Question about 1990 Yamaha FZR 1000
It wont rev after ive disconnected the power valve
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

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.

Testimonial: "thanks very helpful"
SOURCE: Fzr 250 Wont rev when cold
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....
