Gasoline leaking from air box

[KEITH KRAUSE]

I just checked and the gas is coming from #2 however the #2 is not hooked to the tank. #3 carb is hooked to the tank I am looking at 1-4 while siting on the bike from left to right is that correct?

Jason, I would take off the bowl to #2 and remove the float needle valve.
Look inside the valve seat and check for dirt. Take it out to get your best look and clean it with carb spray and a q-tip. If your valve has an o-ring, don't get spray on it. Inspect the o-ring and replace if it looks like it could be leaking. Now inspect the tip of the valve. If there is a ring worn into the tip, then the valve is probably leaking and needs replacement. It does'nt take much for the valves to leak. Also, check the small spring for operation. If the spring has become weak, the valve will leak.
Also, clean up the float assembly in case it's sticking due to dirt/varnish build up.

If your valve has an o-ring, don't get spray on it.

That is a good point. Spray cleaner is hard on o-rings. It shrinks and deforms them and they become brittle much faster. It's easy to cause problems with o-rings by not removing them before cleaning with sprays.
