    powervalve question

    I have no compression on the rear cylinder and the other two are low. This happened in just a few minutes of riding. After looking at the engine I noticed that the powervalve cable was frayed in two on the wheel that turns them. Could this have caused the motor to suddenly loose compression like that? It was running fine and then started to bog down and then just wouldn't start back up. Thanks for the help.

    You didn't say what ski you have, but it doesn't sound like a powervalve problem. Unless the powervalve dropped into the cylinder? Time to open it up and see.

    Its a 2001 gp1200r and the powervalves are still fine but they were not functioning due to the cable being torn up.

    Your PV problem is not causing a loss of compression.

    you need to rebuild your engine.

    Just got it all apart and found the hose clamp for the oil line in the back of the hull. Not good when you have a free oil line flying around. Definitely going pre-mix during the re-build.
