    The bike bogs when you are riding it? Ride it again, but pull the choke on while you are riding it, and see if the bog goes away. If so, you are too lean.

    You should have a 165 main jet at sea level.

    If the bog comes from snapping the throttle open quickly, that's another issue altogether, and can be cured by tuning the accelerator pump.
