    03 MSX 140 Runs great then will only idle

    Hello,

    I took my msx 140 to the lake yesterday and it ran great then it would only idle and when i hit the throttle it would only bog the motor down. Then after waiting about 30 seconds it would go agian. I took it to the dock to find that the emm was not getting any water to it. I fixed the problem and it still does the same thing. i took it back home thinking it would need to cool down but i took it to the lake today and it still has the same problem. the red light and check engine icon will flash sometimes when this happens but not every time. Any ideas on what to check?

    If the EMM has been cooked with excess heat then it may need internal repair.

    I only rode it for about 30 minutes before it started doing this. It can burn up that fast?

    EMM with zero water flow to cool it can cook in a hurry.

    Why was there no water flow through the EMM?

    the hose that runs from the emm to the exhaust was plugged.
