I have a relatively new to me 2006 WR450. All free mods done, FMF exhaust, otherwise pretty much stock. I have been trying to figure out a strange noise that at first was intermittent, now is mostly constant. It is a high pitch whine, almost sounds like an electric alarm. It will make the noise with the motor running or off while coasting. The engine can be hot or cold. It seems to be coming from the front wheel. I have inspected the wheel bearings, front break and speeedo, they all seem to be fine. I took it to my local shop and left it for a few days and of course it ran perfectly…Anyone have any thoughts or suggestions? Thanks in advance.
