Diconecting the power valve on a 91 fzr 1000

Hi, Lewis reconnect the power valve and the usual suspects are:
1. Severely drained or faulty battery.
2. Faulty regulator/rectifier or high output coil.
3. Faulty power valve, solenoid or installation.
4. Clogged air filter or exhaust.
5. Cracked or incorrect float level.
6. Float needle is not seating.
7. Faulty reed valve.

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.

Just bought 1989 fzr 600 wont start been told battery drains when running.spark is orange,on test help

Hi, Paulheywood3 and the usual suspects are:
1. Fuel tank empty.
2. Fuel supply valve/petcock turned off.
3. Fouled spark plugs.
4. Engine flooded as a result of overuse of the enricher.
5. Vacuum hose to the fuel supply valve/petcock disconnected, broken, cracked, or pinched.
6. Fuel valve/petcock or filter clogged.
7. Severely discharged or damaged battery, you need 12.5 volts or better and be able to pass a load test if necessary.
8. Check 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.
9. Loose or corroded wire connection at the coil, battery or plug between ignition sensor and module.
10.. Spark plug cables in bad condition and shorting, cable connections loose, or connected to the wrong cylinders.
11. Ignition timing incorrect due to a faulty ignition coil, ignition module or sensors (MAP, CMP, CKP, O2, TPS, ETP, IAC,or BAS).
12. Faulty neutral, clutch lever, or kickstand safety switch.
13. Faulty fuel pump fuse or relay.
14. Security alarm needs a reset.

My 2001 yamaha r6 keeps draining all the water out of batteries ive replaced stator and voltage regulator

is battery more than two years old? if yes replace battery. Battery voltage should be >12.4 volts minimum. if it wont hold this charge its bad. Check all the wiring on your bike to make sure that you dont have a shorted system that is draining down you battery.

Wont start

Basically there are these two issues tht would make the bike wont start..1 is tht if there is no fuel going into the combustion chamber and 2 if there is no sparks at the plugs.
Guess you will haveto check for both of these.
Good luck.
