I have a 1981 Kawasaki LTD 550 with 5600 miles. My gas leaks out the carbs when sitting, all four! Just started this. Was told fuel pump bad. where is it located on motorcycle? Thanks
If the carbs are leaking fuel then the float pins inside are not sealing ad the weight of the fuel in the tank is pushing out. your bike should not have a pump. it should be gravity fed. if your bike sat for a long time and you did not drain the carbs before putting it in storage the fuel goes stale and creates a varnish like residue inside the carbs. unfortunately the only way to clean it is to disassemble and clean them. not something a casual rider should attempt. it is something that should be left to a mechanic. removing them from the bike could save you some money, but not much. taking the bike in to a bike shop is your best bet if you have never done carburator work before. the mech can clean, reassemble and sync. usuall cost around 300-350 parts and labor at a good shop. I used to run a motorcycle service department. if you can do it yourself great. just dont get in over your head. it is harder for someone to pick up where you left off working from a bag full of peices the to be the one who took it apart and remember where everything goes. good luck

It sounds like the float needle valves are lletting gas run into the bowl,in turn running gas into the motor,and fouling the spark plugs. Have you noticed if the oil level seems to be going UP,or the fuel level is going down? Kawasaki motorcycles are prone to leaking needle valves in the carbs for some reason. And the longer it sits,the worse its going to get.Try this,...pull the spark plugs and see if they are wet with fuel.Then,unhook the coils,and spin the motor over with the plugs out.If it shoots raw fuel about a foot out of each or ANY cylinder,then that is your problem. JUST BE SURE TO DISABLE THE COILS BEFORE SPINNING MOTOR OVER,AND DONT BE CLOSE TO THE PLUG HOLES WHEN YOU SPIN IT OVER!! Good Luck!
Ign module cud hav issues..its on flywheel and a blackbox. U gittngas to those cylindrs..float cud b stuc on those carbs. Buy a clymer rpairbook..the best
The carb float valve is stuck, or the float needs to be replaced. The oil you see is probably being rinsed off the case by the fuel. Remove the carbs and inspect the condition of the float needle and seat.I would just replace it given the age of the bike. Check the float-if it's brass, shake it to make sure there is no gas in it. If there is, replace it. If it's plastic, put it in a cup of gas and make sure it floats. They do get saturated over time and need to be replaced. When putting it together, consult the factory specs for float level, set it and you should be back on the road. Good luck!
Is it poss to remove the float bowl while the carbs are fitted to the bike? I am fairly sure back in the eightys the float was addjustable, to controll the fuel level by bending slightly the metal tab on the float, when the bowl is removed check the level of fuel in the bowl and compare it to that in the others, the aim is to make the fuel flow stop at the correct level in the carb(by bending the float tab) while the bowl is off turn on the fuel push the float all the way up check if the fuel flow stops, also check the condition of the sealing washer around the float needle seating.
onee of you carbs needle and seat is not closing all the way if you leave the gas on and remove the overflow tubes from each carb yuo should see this one leaking make sure bike is sitting up right so fuel isnt just running to one side
The most common issue of bikes not starting after they have sat for a while is the carbs have gotten gummed up from the gas sitting in them. Gas breaks down and gums up the fuel and air passageways in the carbs after it sits for awhile. You need to remove and overhaul the carbs.
This is the single most common repair we see as motorcycle techs.
To be certain it is fuel related, it doesn"t hurt to spray some carb spray into the engine and see if it fires up briefly. If it does then you know its fuel related.
The 83 still used a carb and mechanical fuel pump I believe. And the fuel pump is probably bad. Check the oil and make sure it is not over filled with gasoline. Take the fuel line off the carb, and see if the pump squirts when engine cranked. Open the gas cap as well, so make sure a stuck purge valve is not holding the gas back. http://www.autopartswarehouse.com/details/QQFordQQLTDQQAirtexQQFuel_PumpQQ19831986QQAF60048.html
no fuel getting into the combustion chamber. the fuel gets there through the carbs. are you getting fuel to the carbs? is your fuel pump working? fuel filter clean? carbs clean?
hi,this might help,it sounds like one of your carb floats is stuck,this will allow the carbs to keep filling with fuel and ultimately overflow through that rubber hose,if it is only one then it is a simple fix(hopefully),get a long screwdriver and give each of the carb bowls a good healthy tap (with the handle end)hope fully this wil free it up and the fuel should stop running out,if it doesnt then you may have to pull the carbs out and clean the needle valves and reset the float levels...cheers
check the fuel pump, maybe it is not working. if you put a new accelerator pump, I wonder if it's same as the fuel pump. if so, maybe you need to rebuild your carb, clean the small fuel line in the carb, something block there.
