Question about 1990 Yamaha FZR 1000
Hi, Kdlesure 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 3 years or older 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.

Sounds like a loose wire in the battery box somewhere. Or even under the seat is where the wires run after leaving the battery box.

If the starter is turning your engine over fast enough, it's not the starter. If it's struggling to turn the engine over, it may indeed be the starter. With over a 100 thousand miles on the bike, I'd suspect the fuel filter would need to be changed. One other cause could be low compression. An engine with low compression requires the starter to turn the engine over longer and faster to get the engine to fire off. I call this "spinning the engine up" like a jet engine has to do. The RPM will increase as the starter spins it and eventually it'll fire. This would mean that it's time for a top end job including rings and a valve job. But, it could be something to do with the fuel injection system. I don't know anything about fuel injection. Sorry. But, I do know that it's supposed to sense the temperature of the engine somehow and enrichen the mixture when the engine is cold.
