I have an 06CBR600rr I bought in pieces and the previous owner couldn’t get it going. The problems are. When you press the start button, it shuts down the tachometer, then it’ll reset. It’s acting as if the engine is seized. I pulled the clutch cover off and rotated it clockwise, also took the idler gear off and the starter jumps. It moves very easy and you can compression noise. I have replaced the brushes in the starter, stator and R/R and kill switch since it had broken wires. all fuses are okay.. at this point I’m pretty much stumped.. Not sure if the starter is just really weak, or ECU. Any feedback would be appreciated.
