Hi, just wondering about engine noise on the fz8? my bike starts up and sounds
nice up until it gets hot (about 96 on temp) if i then stop and re-start the engine it sounds nice for about 15-20 seconds then i can hear a loose mechanical rattling sound? (gearbox rattle?) which seems to be coming from the gear change side if i pull the clutch in it makes no difference at all? when the fans chime in the noise stops until the fans cut off? then the noise comes back. The rattle is always there on a hot engine and there are no performance issues at all, I mentioned this on my 1st service rip off! and was told the mechanic didn't notice any unusual noises. Thanks for any input
I can't watch the video at the moment, but could this be related to the infamous "Yamaha tick"?
Or you know, judging by your description, I wonder if the fans themselves get loose while warm and stationary. I don't think it'd be something to really worry about.
disclaimer: I'm mechanically stupid.
Hi,finaly got my bike back from the dealers without much sattisfaction.They sent the bike to Yamaha in Surry for them to diagnose the problem,but after trying numerous bikes they have decided it is a characteristic of the bike with some being louder than others.Ha Ha.So it sounds like your mechanic has the same veiw.

Uploaded for sound comparison.
Here is my bike. New plugs and air filter just fitted. Oil has been in for 1700 miles. Bike is 2012 with stock exhaust. Never thrashed but does regular high speed cruising.
