If your changing to Pads and not putting the old ones back in, use WD40 on the pin and let it soak in. I normally rotate the pin with some plyers and then work it's way out. Make sure you soak the pin with WD40 and let it sit for aa fir while so it has time to soak in

Sounds the pilot passages and or the needl jet air passages are blocked on the carb for that cylinder that is not fireing. The carb should be removed from the bike and disassembled and dipped in carb cleaner. What I think works best for cleaning carb is Yamaha's Carb Dip I mix it 50/50 with warm water. All the rubber parts must be removed as they will be swell and be damaged by the dip. After you dip the carb will need to verify all passages with spray carb clean to make sure the fluid will make it through the intended passage.

I'm assuming that it has been sitting for a while and now it's stuck. Do you have oil in the reservoir? Pressing the brake lever should be able to force the piston out with no problems. Otherwise, try to get the seal out from around the piston, and spray some anti rust lubricant and let it soak.

Check all of your vacuum lines. Check your fuel hose routing. Check for leaks between carb and cylinders (intake boots).
Run some Seafoam through the tank.

Hi, Anthony I would really love to help you but due to the magnitude of yesterday's solar flare the batteries in my crystal ball are dead and my mental telepathy headset circuitry was melted. I need the year and engine size of your bike and a more specific definition of "trouble" please click on the word "COMMENT" below and provide this information in the box that will open and then click on the green comment box in the bottom right-hand corner after it posts I will receive an "ALERT" icon that will allow me to respond to your information.

Hi, Anthony if your bike has been sitting idle for months or years and you did not do any pre-storage maintenance I feel your pain it will probably have a dead battery and not want to start or if it starts it will idle and run poorly then stall, here are the following steps necessary to complete in order to get your bike back to an acceptable running condition.
1. If your battery was 2-3 years old when you last had the bike running you should replace it.
2. If you believe your battery might still be serviceable remove it from the bike and put it on a 1 or 2 amp trickle charger for 24 hours. If it is the old lead acid type with visible cells and acid levels fill each cell to the top line with distilled water and replace the caps, run the vent tube into a plastic or styrofoam cup, any cells that are cloudy/milky replace the battery.
3. After charging remove the leads and let the battery sit for a couple of hours then check the battery voltage with a volt meter, you should have 12.5 volts or better, any readings in the 11 volt range you need to do a proper load test on the battery and replace as necessary, any readings in the 10 volt range you have a dead cell and the battery needs to be replaced.
4. Drain and flush fuel tank, google " how to clean a motorcycle gas tank" find a couple forums to view the different options available.
5. Remove and inspect your air cleaner paper elements that are not oil soaked can be cleaned with a soft brush and low pressure compressed air, oil soaked elements must be replaced. Gause mesh and foam elements can be cleaned by soaking them in a container big enough to completely cover them with a solution of 1 gallon of water and 1 oz. of Dawn dishwashing liquid for small and medium size elements, for monster size double the formula and let soak for at least one hour then rinse with warm water shake off excess and let air dry, "WARNING" do not use compressed air as this will embed micro-sized dirt and road grime and destroy the mesh pattern and stretch foam elements out of shape just squeeze it like a sponge and let air dry, use a fan if you're in a hurry. When completely dry spray a very fine mist of air filter oil evenly around the whole element.
6. Remove the carburetors, disassemble and decontaminate with a carb dip or if you have EFI remove injectors and clean with carb spray and compressed air
7. Remove fuel valve and filter disassemble and clean as necessary, remove, clean, and inspect fuel and vacuum lines and replace as necessary.
8. Replace spark plugs with new ones and check for spark.

Hi, Laz and the usual suspects are:
1. Ignition Switch not in the "ON" position.
2. Engine Run Switch in the "OFF" position.
3. Discharged battery, needs to be 12.5 volts or better and be able to pass a load test if necessary.
4. Check the battery terminals for damage or corrosion check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
5. Tip over sensor needs a reset.
6. Faulty ignition switch.
7. Faulty starter button.
8. Faulty kickstand or clutch pull in switch/sensor.
9. Starter control circuit, relay, or solenoid faulty.
10. Main fuse or circuit breaker may be blown or faulty.
11. Check for engine trouble codes.

Hi Anonymous, if your headlight is not working, keeps burning out or is dim the first thing you need to check is the headlight bulb for damaged filaments then check your light circuit fuse, that being said the usual suspects are:
1. Faulty ground or power supply wire to headlight bulb socket.
2. Worn, chaffed, or broken wires in the light circuit.
3. Corroded, broken, or loose pins/sockets in wire connectors.
4. Faulty hi/lo beam switch.
5. Faulty ignition switch.
6. Fuse is good but no continuity on both sides.
7. Faulty wiring between battery positive and headlight bulb socket.
8. Weak charging alternator/generator.
9. Faulty voltage regulator/rectifier, overcharging.
For more information about your issue, please visit the websites below. Good luck and have nice a day.

sounds like a sticking float valve flooding in from carb

Suzuki GSF 1200... | Answered on Aug 14, 2015


Ok I have one of these.They are not water cooled so it's not steam from a leaky head gasket,it would by be oil unless it's bluey coloured smoke.if it was too rich ie choke stuck on or blocked air filter you would have black smoke.so I would say it's one of two things.you have either put some diesel in it as that smokes grey and fouls the plugs making it misfire and cut out or the small drain hole in the left hand side of the fuel filler cap well has blocked up and you do have water in the fuel.drain the carbs via the drain screws on the bottom of the float bowls and catch it in something,if there is water in it it looks like jelly in the petrol.Ok good luck ps that's a man's bike.;0)

Yes because they are only there to counterbalance the weight of the piston and diaphragm.

Suzuki GSF 1200... | Answered on Oct 06, 2014


Check for loose battery connections or corroded connections. Check also for a loose ground wire to frame or engine block. If they all seems fine make sure your battery is fully charged and if so check fuses. Think simple first then go up the line for bigger problems. Hope this helps.

Sounds like an oil pump issue. Can you hook up a pressure gauge to find out how much you have at idle vs with throttle? Probably not a real problem but you might want to replace it anyway. Obvious question here, check oil level?
