    Angry Half Tank Blues GPR

    I have a 2001 1200gpr that had a fuel issue (when it was still running) I am still puzzled over. Had the ski 3 years and never ran it down to 1/2 tank of gas till this year.... when it got to half tank it would lose power and be very slow to accelerated and couldn't get to it's regular top speed of only 58. Now mind you I am not riding with major waves, and this would be the same in flat water. I toped it off it would run great again. At first sign I changed out the fuel filter, no help. A few weeks ago I wouldn't respond to a full tank...Zero compression in #3.
    Any ideas as to what the could have caused this problem before I go down that path again...
    I have checked the tank pick up screen, tubes, check valve, selector valve, hoses, and have since rebuilt the carbs after the death of #3. found nothing
    What have I missed?
    flame arrestors
    riva stinger single pipe

    Check those powervalves!!!!! Take the covers off and see if you've dropped a valve.
