    New FZR with 3 hours - strange noise after engine shutdown

    Hi all,

    The engine has only 3 hours and is working ok (top speed and acceleration is ok).

    After engine shutdown, the engine keeps making a strange sound for a few seconds, like if something keeps rotating and slows down until it stops. The sound looks like a seized bearing (it is not the bilge pump).

    Anyone with similar problem?

    Thanks

    What I supect you are hearing is the supercharger spooling down after the engine is cut off which is normal now that the supercharger and it's bushings have broken in. This noise can be even heard much louder with a aftermarket air filter installed. Tommy Jordan

    Mine makes a sound for a few seconds after shut down, but it sounds like it's the fuel pump or something to me. Doesn't sound abnormal, similar to my truck after I turn it off.

    It really does not sound normal to me.

    That's the bilge pump still running after you shut it down. I think it runs for about 30 secs after you turn off the ignition.

    That is 100% normal. You want to hear that sound it's music to your ears because the day you don't hear that your clutch is gone.

    I was worried that some bearing had failed.
