    97 GP 1200 stall

    my 97 GP 1200 will cutoff when i first take it out,it will start right up, i let it warm up a few minutes then give it gas it completely shuts off,starts right back up and if i play with the gas it is then fine,but seems to do it every time it sits for a bit,runs fine other than that,i am guessing carb issue,i rebuilt the motor and went through the carbs also,compression is 128 ,129 and 129.any thoughts is appreciated.

    Make sure you have the carbs synced, check for sticking needle, weak diaphram, and pop off.

    I had the carbs apart when i rebuilt the motor everything looked good except 1 check valve which i replaced,cleaned them out and set everything per factory specs,they may need synced so i am going to check that,right now it still has stock factory air box ,yep that is a pain,i do not recall what my pop off was ,but i know it was really high when i checked it,does anyone know what the pop off should be?

    I know what the rebuild means, but what does syncing mean exactly ?

    What about pop off and how do you check it!?
