No fuel or no spark. Quick test: spray some starter fluid into air intake and try to start it. If it runs and then dies, you've got spark but no fuel. If the bike quit with no prior symptoms, check spark plug wire not knocked loose, fuel filter clogged. (You do have gas, right?)

My 2 stroke trials bike wont start. I thought id gone into reserve tank when the engine just died. Got heaps of compression still when i kick it over and it was running ok up until this point. Do you...


Hi, Christopher and the usual suspects are:
1. Fuel tank empty.
2. Fuel supply valve/petcock turned off.
3. Fouled spark plugs.
4. Engine flooded as a result of overuse of the enricher.
5. Vacuum hose to the fuel supply valve/petcock disconnected, broken, cracked, or pinched.
6. Fuel valve/petcock or filter clogged.
7. Discharged battery, check battery terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
8. Loose or corroded wire connection at the coil, battery or plug between ignition sensor and module.
9. Spark plug cables in bad condition and shorting, cable connections loose, or connected to the wrong cylinders.
10. Ignition timing incorrect due to a faulty ignition coil, ignition module or sensors (MAP, CMP, CKP, O2 and/or BAS).
11. Security alarm needs a reset.

I was driving it died and now wont start at all it turns over but dont start


As with any no start situation, you will need to know if it has spark to the plugs, fuel to the injectors, and normal compression.

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!

3. Spark plug gap to close or to wide.
4. Faulty ignition coil, module and or sensor.
5. Battery nearly discharged.
6. Damaged wire or loose connections at battery terminals especially the negative cable at "BOTH" ends, ignition coil, or plug between ignition sensor and module.
7. Intermittent short circuit due to damaged wire insulation.
8. Water or dirt in fuel system, carburetor or filter.
9. Fuel tank vent system plugged or carburetor vent line closed off.
10. Carburetor controls misadjusted.
11. Damaged carburetor or intake seals.
12. Loose or dirty ignition module connector at crankcase.
13. Faulty MAP, CKP, and or CMP sensors.
14. Incorrect valve timing.
15. Weak or broken valve springs.
16. Damage intake or exhaust valve.

Good luck and have nice day.

Sounds more like the coil is causing your problems. It overheats and causes the misfire you experience. Coil cannot be repaired. Needs to be replaced. Once the bike has died, take the plug wire off, remove the sparkplug and reinsert the plug into the plug wire. Now let the plug rest on the head. Metal part should be touching the head. Try to start the bike again. The bike wont start of course but you should see a blue spark between the electrodes of the spark plug. If not, swop the plug with another one. If you still dont see a spark it is probably the coil. Other possibilities are the generator and/or condensor.

Bike wont start turn over till batery dies. where


It will have a fuel filter in the fuel line (should be easy to find) but does not have a fuel pump. Firstly i would check you have spark on all cylinders as this is the most likely thing to be going wrong. Once you are sure you have spark you can start trouble shooting fuel and air delivery problems.
To check for spark remove a sparkplug, insert it back into its HT lead. Place the threads of the sparkplug on the engine block and crank the engine. A strong blue spark should be visible.

Bike wont sart dont kno why??


You didn't mention the spark plugs.Did you replace them?Check also for strong spark on the cables.Unscrew the spark plug's plug from the cable and keep the edge of the cable about half an inch from the engine (aim a bolt usually near the cylinder's head) and with the kill switch "ON" press the start motor's button and you should see a blue thick spark.
Also check for normal fuel flow from the tank to the carbs.Change a fuel filter if necessary.
