What bike? what year? without anymore information, i would start by checking the fuel screw at the bottom of the carb....if this is a yz you'll want to close the screw all the and then back the screw out 2 full turns, or it could be the excel pump....when you took the carb apart, you didnt loosen the ssrew that holds the TPS on the side of the carb did you.....because then you have a throttle position sencor problem. but, i need more info...what was done, or changed when you rebuilt the carb.....im sure it is something minor

    also if your bike has a hot start.....it could be the little rubber gromit that goes around the hot start plunger if that rubber gromit is bad you could be sucking in cooler air and it will affect the air fuel mix.....but, i need more info i would say check the air jet (on the rim of the intale side of the carb where the air cleaner boot goes. may have dirt in it.

I have a 1996 sea doo xp model jetski, i have rebuilt the carbs and replaced all the fuel lines. i also removed the gas tank and thouroughly cleaned the whole fuel system .. it is still bogging a bit when...


any vehicle will bog if you give it full throttle from a standstill. You are dumping huge amounts of fuel into a engine that is not spinning fast enough to burn it.

Take it to a Seedoo dealer and get them to calibrate the carb. They have the diagnostic equipment,exhaust sniffer and the know how to do it. Also on twin carbs, they have to be balanced. They have the vacuum gauges to do that. It is not an expensive exercise.
