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.

Have you checked if the EXUP valve is working? It should cycle when you turn the ignition on.
If it's stuck in the closed position it will be choking the engine in the way you describe

SOURCE: could you please tell me if a thunderace engine

It is NOT a direct bolt in by any means. If you have enough time money and talent, anything can be made to fit but if you are looking for something to bolt up and go, that is NOT it. TOTALLY different cases.

SOURCE: Fzr 250 Wont rev when cold

Hi!!
Firstly clean the air filter.
and then the carb too needs cleaning.
You can use a good fuel addative to clean the carbs.
There is a YESI a tube that runs upwards from after the carbarator ... if there is any kind of leak in this you will need to change it immediately..
An advice...Pls dont ty to fix any leak on this using any type of solution, it ALWAYS backfires....

Hi, Salvador20_m 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. Discharged battery, 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.
8. Loose or corroded wire connection at the coil, battery or plug between ignition sensor and module.
9. Spark plug cables in bad condition and shorting, cable connections loose, or connected to the wrong cylinders.
10. Ignition timing incorrect due to a faulty ignition coil, ignition module or sensors (MAP, CMP, CKP, O2 and/or BAS).
11. Security alarm needs a reset.

Lights get brighter when i raise the rpms on my yamaha fzr 1000. help??


Lights going brighter on reving generally means the battery is getting weak. Check the water in the battery. There should be enough to cover the top of the plates. When the engine revs the flywheel generates more electricity. The battery buffers the power. A weak battery does not buffer the extra power very well.

Please rate this solution. Thanks!
