    The issue:

    My scooter bogs out and has a horrible flat spot between slghtly open throttle and fully open.

    Things I've done:

    I have tried both the original (clean) air filter and an aftermarket cone filter, happens with both.
    I have recently renewed the exhaust baffle (to get through MOT).
    Fresh fuel and oil checked.

    Question:

    Does anyone have an ideas what could be causing the issue?
