Hey everyone, whats up? I am new to the forum, hope someone could help me out. My name is Tom and I have a 2001 ZX9R with about 9,000 miles. The bike is well maintained. I've been having some carburetor problems with my bike lately. During idle the engine runs very rich. Unless I am racing the engine, the #2 carburetor loads up with fuel causing the bike to shut off. First I pulled the spark plugs to determine which cylinder was flooding, I noticed that the #2 piston was wet with fuel and full of carbon. I removed the intake manifold to get a better view of the main needle in the top of the carburetor. During idle I could see the fuel pouring into the top of the #2 carburetor. I pulled the #2 carburetor bowl off to check the float and valve, everything looks fine. Since the float valve seat is part of the carburetor housing the only thing I was able to do was clean it. I even cleaned the main jet and checked the main needle assembly. The #2 carburetor was still flooding into the cylinder. I then started swapping parts with the #1 carburetor to try to narrow down the problem. I changed the float, float valve, main jet and main needle assembly. No matter which part I changed, the #2 carburetor still flooded the cylinder. I called some local shops but received some very expensive quotes which consisted of the purchase of a new carburetor. I am stuck and could use any advice.
