Should the tank of a 1991 VXR be vented oris it pressurized? I removed the fuel lid(where you fill the gas) and it had pressure built up in it,because I could hear it escape. I just purchased the ski and it has a dead cylinder and I was trying to figure out why.I have yet to pull the motor and pop it apart. It has 150 lbs in the front cylinder and 0 in the back.I can see the piston doesn't have a hole in it,and there is no aluminum on the olg,so I suspect a ring snagged or something like that,but I will pull it soon.
