G'day, I have an issue i am severely hoping someone can help with. A few months back my fireblade decided that whilst I was riding home from work, it would cut power under acceleration, so the moment i went to take off home from the lights - the engine cut out. It started again first go but as soon as i clicked it into gear and attempted to roll the throttle it died time and time again. Long story short i ended up having to push it 20km's home as it would start but wouldnt accelerate at all, the engine would just cut out. After some research, the dashboard indicator light suggested it was a MAF/MAP sensor (according to the user manual) replaced that but that made no difference at all (without a map/maf sensor bike wont start at all). More research suggested maybe plugs and coilpacks, so I checked those they looked almost brand new (only 12 months old but i replaced them anyways) - nada still no acceleration, Replaced injectors, fault still persists. Checked the fuel pump, pressure regulator, injector rail and the fuel filter, and everything looks fine (no leaks, sprays fuel when ignition is turned on/bike is started), no build up or restrictions that i can see. Im desperate! We dont have a bike mechanic in town at the moment so taking it to the "dealership" is unfortunately not an option. Any help would be appreciated!

 

Sounds like either a faulty TPS or disconnected/broken vacuum lines.

 

Awesome, Ive ordered a new TPS, Il give it a try - appreciate the reply.
