    2006 GTX Limited build date and exhaust valves?

    Looking at buying a 2006 GTX limited with the 215hp engine. I understand the early 2006s have exhaust valve issues. Does anyone one know when they began installing the solid exhaust valves. How about where I can find the build date of the ski and also the motor.

    I understand that on older skis the build month and year is the last three digits of the vin but that doesn't appear to be the case on this one.

    Sounds like the owner gave me the wrong digits. Just looked at a couple newer ones and the vin did match the year.

    Still need to know when they switched to the newer style valves. Thanks.

    You have to go by the production date of the engine, not the ski. The production date is on the tag in front of the engine. Nobody knows for sure when they switched over. I personally looked at a 3/2006 production engine, and it had the old valves.

    Unless you're modding the engine, the stock valves should be fine. (if you run in fresh water)

    those exaust valves in a 2006 are a ticking time bomb.

    you can check the 2 numbers on the top valve and the 72 are the hollow ones (junk) and the 75 are the good ones.

    Looks like the ski was built 5/06 and the engine 11/05.
