Bike not starting! Help! CBR250RR!

Discussion in 'Technical and Troubleshooting Torque' started by WRCKLS, Aug 4, 2008.

  1. Hey guy's,

    My CBR250rr is not starting again. Last time i changed the all four sparkies, but no good. I've tried everything! Changed the spark plug's, checked all leads and coil pack's. It's kicking over but no initial follow through. Sometime's i get some mad back fire too. Can anyone shed some light on my situation, Or can point me in the direction of someone who know's their CBR's.


  2. When starting, does it splutter as if its about to fire up, or does it give no hint of ignition?

    No difference with choke or not? Tried it with part throttle open? Kill switch off? (been there done that :p).

    Try here also:

  3. Check for spark ...?
    Check fuel ..?
    then check for bad fuel / water contamination.
