I have this problem with my CBR 600RR from 2005. Whenever i get it from neutral to 1st gear, the revs go so high(sometimes to 4000-5000r/s), and when i switch back to neutral or i hold the clutch they go down... It's been giving me a great headake and risk on circle wheelies, so any of you guys could help me ?

So the bike revs outa nowhere?

Not exactly outta nowhere. Only if i rotate the idle to 4000rpm and i open the throttle, after i decelerate it is late in coming back to 4000. instead it stays to about 5000 and gets back very slowly to what it used to be.Does that make sense?

Disconnecting the speedo should solve your problem....

I' ve just read that was very helpful. But what happens if i only disconnect the pink wire from the ECU and i leave the original speedometer connected like before? Will the speedometer still show me the temperature,oil, gas etc? or it will be dead?
