When i try to start my bike up it wont go, just wont fire, checked everything it has spark ect...some days it will go fine, but other days it wont, when i get it going it runs fine, if i turn it off and leave it for 5 mins it wont start again, im thinking its a fuel issue, when i checked the hose going to the carby it had fuel in it so it must be getting fuel, is it flooding? what else can i check, please help me out, thanks

Check the air filter if its clean take the carb apart and clean it with something like b-12 or i use wd-40 on my bike so it wont eat the rubber gaskets

I had a similar problem with my zxr750 and it ended up being a simple fix.

The problem with a number of Kawasakis carburetterd models is that if the carbs are not 100% fueled up the pump cant prime them enough to get it to start.

You need to hard wire the pump to get it to fill the carbs right up and it will fire straight up.

First thing you need to do is find the plug for the pump (Mine is on the right side under the side cover so you will have to remove that first) Then once you have found it up plug it.

The plug that is joined to the pump is the end you need.

Now run some wires straight off your battery terminals( You should already have the seat off if you removed the side cover) long enough to reach your fuel pump plug.

Check the wire colours and remember that black is going to be your earth.

Carfully touch your wires from the battery straight to the plug wires and you will hear the pump start to pump.

Contiue to do it until you hear a difference in the pump - you will hear it load up with pressure .

As soon as you hear this stop it will only take about 4-5 seconds of contious pumping.

Then connect up the plug again a little spray of areo start/start ya ******* and hit the start button it should fire up instantly.

I find that if i leave my bike for any length of time un started its always a bit of a ***** to fire up.

Good luck and i hope this helps you out.

Hi
Sorry about your prob - for any motor to work it needs air, fuel and spark. This means checking carby, tank and fuel line and electrical system.
You will need to establish you have fuel being available at the carby at all times + spark when ignition is turned on and motor turned over.
I feel its an electrical fault as when it starts it goes ok and when it stops you have probs getting it going again.
Get an electrical circuit diagram if you can and trace the wiring from the battery to the main switch to the starter - motor and ignition circuits. Make sure all connections are clean and tight
and that you have a good earth connection (maybe more than one)

Check also fuel lines in case you have a blocked air inlet into tank (it would collape otherwise) or a blocked return fuel line - fuel pump is another area of potential failure.

Quick check of fuel system is get a can of Engine Starter (don't know what brands you have whereever you are but we have one called "Start ya Bastard"- usually an ether based spray.
Spray into carby intake and see if engine starts and runs - if it does but won't start without spray its generally a fuel problem.
