The bike wont start. theres gas in it. the batter is charged. it just clicks over and over but doesnt turn over...is it the spark plug..and where is it on the bike if thats the problem.

Have you checked the coils

The line to drain the gas tank or carb? If you have auto shut off fuel valves(vacuum) set the fuel valve to "prime"(or check owners manual about fuel system)
Some bikes need a fully charged battery to start sometimes.
Will the bike fire on starting fluid?
Spark plugs OK?
Can you get a 1/4 " spark at the plug.
Contact me if you need more info.

Are you getting spark? If not, ck ignitin coil and wiring

Hi there!
Too much gas mixture or there maybe plug problems. If it doesnt start, charge the battery and start the bike with new spark plugs. Replace the plugs, this usually works.
Let me know if this is any good. Other options:

1. THe spark plug cable
2. The ballast
3. The jets are clogged
4. Poor fuel quality.

It won't start? or it won't turn over? If it won't turn over have your starter checked out and proceed from there. If it tries to turn over but won't start, change the sparkplugs and see if you get a spark. If you do not get a spark you should take it to a repair center. If you do get a spark with the new spark plugs, install them and see if it runs. If not see if it's getting fuel, If it still wont run whether it is getting fuel or not I reccomend taking it to a bike mechanic.

98 honda shadow ace wont start electric switch is sticking and the headlight doesnt come on when key is turned on

check comprsion. check valve clearance.

If you have spark them it must be gas. eather no gas or to much gas. Put it on chock, be sure the shut off valve is in on position.Now crank it over a few times , if it wont fire. Check the plug , is it wet or dry .If its wet then it may be flooded and needs to dry out and air out the cylinder.Try starting when dry. If its dry try putting a 1/2 oz of gas into the spark plug hole. replace the plug and turn it over . This will get them to fire up. Good luck DFD

Your bike needs 4 things to run-Fuel, Spark, Air and Compression. One or some of these are missing.

1) Crank engine over several times to start. Remove spark plug. If plug is wet and smells like gas then it is getting fuel.

2) Check for spark
Put spark plug back into spark plug cap and lay spark end along side bolt or part of unpainted head making contact and crank over engine as if to start. If no spark then is electrical problem. Try changing spark plug. Check grounds. If not plug or grounds then purchase a shop manual from your local dealer and ohms test all electeical componet resistances as shop manual instructs. Be sure components do not meet specks before purchasing.

3) If has spark and plug was wet upon removal then gas has water or just old gas. If you drained the carb via bottom of carb screw into a clean clear container and see stuff at the bottom then carb is dirty with water and or dirt.

If your bike has been sitting along time condensation will build explaining water and or gas will loose its kick after sitting too long. If you think it has been sitting a long time it is best to dispose of old gas and refill with new. Water can also get into tank from gas can when fully tipped upright so dont dump every last drop into the tank...most ofter the last couple of cups are water.

If bike has been sitting for a few days and was running fine before that, turn off gas, drain carb via bottom of carb screw, close off screw and turn gas back on. This will refresh the gas in carb.

If none of these are the case and you have good fuel, good spark...check air filter for air flow. If all this is good then you need to do a compression check. A simple way to do it is to stick your finger in the spark plug hole and hold it in there with some force and have a friend try to start the bike. If it blows your finger out then it has compression. If it doesnt want to force your finger out then you have no compression and is a piston and ring problem. The only way to test compression for sure it to purchase a compression tester from auto parts store that has an adapter for your size plug hole and do a proper test. I hope this helps.

• The first thing to do with ANY engine that has sat for any longer than a couple of months is to dump ALL the fuel in the tank and carb(s). ALL OF IT !! You'll want to refill with some high priced fuel that has fuel system cleaners (Like Chevron with Techron) not becasue you need high-test fuel, but because you need the cleaners. It's ether that or disassemble the carbs and clean out jets you can't find much less see. Your choice. The carb kits alone will cost you about $50 so a tank of high-test is looking pretty good, huh?

• Now the fact that you tried to crank the engine with old fuel has fouled the sparkplugs. All of them. Go buy all new sparkplugs.
