Hi guys, posted on here a while back that my bike started making the odd 'shhh' noise when I started her up,

Well now she does it every time I start her and have the choke on up to 3k revs. All I can describe it as is 'shhhhhshhhh' and it only happens at 3k revs, always with the choke on, and sometimes without.

Is is the cam chain or something? My mates ZX6 used to do this and it was the cam...

Any help appreciated...

Jake
