Here is the maintenance procedure that will most ensure good times on your CBX. You need 24 inches of 3/32 rubber hose. An extra-long needle nose pliers (mechanics call this "stork" pliers). A really long flat-blade screwdriver. And a container to hold a couple hundred milliliters of gas.

Whenever you aren't going to ride the machine for more than two weeks, use these tools to drain all six carburetor float bowls dry. Of course, you aren't running the overflow hoses on your bike, because they get in the way of maintenance such as this. And you have been riding the bike with Sta-Bil in the tank so the carb circuits always have stabilized fuel in them, and after draining, the residual gas that lingers in the carburetor's passages will stay fresh.

If you haven't considered why having Sta-Bil is important even though you are draining the carbs, consider this: even when on the bench, CBX carbs do not fully drain. At least 50 milliliters lingers in the carbs' passages. Here's a video that illustrates that. Having Sta-Bil in that fuel in important so that the carbs' circuits don't gel. What's more, the situation is even worse when the carbs are on the bike as the angle at which they are mounted ensures that even more fuel will stay in them when drained -- almost 100 milliliters more.

When you're ready to ride again, open the tank petcock and allow fuel to fill the bowls for a few minutes before attempting to start the engine. If an 80 through 82 model having the vacuum fuel shutoff, instead of cranking the starter for long periods, crank for just a couple seconds while clamping the auto fuel shutoff's vacuum hose then turn the key off and check your tire pressures. The float bowls will fill and save your starter and battery.
