Top 20 2007 Suzuki GSX-R 750 Questions & Answers

lights fail from a fluctuation power supply when a ground wire is loose or the bulbs are loose in the holders the resultant problem is arcing which burns out bulbs as the current increases as the resistance drops the voltage

It sounds like your cluch pads are gone

It sounds like its possibly a bad regulator/rectifier. I have posted a link to a video on how to test your regulator. How to test 2 plug Regulator Rectifier for K6 K7 GSXR 750 600 1000

Sounds like a hot wire in the signal circuit is grounding somewhere.

Sounds like you have a broken timing chain

Back wheel or is it a engine bearing

Maybe a bulb?

Hi check the kill switch, fuses is there any lights on the dash

kickstand kill switch. disengage it by cutting the 2 wires then connect them together and tape up or solder and tape up then just remove the switch from the kickstand

This will likely be one of two problems1....Your battery , even if it is showing 12 volts may be bad and not giving you the necessary cranking amps to fully engage the starter and turn the motor over2....Due to getting wet your wiring is corroded and needs to be cleaned, especially the ground, and then remounted tight.Try these and see if it helps

even though the battery is charged it could still be bad and giving enough cranking AMPS. to engage the starter, try borrowing a good battery and trying it, if it woeks taht is your problem

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

you have to check all your wiring for broken, bare or loose wires. you may have to get your dad or someone else to help test them if you can't find a visual problem as sometimes they will stretch and break inside the plastic coating which will only be found doing a continuity check.
hope this helps

Sounds like the kickstand safety switch is not making contact. There is a plunger type switch that the kickstand pushes when it is in the up position. The switch makes contact allowing the ignition system to operate. The switch is bypassed when the bike is in neutral, allowing you to start the engine. However, if the kickstand switch is not engaged when the bike is taken out of neutral, it acts the same as the kill switch on your handlebar. Some of these switches have adjustments and that may be all that is necessary. In a pinch, you can short the switch out (taking the two leads that go to it and twist them together) bypassing the safety circuit.

The F1 light is really Fi, Fuel Injection. The fuel injection sensors have detected a problem in the system. Major problems will not let the bike start. You will need to get the bike to a dealer so they can hook up a code reader. The reader will pin point what the problem is. Once you know the source of the problem you can then decide if you can fix it or if it is time for the dealer to service the bike. Please rate my answer. Thanks!

In most cases, if all those lights have stopped working at the same time, you have blown the "lights" fuse.
Replace the fuse, and check again. It should fix you right up replacing the fuse.

Recheck the battery conections, undoing them clean them and then replace them, it may be that when you put the battery on charge if you didnot remove it from the bike you may have blown the main fuse, this is not the fuse located in the fuse box, it is the fuse located at the starter solenoide, follow the poss red wire from the battery to the solenoide, here you will find where the wires attach to the solenoide, a fuse located under a plastic cover, supplys ignition power, i trust you have done a thorough test on the battery. ?

The check oil light might be becuse of low oil or you need to service it but you could have a bad spark plug

if you have a fuel feed to the injectors (take the feed pipe off the injector rail / throttle body, and turn ignition on and off v-quickly, fuel should come out very quickly)
if you have a spark (remove a coil / ht lead, put a spare spark plug into it, rest onto metal surface (block/head is good) and crank over, you are looking for a bright blue spark that is frequent)
if you have both of these then it should start (unless there is too much / insufficient air flow into the firing chamber- check air filter is correctly fitted and clean)
hope this helps
