    Gp800 midrange hesitation help please!

    I have a 99 gp 800 that has set for 3 yrs .. I pumped all the gas out and rebuilt the carbs to start fresh along with 93 octane and a can of sea foam through the first tank..

    my problem is it come out of the hole just fine and runs great on the top end


    IF I AM AT SAY 2-4k and then go to wot it has a slight hesitation that is hit and miss between the 3-5k range before going on up to top end and running smooth..

    I am at a loss on what it could be it does not do it every single time but it's enough to be annoying

    thanks in advance

    have you changed the plugs lately?

    Yes 2 times actually thinking the replacements were not up to par as well...

    I've read and read and I've come up with 3 possibles

    1. Accell pump helps the midrange between piloti and main jets ..I didn't touch it when I rebuilt the carbs..

    2. Some say all the gp800 have a slight hesitation at midrange that it's normal...

    3. Some say with what's it's doing I need to turn the low screws out 1/8 turn and thst will fix it ...

    anyone thoughts?!?
