Hissing noise at 4000 revs?

Hi, :)

 

As per title really. I was accelerating down a slip-road today and there was a quick high-pitched hissing noise just as the engine went through 4000 revs.

 

It happens every time when revving past that precise engine speed. It also does it when stationary too.

 

No other signs or symptoms. I'm slightly concerned, but I'm hoping its a hose or pipe leak? If so any thoughts as to how to narrow it down? :search:

 

Thanks in advance.

reed valve top plate, check the 4 nuts on the square valve on the stream of T2

 

Bit of a highjack, but also a :bump:

 

This may also be my problem, as I get a wooshing type noise, but only above 4000, when T2 is online. Unfortunately Ric I'm not sure what part you are referring to. Any pics??

 

cheers
