SOURCE: gsxr 750 slingshot, fuel problem?

The slingshot does NOT have a fuel pump. It is gravity feed through a petcock. Make sure that the petcock is set to the ON position. Its under the tank on the side.
If your bike has K&N filters on the carbs make sure you cover them with a plastic back before you wash next time.plus you will have to wash them and re-oil them before you put them back on. Dont use super high pressure washer to wash your bike. A garden hose will do.
If it has the stock air filter you might have gotten water into the carboration system with that high pressure washer you used. You'll need to disassemble the airfilter unit and either remove your carbs to take off the float bowls and get the water out or try to drain your float bowls while the carbs are still on the bike. Siphon out all the old gas if you think you got water in it or you will have to do this all over again. Sounds like you intoduce water into the system to me.
1. Got good gas?
2. Got spark?
3. Got oxygen?
4. Got rid of water in the system? = Should start.
I use to own a sling shot too. 1988 model red and white.

SOURCE: GSXR 750 Slingshot does not start

best way to do this is to take spark plugs out individually and check for smell and sight of fuel. if it is getting fuel but not sparking then you will have a wet sparkplug. if it is dry look at the colour of the hook at the bottom of the plugs. brown plugs means running too rich, grey plugs means average burning and working well. black plugs is very bad and must be serviced. if all this not working the other test you can try but dont spill any petrol before you do this. if while you have plug out(only one at a tim or yuoll loose where wot leasd went to where) plugging it into the cable and holding with a very insulated pair of pliers, then try to turn bike over(start) whilst looking at the hook bit on the plug. if you see a bright spark from the plug then you will prob find they firing in the worng order. this could be a problem and should be dealt with by a dealer.

Clean the air filter and, if you have one, remove the water trap bowl on the fuel petcock and clean it. How good is the battery? Install new STOCK plugs. Bear in mind it may be time for carb kits. Other than your cleaning the carbs, the carb kits and balancing and synchronizing of the carbs are best left for the shop to do.

Check the exhaust pipes. If there is a restriction in the burned gases exiting the tailpipe then the bike will not run right, will loose power and even die if too much back pressure builds up. Disconnect the exhaust system and tick off the neighbors with a quick ride around the block without a muffler. If the engine still dies then exhaust is not likely to be the problem.

Check the compression on all cylinders. Depending on the compression, the bike may be ready for a valve job. If you pull the head for the valve job then you might as well consider re-boring the cylinders and install new pistons and rings. Bear in mind, doing a valve job and / or pistons is not recommended for the novice. The good part is that when the work is finished you will effectively have a new engine.

SOURCE: My 06 gsxr 750 will not start. New battery,

if the bike will not turn over you mean it doesnt crank? because if it doesnt crank over then its a starter issue and could be a simple as a blow fuse, but then why did the fuse blow? ( starter going bad)..... or it could be the starter solenoid itself, and this is where i believe you might find the fuse. response feedback appreciated.

2002 honda civic turns over but won't start; not fuel pump or timing belt


Not to sound sarcastic, but I would start with a different mechanic.
Diagnosing a no-start situation requires a basic list of possible causes which we eliminate. You start with spark and fuel and go down the list.
If it has spark, fuel, and compression, it should start. It has to be missing one of the three elements.
It takes time to check every component and go down the list, but that is how its done. You have to check the components one by one.
So, does it have fuel pressure to the injectors?
Does it have spark to the plugs ?
Is the cam timing correct ?
Are the plugs fuel fouled ? Can you spray starting fluid into the intake and get the engine to try to start ?
Has anyone checked the computer for trouble codes ?
Does the engine sound like it has normal compression?

My 2002 Chevy Blazer won't start?


If you replaced the injector after the plugsthey may be fuel fouled.Pull the plugs and clean them.(you can sandblast them,or use a method I used to use-shoot a little starting fluid on them and use a lighter to burn off the contamination of too much fuel).I can't believe GM kept using this stupid design so long-I remember nearly new Vortec V6s with this same problem in the '90s.

As you have probably figured out by now, you will have to treat it as a no start and troubleshoot it when it fails to start. Until you figure out if you are loosing spark or fuel to the injectors when the engine dies you have no direction to go in.

GSXR 600 K1 Won't start tries to fire up and the exhaust pops but that's all


Based off of the limited information, the solutions are going to be generalized.

Visually check your battery for any acid build up. If you spot any, obviously some acid remove would be called for. Acid can sap a battery's output to a starter.

Visually inspect fuel components. Fuel injectors on bikes tend to get clogged when they sit for a while. Especially on older models. Refer to a repair guide for your specific model for guidance on the procedure to inspect fuel injectors.

Those two common starting problems for bikes. Without more information it is hard to offer a specific solution.

I have a Suzuki GSX-R 750 and my F1 one light has started to come on when I excelerate some speed what does that mean.


Odds are its your SET valve needing adjustment, have the codes pull on the bike. If it is the SET, you can remove the SET system easily or you can have it adjusted.

If you get a code.

The codes are as follows:
C14 - THROTTLE POSITION SENSOR
C15 - ENGINE COOLANT TEMPERATURE SENSOR
C21 - INTAKE AIR TEMPERATURE SENSOR
C22 - ATMOSPHERIC PRESSURE SENSOR
C23 - TIP OVER SENSOR
C24 - IGNITION SIGNAL #1
C25 - IGNITION SIGNAL #2
C26 - IGNITION SIGNAL #3
C27 - IGNITION SIGNAL #4
C28 - SECONDARY THROTTLE VALVE ACTUATOR
C29 - SECONDARY THROTTLE POSITION SENSOR
C30 - SECONDARY THROTTLE CONTROL UNIT
C31 - GEAR POSITION SENSOR
C32 - INJECTOR SIGNAL #1
C33 - INJECTOR SIGNAL #2
C34 - INJECTOR SIGNAL #3
C35 - INJECTOR SIGNAL #4
C41 - FUEL PUMP CONTROL SYSTEM
C42 - IGNITION SWITCH SIGNAL
C46 - EXHAUST CONTROL VALVE ACTUATOR
C00 - NO FAULT

1990 GSXR 750 L, fuel smell when running. has 1100 jets in the carbs(apparently!) Is there an easy solution?


Short answer no, it is most likely running too rich & will need to pull the carbs & replace the oversize jets with, either the factory jets or smaller ones.
