Hi i have a CBR400 aero and it just back from having the carbs balanced and it runs fine but when its stood over night i find it sitting in a pool of fuel I think it might be the float bowl gaskets or O rings but it does not seem to leak while riding any ideas and if it is the gasket/Orings where can i get these from

Many thanks

Does your fuel tap shut off properly?? The do tend to stop working after a long time

I have checked the fuel tap and it works fine however i have never turned it off before in the 7 years and never had this problem as i thought the fuel pump would stop the fuel , could it be the fuel pump need replacing ?

Thanks
