I have noticed that when I am in gear, and I pull the clutch in, I can hear a whining noise, basically sounds like engine braking but quieter. I assume this is my clutch "dragging". If I switch to Neutral the noise goes away, switching back to gear, it comes back, this is even with the clutch pulled in. The bike has 35k or so miles. Original clutch. Two previous owners, I have no idea how it was treated by them. Anything I should do to remedy this? I realize we have a "wet" clutch, and that some "viscous drag" is normal when the clutch is cold. I have seen this after I have been riding around though, so I am concerned. I am going to check my rotors and brake rub on the center stand to rule that out. Assuming it is indeed clutch, I guess I should look to replace it?
