I have a 2006 katana 600, your problem is what I had. Very simply and cheap fix. You need to get new hose clamps/clips for your fuel hoses and minly the hose that puts suction out. You probably have an air leak like I had. This fixed my problem.
Hey, I'm getting ready to buy one of these from a person, and I'm sure it probably has similar problems. FYI If you are going to replace any one part in a multi carb bike you must rebuild and replace all the jets, floats, fuel valves, bowl gaskets, and everything. It's a complete rebuild, not just one piece, just saying 😊.
Hey i know what you are going through ,i have a 98 with 8k miles rebuild the carburetors synchronized them ran for a bit then more problems, i didn't give up now i have a bike with a bunch of new parts and no start,but good luck brother
Why you all ways have to take this carbs more then 3 times😂😂😂.I have 2006 Suzuki katana 600 trying to put it back together. Now is my 4 time taking the carbs out . Good luck on your rebuild.
The floats in the carbs have to be properly adjusted at at least 13mm from the base of the carb to the top of the float,to when the float touches the float needle and don't compress on it or it won't start or it will give you problems
Have you fixed it? One overseen issue is the fuel line and filter installed/running too low and/or faulty fuel valve. The reason being that there is only natural flow present, no pump.
I think you have a vacuum leak from one of the carburetors make sure the vacuum line it's connected with the petcock and it's leaking gas from one of the braiding house because one of the carburetors the gas needle it's not closing right when you take the carburetors out blow air from the gas line make sure the air is not going through when your closet tested out one by one I got the same bike let me know if this information helps you out drive safe
