    Dies when I twist the throttle

    2004 with 295 miles. NOS tank. New petcock. clean (strained)gas). Rebuilt carb. Sprayed carb cleaner through every orifice and hole I could find.

    Starts and idles. When I twist the throttle is bogs down and dies.

    Remove the pilot jet and thoroughly clean OR replace. Add a double dose of Seafoam to fresh gas and run for 15 minutes. Let sit overnight and run again with the fuel mixture. Repeat for a week and let us know how it works. You're welcome.

    P.S.- I had the same issue with mine, worked like a charm.

    It sounds to me like you may have lost your main nozzle when the carb was apart. It's the silver bushing looking thing in the carb parts pics. Without it it messes up your fuel delivery when using the main jet... giving it throttle. The bike may run at idle, because it is using the pilot circuit at that point. Give it throttle and the main circuit kicks in, and without the parts in the right places, it pukes and dies. It is a very easy part to loose when disassembling the carb, and it's happened to many of us.

    The main nozzle is in place, but I did not change it. I have the carb off again, I will R and R.

    What do I check in air box? The air filter is new (dealer item) and I cleaned all of the dust out of it.

    Open the idle mixture screw another turn and make sure the hole in the pilot jet is clear.
