put a new front sprocket on the front -1 and a new chain??? The sound only happens during hard acceleration and its almost a whistling sound or a turbo/vacuum sound... its wierd.... anyone ever have this problem? It seems to have happened right when I changed the stuff above but may be something else which is always my luck

 

Could be your air intake "resonator chamber" became disconnected somehow.
Did you remove any fairings during the install?

 

Off-topic, but appropriate:

You need to change BOTH sprockets. Putting a new chain on an old sprocket is bad news. Check the service manual.

 

nope never heard a turbo sound on mine, THANK GOD!!!

 

Does the problem happen when the bike is in neutral?

 

I changed my oil too that day so I had the right side fairing off...

 

No its only when accelerating... not in neutral or when coasting

 

Let me ask it a different way: does it happen in neutral when you increase the RPMs?

 

Nope... never happens in neutral at all... must be in gear and accelerating

 

Check all your air\vacuum hose seals. Beyond that, try and figure out exactly what area the sound is coming from.
