make sure that your battery is fully charged to have enough cranking juice. It happened to my VFR as well, headlights & clock worked but not enough juice to crank. I had this problem with my OEM honda battery, and eventually replaced with aftermarket battery with higher CCA (Cold Cranking Amps). A good thing esp if you live in cold countries

this is definately a valve problem. The valves are worn and seated to deep in the head they are pulling through. get new a good condition head with valves or good used vales and have them fitted. I might have a head for you.

Sounds like a bad starter without knowing what sounds it made when you turned it over etc. if it did absolutely nothing when you tried to start it but started when jumped via solenoid it’s either wiring between the button and starter or wiring between the solenoid and starter itself

Hi, Lyrical what you need is a wiring diagram that you can find in the back of your service manual if you can not find the first and best tool you ever bought for your bike, despair not, I have found one for you that costs zero dollars.

over fueling , when was carbs cleaned out last and fuel system cleaned ? is choke sticking on slightly

kawasaki ZXR 400... | Answered on Jan 23, 2014


Like all mechanical issues this is just a matter of elimination.
There is no mention of the exhaust system in the comment.

Is the motor backfiring despite the exhaust? Is there a corroded suppression baffle increasing back pressure? "... looking back this issue has slowly got worse"

There is a balance in the explosive gases, based on the comment.
So it seems the ignition chamber gases / fuel mix is correct. But there is enough fuel air ratio to post ignite, seems like an exhaust side issue from the comments.

Still there is nothing like feet on the ground ;)

try removing your spark plug then turn your engine over a few times but be careful there may be some oil or gas that sputters out so have a rag ready. Do that a few times until you dont see anything coming out then replace spark plug and try starting it again. If that doesnt solve it you may have to replace you rings ( on the pistons)

Try looking under seat on top frame area. See if that helps

look at coil earth for clean connection

Remove the silencer and clean up the down pipe and silencer ends. Use a liberal amount of exhaust repair paste and push the silencer back on. Refit the clamp that holds the pipes together and replace any perished rubberised band that may be used. Run the motor on idle for about 10 mins to harden the paste and the leave overnight. Recheck the clamp for tightness and hopefully all should be well with the world, the sun will be shining and you can go for a ride.

hi you dont say what model kawasaki you have im assuming you have a transverse four like a z1000 generally speaking as you sit on the bike the outer cylinders are 1 and 4 the inner cylinders are 2 and 3 ,now again im assuming you have two coils, each coil has two plug leads
coming out of them coil number one will serve cylinders 1 and 4 it doesnt matter which of these leads goes to either 1or 4 as bikes use a wasted spark system and will spark on the exhaust stroke as well, coil number 2 will serve cylinders 2 and 3 again it wont matter which plug lead goes to either 2or3 ok now for the tough part
you need to find the sparking point for no1 cylinder remove no1 spark plug probably the outer left cylinder as your sat on the bike and turn the engine over by putting the bike in gear (only do this with no plug leads connected as it could start unexpectedly in gear ) and push or bump the bike gently with the clutch out to bring the piston to the top of the bore a small torch would be handy for this to shine down the plug hole you then need to find a timing cover on the outside of the engine
you may need a service manual for this as there are many variations but usally there are two pick up modules one for each coil the timing marks correspond to each coil with cylinder 1 at the top of the bore the timing mark should be near number 1 pick up module now that you know which module number one is follow the wiring back to the coil ,each pick up wiring is a different colour like black and orange wires for one coil and black and green for another when you have found number one coil attach plug leads to it and fit them to cylinders 1 and 4 you then fit the remaining coil with plug leads to 2 and 3 cylinders refit the spark plug take the bike out of gear and go for a start good luck with this

I'll need some more information. Does the bike start at all? Does it idle fine, but then dies if you give it gas? Try to explain in detail what is going on so I can help you with this. There are a few things to check for, start by making sure your gas is good DON'T USE ANY GAS WITH ETHANOL (corn stuff) and that it is new. Another thing is to make sure you are getting spark. A simple way is to take the spark plug out while keeping it in the wire and touching it to the outside of the engine (grounding it), turn the motor over and you should see spark. If not, thats something you will need to correct. You don't have a year or what type of motorcycle so I'm assuming its a late 70's, early 80's KZ400 you are talking about. If so, the points could be the culprit as well (if the spark isn't going). But for the most part, the "needle" settings will only help with it's ability to rev high (main jet) and if it dies at idle, your idle jet is plugged up. Get back to us on the specifics and I can help more.

TO ELMINATE THE STARTER, FOLLOW THE WIRE FROM THE + SIDE OF THE BATTERY TO THE STARTER REAY IE SOLENOIDE, YOU WILL SEE 2 X NUTS HOLDING THE CABLES TO IT, THE SOLENODE IS A MAGNETIC SWITCH WHEN YOU PRESS THE STARTER BUTTON THE SWITCH JOINS TOGETHER THE 2 WIRES, TO TEST THE STARTER MANUALY YOU WILL NEED TO JOIN THESE 2 WIRES TOGETHER,EITHER BY REMOVING 1 WIRE AND JOINING IT TO THE OUTHER. OR BY USEING AN INSULATED PAIR OF PLIERS AND BRIDGING BOTH CONTACTS, BA AWARE THAT SPARKS NEAR TO YOUR BATTERY COULD CAUSE YOU BATTERY TO EXPLODE AND CAUTION SHOULD BE USED WHEN ANY BATTERY WORK IS UNDERTAKEN, SAFETY GLASSES SHOULD BE WORN AND PROTECTIVE GLOVES, ONLY CARY OUT THIS TYPE OF TEST IF YOU ARE CONFIDENT YOU COULD DO IT WITHOUT CAUSING INJURY,
