QuestionI have 1983 V65. Just clened carbs bike will not start, gas is going in the air box. Can you tell me if that is a fuel pump problem. Also filling cylinders with gas.
AnswerJim, not sure about your version of "cleaning the carbs", but there are O-rings that need replacing and checking the float valves and float levels, etc. that is required.
Fuel in the airbox and cylinders indicates plenty of fuel pressure/volume. What could be happening is that either the bowl venting is not all clear, which equalizes the fuel pressure inside the bowls or that one or more of the float valves are stuck open. This is somewhat common when replacing carburetor rack assemblies when they are dry. You have to tap on them some with a screwdriver handle or something that won't damage them, but gives them a little jiggle to help reseat the valves again. When carbs are dry the floats are hanging down and the needles sometimes get cocked, causing the carb to flood. At this point you need to pump out the excess fuel from the cylinders and air box.
Tap on all the float bowls. Keep the fuel turned OFF, change the spark plugs and try to light it up again. If it starts up, let it run for a minute or so to help clear the fuel in the cylinders and then turn the fuel back on, checking for leaking float bowls. Any leaks need to have the carbs tapped on and/or shake the whole bike on the centerstand back and forth to help seat the float needles.
If you didn't really completely rebuild the carbs, take them off again and do it right with new parts, inspecting ALL the passageways, jets and components inside.
