GP1200R Fuel Starvation when Hot?
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.

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.
