The VIN number will be on the upper front end of the bike and it's 17 characters long. Once you have that number, click this link - VIN - and enter your VIN number information. It will give you all the details of your bike.

The engine number would be located directly on the engine. Most are toward the back of the engine, behind the head cylinders, on a flat part of the engine. You will, most likely, have to remove a few side pieces to find this number.

Hope this helps. If you find this information useful, please vote on this post. Thank you.

I don't know how to open your gas cap but I can tell you NEVER use anyting but graphite on any key mech.

I would check the spark plugs for fouling and change them out if needed. Other than that, I'd agree with Gregg and ask for more information. year of the bike, does it start and ride, is this an intermittent issue or all the time?

When you say no power through the ignition, do you mean the bike is completely dead with the ignition turned on? Nothing at all works, no lights, brake lights, indicators horn etc.?
If that is the case, then first check that the battery has a charge and the connections are all clean and tight.......and connected the right way round. My bike has a parking light position on the ignition switch and this allows the little parking lights to come on with the key removed. If yours has the same, see if that switches the light on. Do you have a permanent live outlet that you can test? If the battery has power and is connected properly and nothing lights up after doing these checks, then it is either a main fuse or ignition switch problem.

If you do have lights then at least the above is all ruled out and the problem now lies in the starting circuit. Is the kill switch set to run and if so is it working properly? By that, I mean even if it is in the starting position is it actually functioning properly and has clean contacts, all wires connected etc. The same goes for the start button.
At the solenoid there are 2 connections that you will have bolted onto when you changed it. Turn the ignition on and short across these 2 connections with a screwdriver momentarily and see if it spins the starter. If it does then the relay may be faulty. I will attach a youtube link that really explains everything in plain language and is by far the best tutorial I have come across for this type of problem.
Good luck with it all, Steve.

by placing your hand over the air intake you are making the engine create a vacuum that is drawing fuel into the combustion chambers
this indicates a lack of fuel to the carby or blocked jets in the carby
look for fuel filters , blocked petrol cap , problem needle and seat or give the carby a good overhaul.

could be a bad O ring somewhere, but could be bigger problem. Maybe gasket or cracked head. If coolant in oil it is probably the latter


kawasaki ZZR 250... | Answered on Jan 26, 2015

You didn't say what year model, but really not much has changed on the GPX over the years. Which makes this engine swap a snap. You can try ebay for a used engine or possibly someone parting out a bike. Also, a company called Factory Powerhouse, they sell bolt in (pit bike) engines.
Here is the link, i hope this helps.

Well not knowing what motorcycle you are working with I will give a general answer.
You may have a tube that is between the carbs or on the intakes. That tube might have a hose hooked to a crankcase breather.
If so one reason for the oil could be a person over filled the crank case with oil.

kawasaki ZZR 250... | Answered on Aug 25, 2011

It is flooding. Check for a float sticking or a needle and seat sticking open. It could also have a hole in a float that is it keeping open. (The float could be full of fuel and failing to float).

The red paint color is called Metallic Ruby Red Sorry I do not have the code # for the paint but you can order it from the link below.


kawasaki ZZR 250... | Answered on May 05, 2011

definately flooded
not sure of your model but if it has a vacumn fuel tap there is no OFF position
you need to drain the carb bowls with the small drain screws at the bottom, and make certain the air filter element is not full of fuel, and check the oil is not overfull due to fuel contamination.then try and start with full throttle. Do not run the bike with fuel tap in PRI position or it may flood again

If it has an off position on fuel tap
check air filter
check oil
turn fuel off
start with full throttle
turn fuel on

Hi,,it realy comes down to how much do you want to pay? you could use a good mineral based oil,,that is not expensive or you could go to a semi or full synthectic,that will cost more.

oil change should be done at every 5000km,,and in winter you can use 10w-40/ 10w-50 and in summer 20w-40/ 20w-50.

as long as you change the oil every 5000km and of course not using supermarket brand oil,,then the choice is up to you.

The timing mark can be found in the stator housing on the riders left hand side. It is behind the small round plastic plug approximately 20 mm on the top of the stator housing which is above the large plastic plug approximately 50 mm in the centre of the stator cover.

The site below has over 3000 manuals for free download. I could not check to see if your bike's manual is there because your posting didn't say what year and model you have. Please rate my answer.
