You blow down the FUEL INLET hoses to test the float seals.
The breather/overflow pipes are open to atmosphere all the time.
cbr900racer77 has a point - and I am curious too as to why the fuel is only leaking when the bike is running.
Are there any other symptoms of this leak ? - Engine runs rough etc ?
