Hi everyone. I have a 1980 CB650C with mechanical slide carbs. The bike is running great, but I can hear an airleak on the float bowl vent "t's" between carbs 3&4 and 1&2. The vent hose just hangs out there and is not connected to the airbox, but when I spray carb cleaner at the "t's" the rpm's change.
So quick question - Are the float bowl vents supposed to have a vacuum? Is it affecting my air/fuel ratio?
Thanks!
Jamie
