    2001 XLT 1200 bogs and sometimes dies at WOT and turns?

    Ok to start off I just took out my ski for the first time today after completely rebuilding the carbs with new Mikuni kits and following Osidebill's recipe with new main and pilot jets, needle and seat and aftermarket flame arrestors. I also did the drilled return line mod. The ski ran awesome! I was out for about 15 minutes when I gave it WOT and it the ski took off but then started to bog about 2 seconds later. I let go of the throttle back down to idle and gave it WOT. It bogged and the ski died. Ski started up right away and the ski runs fine if I don't give it WOT. I also noticed that while doing sharp turns the ski would bog also. Any ideas why? I called it a day after that.

    -I've completely rebuilt the carbs with new mikuni kits
    -Did Osidebill's carb mod
    -drilled carb return line done
    -all three powervalves were removed and cleaned out completely
    -installed waveeater clips and the waveeater power valve couplers
    -Fresh fuel
    -completely disassembled the fuel selector and it was clean as a whistle.


    I've read other thread suggesting a fuel supply issue. I checked the stock fuel filter and it's clean and I added another aftermarket fuel filter right after the stock filter. Would 2 fuel filters in a row cause this? Any other ideas?

    did you pull the sending unit out of the tank? The reserve line is known to bottom out against the cap on the end, and flapper doors stick/warp closed

    double check your restrictor jet to make sure it doesnt have a piece of trash in there

    ^^^

    when you drill the restrictors in the carbs, you install a main jet into the return line... right?

    Many here have recommended NOT using the waveeater couplers because they cause shaft wear. Do a search on here for more info.

    I for one recommend them... the trick is to install the coupler, and then center and "push" the coupler into the opposite side until it bottoms out, then exercise the entire linkage open and closed by hand to make sure there is no drag, and that everything is centered.

    I have seen the stock plastic couplers so worn that the #1 valve either wont hardly open, or it drops too low and rubs on the piston
