Dave I think Tonio is refering to his 600 Monster and that originally had a Vacuum fuel pump and no return path. So it will depend which fuel pump he has used, Ones of Carb'd CBR600s, ZXR400s, R6s etc should shut off when the fuel level in the float bpwls is high enough to shut the needle valves and then the back pressure should shut the pump off Checkout the Desmo Due Paddock on Facebook Last edited by skidlids : 15-Mar-2009 at 10:52. |
