Hi guys and girls
Recently when I start up my bike she's been making this really noticeable whizzing sound from the engine while she is cold, as she warms up it progressively gets quieter, I'm not saying its louder than the exhaust or anything but while it is sitting there warming up I can definitely hear it and I haven't heard at all in the over 2 years I've owned her.
It almost sounds like a chain going round like the normal chain near the back wheel except for in the engine, I don't really know an awful lot about bikes so I have not even a clue for what it could be.
The reason I'm posting about it now is because tonight while I was riding around I started to hear it when accelerating, this time it was even louder than when the bike is just sat there warming up except for this was after 20 minutes of riding so she was definitely warm by this point.
She is a 2001 FZS600 with over 43k miles, she has never had any work done to the engine as far as I'm aware of (except regular oil and filter changes of course), only thing I've ever done even near that area is replace the carbs after my old ones started leaking fuel, however this work was carried out over a year ago.
Hope someone can tell me what it could be and if it is something to be worried about or if I'm just being stupid.
Thanks in advance guys.
