Noise question

[loudmastiff]

So I was out riding earlier tonight and noticed my bike started to make a new noise... Can't tell where it's coming from.. But noticed it started doing it after engine warmed up.. Sounds like a fluttering or almost heavy breathing kinda.. No loss in power.. Still runs good.. Almost sounds like a pump whining kinda.. But it has me a Lil worried like nowI wtf did break.. Woman's getting pissed.. Lol

There is a PCV type check valve coming off rear cylinder head (Black and white plastic in line with breather hose between rear head and air cleaner backing plate)...sometimes they fail and cause a strange noise like your describing...you can either replace with new, or just gut that one out and put back in place.

Damn Andrew nice analysis there!:2thumbs:

Now can you solve this one?

If I leave my wife at home and I go riding a while alone, I'll park my bike and go inside the house and I hear this whining sound over and over. Can you fix that? :roll:

Not sure what Andrew will suggest, but I just leave my earplugs in
