Wierd engine noise

[BORN TO BE MILD!]

This may be a stupid question, but i'll ask it anyway....

I have a new Atomik ProX140, it has only been idled for about 5 minutes, when its running, it sounds like there is a 'swooshing' sort of noise coming from inside the engine case.
Is this normal?

This is my first bike so I'm pretty clueless, (about bikes) but i know a fair bit about engines and stuff, so i should understand any jargon that is said,

Thanks again..........

it could be your airfilter sucking in air to the carby.

it might be the engine breather may have the clip still on it

Nah, i in clipped the zip tie in the breather pipe, It could be the carby, but I am pretty sure it is coming from inside the crank case, on the left hand side...

Well, the bike will be tested starting tomorrow, for 2 weeks on a hilly farm that my grandparents own, so we will know if it's ok after then. Otherwise, the big 30 day warranty will cover it!
