    Leg bone connected to the.... Power-valve!

    2001 GP1200R.

    Tonight was just admiring/readying the ski for tomorrow's activities, when I noticed this cable was loose from where it was supposed to be. The apparently is how the PVs get pulled for lower power/RPM operation.

    I have no clue how long this cable was disconnected for; but what if any issues, problems, or symptoms would I have felt/seen on the water? I can tell you this - hot starting is a little rough without blipping the throttle.

    Guess I'll give it a go tomorrow now that its properly connected

    Pics coming

    Just adjusted the cables per servce manual. They were very, very loose and required about 3~4 full turns on the 10mm nuts. Definately one fell off, and not 100% positive the valves were going in/out 100% stop-to-stop. The previous owner had Wave Eater clips installed, and the valves are free to move (no binding or grit).

    You aint kidding!

    Last weekend on glass the ski went 65mph and that was with the PV cable off and UN-adjusted I think the PV was working in one direction (WOT) but not the other, and wasnt as tight as it could have been. I actually had the gut feeling something wasn't completely right that day.

    After fixing the cable I saw 66mph on medium chop. My butt dyno approves the added mid-range and mine was the fastest ski of those who wanted to race.

    /thumbs up to free horsepower and self maintenance!

    Just fyi if your having issues starting it hot your probably due for a carb rebuild. Shouldnt be any issues hot starting.
    By any chance is there any difference starting it now with the pv's closed during start?

    With PVs closing full now, hot starts are not any better off. Is this a sign of one particular component in the carbs starting to give trouble, or something else perhaps?

    I was planning to rebuild the carbs end-of-season, while at it I was planning to do the following. I'm kind of a one time get everything done at once person, but if the carbs are needing rebuild right now then I'll probably change this plan:

    1. Flame arresters
    2. Jet kit and full parts to match the mods
    3. Reed upgrade
    4. Upgraded prop
    5. Hull reinforcements

    I already have Riva intake grate, T-Handles needing to be installed, DPlate/chip, and a pump seal kit.
