20 Most Recent 1993 Suzuki GSX 750 F (Katana) Questions & Answers

If it has been laid up for over a month , I would drain the carburettors... I this doesn't help, drain the gas & fill up with new gas !

Go to http://www.alpha-sports.com/suzuki_parts.htm, search the year of your bike, find your bike and then open the wiring diagram that will be available

The clutch switch circuit is a yellow wire with a green stripe. The handlebar switch has 2 male bullet type connectors that will pulg into female connectors of the same color. One will be on the harness from the r/h handle switch and I believe the other is on the main harness, r/h side of bike under fuel tank. It dosent matter which goes to which just mate male to female.

if you follow the positive cable from the battery it will lead you to the starter solenoid. it's jast a little square that also holds the main fuse. you can check if it's bad just by bridging the to posts together with a set of needle nose pliers. if pushing the start button just makes it click when you bridge it it should activate the starter. if the starter works when you bridge it, you know the solenoid is bad. if your stater still clicks when you bridge it, make sure your battery is at full charge. if your battery is at full charge and it still clicks, your starter is bad.

Well that cant be good.
Do you notice any puddles or smell of fuel when the bike is sitting?
Is it on just one leg of your jeans or both?
Do you have the stock air filter installed?

I would look for leaks in the seam of the tank or leaks in the fuel pipes that run between the carbs or a leak in the petcock/ fuel line. Its gotta be leaking somewhere, or its shooting fuel out the throat of the carb when its running which could indicate valve problems.

Take the fairings off so you can see and let the bike sit and run at idle. With a battery powered flashlight check the bike over closely until you find the leak. Wipe everything off dry and check again so you are sure where it is coming from. Then ( with the air box removed) rev the motor while looking with the flashlight and see if ti shoots fuel out one of the carb throats. Dry everything off and double check again.

Hi, Check coil or ignition module. replace it. Good luck.

If your starter will not stop turning over then your starter solenoid contact bar is stuck in the closed position. It should only close when you hit the starter button. With the solenoid out of the bike check the solenoid battery terminals for continuity. If there is continuity across the large terminals, replace the starter solenoid

The banging sound in the engine is Pre-ignition aka engine knock and detonation. This is BIG TIME BAD for the motor. It can destroy a crankshaft and piston in no time. And once it punches a hole in the top of the piston then little metal filings run through the entire lubrication system screwing up bearings and the like.

A lot is involved so the best thing is for you to download a service manual and a parts fiche. The manual can give you all the info available on the oil cooling and lubrication system. The parts fiche is a handy aid in parts identification and unit construction. Free manuals can be downloaded at the site below. Yours is 42nd from the bottom of the Suzuki list. The two files are next to each other.

Please rate this answer. Thanks chirker!

You have to take the bike back to suzuki for them to fix it for you.

This is from a factory manual, please rate my answer. Thanks >>>

vapor lock? float level ? main needles to low

Just make the bike level and check it. It's actually better to check it after the engine has been off for ten minutes or so. This ensures that the oil has had time to drain back into the pan and is not circulating elsewhere in the system. That will help with obtaining an accurate reading

When too much fuel is being supplied to the carburetors the engine is flooded. When you remove the spark plugs it allows the fuel to dissipate enough to allow the engine to run again. Drilling out the jets is not an accurate/preferred method for changing the jet size. Most of the time the jets end up being drilled too big. You can save money by just buying main jets. A jet kit usually will come with the slide needles made with a different taper from the stock needles. You may need to break down and buy a jet kit or a least replace the main jets with accurately sized main jets (not drilled out jets). In other words your main jets are just too big.

Pull the clutch lever and block the actuator arm so that it cannot release (the one on the transmission, not the handlebars).

As you let off the lever, you can fish a small screwdriver in there to get the zinc ball out of the lever. You have to align the adjusters on the lever so that you can remove the cable. The adjusters stay in the lever.

Once you've done that part, just follow the cable back to the clutch actuator arm, and remove the cable and zinc lug through the hole in the arm.

that is the tank breather tube

bulb front or rear would cause same smptom. Flasher located under seat or side cover

Hi and welcome to FixYa,

To determine if fuel is entering the combustion chamber, place back the spark plugs without the wires. Start and remove the spark plug again. They would be wet with fuel.

Additionally, loosen the drain screws at the bottom of the carb's bowls. Collect the draining fuel from the drain hose individually. Compare quality and quantity while noting for presence of sand, dirt, rust, water or any other contaminants.

Starter fluid maybe used.

Good luck and thank you for asking FixYa.

Hi and welcome to FixYa,

Offhand, it would appear neither. Your description indicates that the idle circuit of the carbs needs looking into more particularly the slow (idle) jets. Almost always, this requires a carb pulldown, cleaning, soaking of non-rubber parts, passageway clearing and jets inspection.

Still, it is of course very possible to have a restricted fuel delivery system hence the idle is severely affected. Since cleaning is the recommended approach, might as well extend all the way to the tank.

Good luck and thank you for asking FixYa.
