Hissing noise

[wessexrfc]

It may be mothing, but what I find is on part throttle I get what sounds like a hissing noise, had this before, but never worried too much, but I've fitted hard pipe kit, its still there is it just the dump-valve and nothing to worry about or is it

something else??

I found this on mine. At a certain throttle position the BOV (Forge) would hiss. Changed the spring from a green to a yellow and it's all good.
