Bike will not spark but gets gas - 1988 Suzuki GSX 600 F (Katana)

first try a new spark plug, if you get spark check gas filter, have spark ,have fuel, have timing it should start

NO - SPARK
Check for spark at spark plug.
1. If no spark, test the wire to the coil with test light and see if you have power to coil.
2.If no power to coil, make sure your on/off button is on and working.Use test light.
A. Power at the switch but not at the coil indicates a broke wire from switch to coil.
B. NO power at the switch indicates ingintion switch is off or faulty and not sending power to your switch , make sure key is on. Use trest light.
3. If you have power to the coil but no spark from the coil - replace the coil

SPARK
Check for spark at the plug
1.If you have spark at the plug, but not starting - check that your carbs are getting gas.
2.Petcock Could be off, Fuel Filter could be clogged, Carbs could be dirty or clogged and your not getting any gas.
3.Pull spark plug - If no gas present then your not getting gas, if wet then you getting gas and your flooded. Make sure you have good gasoline, Bad gas won't burn.
or your bike is worn out and dont have any compression.

With Good gas, and Good Spark, and Good compresssion, the bike will run.

If your not getting gas to your motor through the carbs, pull carb off and thouroughly clean it.

To begin with you need a good battery @ 12Volts.
Check if there is spark at the spark plugs.remove one spark plug and earth it (spark plug body) and crank start and observe for the spark.
Check if fuel ( gas ) gets into the combustion chamber.
Try cranking it and thn remove the spark plugs and check if they are wet with gas.
Basically these are two things to check first.
Hope this helps!,
Let me know of the outcome and hope to be of help further..Thks.

Lets start slowly on this.

You have gas and the valve is on? Gas is fresh?

You have a battery and it is charged?

Plugs are firing? (No? check points - condenser - coil)

Are the plugs wet? (too much gas)

If dry, shoot some gas into the combustion chamber. Try again

If no electrical system, is your mag putting out? (got a spark)

Is the spark occuring at the right time? Engine out of time - time it.

If you have spark at the right time (good plugs) and fresh gas - it has to start

You might have a carb problem - but unless you have messed with them/it, and it has run previously, I doubt this.

Let me know if this is of any help

a

it's not that your not gettin gas it's that the gas is not getting thru the carbs to the engine. your bike will probably start w/choke on and then die, your jets are clogged and happens to most bikes that are stored w/gas in the carbs.,,,clean them if you know how or take it to a trusted mech...good luck to you...Tim

I had the same bike for 3 years and it wouldn't start when it was too cold outside under--about 33-37 degreese--it wont start.
---how cold is it where your trying to start it--

i know this bike like the back of my hand

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

Okay, let's have a look at it. Say Ahaaa.
The probable cause of the problem is not the spark. Get a fresh set of Stock NGK spark plugs, ground the plus to the engine, and check each cylinder for spark as the starter button is pressed for 3 seconds or so. I will wager that the spark is present.

The likely problem is the fresh gas was put into a very rusty gas tank. Bits of rust now inhabit your carb and are having fun plugging up the carb. Look at the gas valve. With a little luck there is a small bowl behind the valve. Remove it and tell me what you see in the bowl.

First thing > install a new set of the stock NGK spark plugs for your bike. Check for spark before installing. If no spark, then check to be sure the battery wires are clean and tight. Is the kill switch on? Is the side stand up? It should be up when starting. Is the bike in neutral? Check the fuses. Check the wiring connections, are they tight?

If spark is present, is the gas turned on? Clean or replace the air filter. If the bike still will not start go ahead and drain the carbs. There should be a screw on the lower side of each carb float bowl. Remove the screw then replace it after the fuel drains. Turn the gas back on and wait a minute for the carbs to fill with gas. If the bike doesn't start properly then shut off the gas and remove the carburetors from the engine.

For both carbs > remove the float bowl and clean the entire carb with a spray carb cleaner from the auto parts store. Wear protective goggles to avoid getting spray in your eyes. Spray all the little airways and fittings in the carb. Remove the two screws on the outside throat of the carb and spray into the screw holes as well.

Be sure to put these two screws back in the same hole they came out of. IMPORTANT > do not tighten these two screws down. Only screw these in until they LIGHTLY seat. Now turn each screw one and one half turns outward. Put the rest of the carb back together. Remount the carbs.

Next, remove the water trap bowl at the bottom of the petcock, (gas valve). Dump it, clean it and re-mount it, ( not all bikes have a water trap bowl ). Turn the gas back on to let the float bowls fill then start the engine. Be sure to balance and sync the carbs when finished. If you don't know how to balance and sync the carbs, get back to me after you do the stuff mentioned above. This process should get you back on the road.
