High pitch whine

[Brownie]

My shaft went at 161,000K. Have had a shaft go before (Moto Guzzi). A vibration and roughness , more so on left corners turning into a sidestreet and rising trottle, from memory. Pop your swingarm off with tyre on, it is not hard - have even done it single handed. When re-assembling roll the arm up to match the engine side (and as the box is in neutral) , rotate the engine side with your fingertips to align the press pin hole - that's the only trick to it. Good time to replace the rubber boot too. How many K on it ? 

Got 40000 its not really bad or anything just annoying ,Ill check her out

Sounds like your shaft drive is acting up.  Could be worn gear or u joint..

OR.
It could be your significant other whining your riding.     Hide her shoes.  The whine will disappear sooner

LOL
