    On my MB, as soon as I disengage the clutch the motor dies. Should it remain running or is that how it's supposed to be?

    Does it die right when you first try to start the bike or is it after it's been running?

    Tell us what engine/carburetor you have. It would help us help you.

    BGF 2-stroke kit

    It runs and drives fine, what am asking is "Should the motor die instantly when I disengage the clutch? Or should it keep running until I hit the kill switch?"

    It cranks right up and runs like a top when I drop the clutch....but if I clutch in to come to a stop the motor dies the instant the clutch handle is squeezed and the clutch disengages.

    Me thinks you need to screw in the idle adjust screw a little.

    so it SHOULD remain idling when I disengage the clutch? for instance, if I start it up, lock the clutch lever into the disengaged position, and park it using the kickstand and walk away...it should stay running?

    right now it dies the second you squeeze the clutch lever in.

    Yup, it should idle with the clutch pulled in.

    If the idle screw is set wrong it will die, just like you have now.

    Still don't know which carburetor you have but it should have an idle speed adjustment. Typically you screw the idle speed adjustment in to increase idle speed and out to decrease it. In being turned clockwise and out is counter clockwise.

    I always just leave the choke off. I know you're supposed to use it to help get the bike started...but when it's on I seem to have a harder time getting it started so I don't bother with it. I leave it in the "down" position.

    Your symptoms sound pretty similar to mine when I was getting a massive air leak into the cyllinder.
