    Sudden onset of excessive vibration - any ideas?

    Riding along on our FZS yesterday and out of nowhere it started to vibrate ptretty heavily. Gets bad over about 5k rpm. Any ideas? TIA.

    Check your pump and grate area. Something is stuck in it. Stick, trash etc

    Or cavitation caused by debris damage to the pump

    That happened to my wife on a VX Deluxe. Running fine. Slowed and idled for a minute. Throttle up and at @5k rpm, bad vibration and only barely 5mph. A stick about the size of your finger wedged on the back, intake side, of the impeller.

    Thumbs up for the suggestions - a small plant had wedged in next to the impeller. Given the size of it, I wouldn't have thought it could cause that much trouble, but all seems fine now that it's gone.
