dont know whats goin on with my bike but sometimes when riding my bike when go to extreme low idle and as soon as I hold the clutch it turns off, than after trying to turn it back on it takes me a long time of trying than it turns on and rides fine and sometimes after trying a long time of trying to turn it on it will turn on than shut off and repeatedly till I rev it up high than it stays on? Any suggestions ty

 

Check the battery voltage at idle & also revved up to 3k or so RPM. It should be over 13v minimum at idle and 14-14.5 revved up a bit. It sounds like your stator and/or voltage regulator are failing and the voltage is dropping at idle. When it drops too far the ignition system doesn't work properly or shuts off altogether.

There are other possible causes also such as a carb issue, but this is the easiest to check and a common problem on the CBR.

 

but its not when I'm idling ill be driving( giving it gas) and it will just stop wanting to give gas and when i touch the clutch it turns off on me

 

One common cause of intermittent running problems in the past has been a loose connection. Check for tightness at both battery terminals and also the ground point at the frame.

 

Tks I'll check on that guys

 

past few days my bike turn off when I try start run, and sometimes don't start again

After 1h try run I found it!!! In my case the problem it has very simple, a broken cable on right hand bar (engine cut out). Then I turned the wheel to left/right the cable lost connection and the bike turn off, I fix the cable and no more problems!!!

Start your bike and touch on that cables to see if your engine turn off when you move the cables, good luck

Sorry for some mistakes in my english
