    GP1200R Fuel Starvation when Hot?

    All,
    I and a standup rider however I am a newby to sitdown skis. I bought a GP1200R and have noticed after I run it for a while and it is nice and hot, once turn ot off and let I sit it around for a while two things happen.

    1. Throttle bind a little (ie: becomes slow to return to back idle position after squeeze) although I found a post about this (ie: it's normal due to heat expansion and I have sanded the shafts to sort it).
    2 The other other thing is that the carbs appear to have be drained of fuel and have leaned out whilst sitting around.
    This gets so bad that I need to pump my fuel primer to get it to start it and I pump the throttle it just bogs and sound really lean - ie seem to be starved of fuel.

    Once it runs for a bit (about 5 mins) I seems to sort it self out however during this time it runs awful and I am scared that I am going to seize it.
    I assume the fresh air and fuel running through the carbs colls them down and sorts it out....is this normal behaviour - is it fixable?

    Thoughts or suggestions?

    Might be time to rebuild the carbs. Of all my crafts, the GP1200r is the hardest one to start. Hot starting for me was an issue until I rebuilt the carbs - then it became OK. Cold starting is still and issue though.

    you are absolutely right, time for him to do carbs.
    on the other hand, if you follow osidebill jetting specs , you will not have any issue either hot or cold to start the engine.
    never had issues with mines after a good rebuild , i bypass the fuel shut off valve , and use the reserve line as a fuel supply.
