Okey, I have problems whit my NSR..

- tachometer not work.
- plug not give strong spark.
- Exhaust power valve not work 100%.

Speedmeter is ok, but RPM meter is dead. Also thermometer shows over to red. Any helps?

Second: Plug quits give a spark, like a lightning bright sky. Ignition coil is dead? Plug gives spark like a every 10 sec, but spark is very very weak..
Edit: Voltage is ~5 Volts before ig. coil.. I try to change black box but that not work.

Third: In accelerate rpm's "stops" 8000 about 3 second, after that valve opens and then lets go's..

bad English i'm sorry. Thanks =)
