Squeeking sound - upper right side engine

Hi fellas!
Today I noticed a weird sound located at the upper right side of my engine.
When I start the Mille I can clearly hear a squeeking sound, which is repeated about 10 times in 2seconds. When I raise the RPM in neutral, the sound seems to dissapear at about 4000RPM+ but I think I can't hear it because of the Arrow can, which starts screaming loud as f**** at 4000.
The sound gets a slightly higher frequency when riding the bike. When I twist the throttle, it gets a bit louder and is noticeable in every gear!
What could that be?

The only extraoridinary happening for a long time was today- my quick release gastube thing opened somehow and spilled about 1 liter of gas on my rear tire and Exhaust, then I spilled about 5 liters of pure water over the bike to prevent it from burning.

Greets, Aleks

P.S: The sound sounds "rotating"

Hello mate, if it were me I'd give Griff a quick call at Aprilia Performance. Just in case oil isn't being pumped where it should be. Its probably something simple, but I had an FJ1200 that started squeeking and oil wasn't reaching the top end of the motor. At least it would put your mind at ease.
 
just a quick guess...
could it be the waterpump?
a while ago I lost pretty much coolant
 
Check the spark plugs / leads are tight...sometimes a loose lead could sounds like a ticky squeak.
Also torque the hard bolts just incase the lost coolant event strained the head gaskets.
 
Tricky one. The sound is distorted on the vids which is unavoidable but maybe it's an induction leak?? Have you checked the security of the airbox -throttle body clamp or the lower throttle body clamp screws...just a guess?

No,
it has nothing to do with the clutch, was one of the first things I thought of
 
allright guys, today I had some spare time, so I decided to take a look and try to solve the problem...
I did!
One of the spark plugs was pretty loose- nothing else!
Thanks for your help guys!
