 had hollow core exhaust valves. They are prone to drop a valve. I am not sure what they used in 2003.

That said, your compression is so poor that you are going to have to open the engine up.

Whatever it is, it is serious.
