About 4 months back I replaced the stator on my 2007 900 Custom. Since then I've had to pop off the generator cover to try to fix a persistent oil leak. A week ago I did this again, and while the leak is gone, I now have this high-pitched whine coming out of the bike. It increases in pitch until I shift, drops down, and then increases again through each gear. After searching through the forums, I am seeing other people with this issue and the recommendation that it is the stator going bad (which sucks ). What is weird is that this whine seems to disappear after the engine warms up and I've traveled for while. Thoughts?
