    2000 GP 1200R Ruined? Son is bumming

    My son and I bought a 2000 GP 1200R last year. Ran great for about 15 minutes and then would shut down. Compression test was great, cleaned carb, fuel filter etc. Just found out that the #2 piston was not getting oil. Compression on #2 would drop to 38 after 15 minutes. Boat guy is telling me must do a rebuild for $2,500. Any other alternatives such as boring it out, new piston sleeve, etc? Thanks.

    Very common for an oil line to pop off or crack and cause you to lose a cylinder. You can either switch to pre-mix or change to new oil lines. Parts are readily available to fix it and you could make it a father son project Take some pictures of the damage where in Jersey are you?

    Between the classifieds here and ebay you will be able to get back into the water quickly and for much less if you do the wrenching!

    Hi Mike: Thanks for the response. SOunds like great advice. Didn't think I needed a new engine like this guy is telling me. I'm up near Lake Hopatcong, N.W. Jersey.

    It really depends on how bad the damage is. Most likely you don't have any lower end damage, and just need to replace the #2 cylinder and piston.
    More importantly, figure out what caused the problem and make sure you fix that FIRST.

    DONT FORGET TO POST PICS OF YOUR TEARDOWN/REBUILD !!!
