Hi guys and gals I'm a newbie here and to riding only been riding 10 months aged 39 first bike k8 Gsxr limited edition max candy orange and black, I absolutely love it she is my baby lol, bikes not been started for 2 months so get to bike turn on and she is flat as a dab tried bumping her but no good, so I removed the battery and slow charged it, returned to bike fitted battery all great put in key turn on all ok but notice f1 and key light flashing bike turns over but won't start, it's as if the bike can't see the key/chip any advice would be great, I did check dealer code and comes up as c42 = ignition
