Possibilities are; handlebar kill switch is grounding out, kick stand kill switch is broken or needs adjusting, a bad spark plug, power wire to ignition has come unplugged, bad ignition switch, ignition system needs service, coil or coil wire has gone bad. This list is in sequence of likelihood.

What if my 1990 Kawasaki TS650 won't start when it has a brand new battery, spark plugs, and new gas. It will turn over but won't start. Any ideas?


Is this a TS650 Jet Ski, or a Motorcycle?

Did you turn the gas on at the tank? Did you check that there is fuel at the carburettor? If you try and start it, did you remove the spark plugs and see if they are wet? Does it have an automatic choke, that is stuck?

My bike is not starting, I've already changed both spark plug there were no problems on the carburetor also my batteries were fully charge yet my bike does not start... can you help me Identify the...


There are 3 components necessary for any motor to run-fuel, air(compression) and spark. Just because you have new plugs doesn't mean you have spark. Put them in the caps and ground them to the cylinder head and turn the motor over and look for the spark. If you have spark, install the plugs and plug wires, and turn it over several times. Pull the plugs and check to see if they have fuel on them. Run these 2 simple tests and get back to me with the results and I'll help you further. Good luck!

1980 Yamaha XS 400 Special First, How do you tell if it has an electronic ignition? Second, Can't get it to start. Have put gas in spark plug holes. Didn't hit. Bike has been setting on a dirt...


First, you need a good battery. The bike does have electronic ignition. Soak the carbs in denatured alcohol for two hours after removing the float bowls, then clean with spray cleaner. Spray into every large and small hole you can find. Remove the rubber diaphragm from the center of carb prior to cleaning. New diaphragms are $196 each. Check all fuses. Put in new spark plugs, NGK-BP7ES. Clean the air filter. Get a can of spray starter fluid and spray on the air filter. The rubber mounts for the carbs are likely to be a problem once it gets running. It looks like they are still available at Babbitt's, $53 each. If un-carburetored air can get into the joints it will lean the fuel mix and cause uncontrollable high idle.

Before you sink a lot of money into the bike, check for spark. If spark is present, coast the bike down a good sized hill without any spark plugs being installed. Put the bike in 3rd gear as you go downhill then let the clutch out to turn the engine over. Now ( using the clutch lever ), shift through all the gears then neutral. If the bike will not shift properly it likely has a bent shift fork. I can't find any forks avaiable. With a bad tranny I would put it back in the dirt floor building and find a newer bike. Here is a link to Babbitt's. Please rate my answer. Thanks.

Bike wont start.good spark to plugs.fuel pump working. side stand switch fine. neutral switch fine.


i have the same bike try this. Firstly check the fuel is fairly fresh, using premium fuel on this model seems to work well. drain a little fuel from each carb to remove poss water build up and get fresh fuel. if spark plugs over 6 months old or over 5000 miles change as zxrs` eat plugs a spark does not mean it is allways good. i have changed to irridium plugs and have not had problems since . before you take out plugs turn over the engine a few times then when you remove each plug they should be wet ,if one is dry no fuel so clean carb,remove plug caps before you do this and note exact location of each.good luck Bri.

BIKE IS NOT STARTING. HAS BEEN HARDER & HARDER TO START. HAS PLENTY OF SPARK & NEW GAS. COULD IT BE THE PLUGS & HOW DO YOU REMOVE.


Please check these things before you start taking stuff apart: Gas in Tank? Fuel valve turned on? Kill switch in the Run position?

My Kawasaki Z 750 (2005) won't start. Starter


If the Tach is showing some RPMs then it must be turning the motor over, if the bike is just coming out of storage it may be gummed up in the fuel system. try turning the fuel petcock off and then on a couple of times. try to start the bike. Failing that, you may have to drain the fuel and replace it with new fuel.
if neither of these work you may have to consult a local mechanic for a spark test and fuel test.
