Give it alittle more fuel on the bottom by adjusting the fuel screw. I think it is a fuel screw on the 06, I haven't looked at one up close. There should be a little adjustment screw on the carb. If it is on the motor side of the slide then it is a fuel screw and you should back it out to richen up. If it is on the airbox side of the carb slide then it is an air screw and it should be turned in to richen up. IF you bottom out the air screw or back the fuel screw out past about 3.5 turns then you need to go up on the pilot jet.

Hope this helps alittle.

The fuel screw is located directly underneath the front of the carb. It's really hard to get to and unless you have a special tool you have to pull the float bowl off to adjust it. You can try screwing it out in 1/2 turn increments and see if that helps. You may need to also go up on your main jet though.
