It seems likely that your fuel pump is not operating, you should hear the fuel pump priming when you turn on the ignition, if not the fuel pump is at fault, this is not uncommon and a replacement is the answer.

I'm not sure about yamaha but suzuki has a vacuum connection on the fuel petcock that turns off the fuel flow if there's no vacuum from a running engine. check that all connections to the petcock are secure, the vacuum line should go back to the carbs. If you put the petcock in pri(me) it defeats that and the bike should run but the carbs will flood if you leave it for any length of time

Can you bypass the fuel pump so the carbs are gravity feed


Would not recommend. Replace the pump if it is not operating properly, with a pump that is oem equivalent.

1991 yamaha fzr 1000 it has sat for 2 years. i bout it as a project bike. i have drained the gas tank and cleaned it. when i try to start it it tries but wont start. i dont know where else to turn or what...


Hi, Rossi_thomas 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, 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 replace the battery.
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 your air cleaner and clean and re-oil per Mfg. specifications.
6. Remove the carburetor, 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 fuel lines and replace with new ones.
8. Replace spark plug with a new one and check for spark.

My bike wont start and soon as i turn the engine run switch i hear something under my seat start clicking what is that??


Its probably your starter relay or possible your fuel pump starving for fuel... the starter relay is under your seat behind the battery and the fuel pump is under your tank...

Your fuel tank breather is blocked. As the fuel is sucked out of the tank a partial vacuum is built up and no more fuel can come out.
Check the breather holes in the filler cap or the breather pipe if it has one.

Should be only about 2-6 lbs. It has a fuel pump, but with carbs, it needs to be very low.
