Bike back fires and the f1 light comes on on the cluster panel as well as bike dies

All questions need FULL 'year make model' as the first 3 words in all questions, or we guess.

The FI light is the equivalent of a CEL in your car. The ECU has detected an abnormality with one of the sensors, check the code and see what's up. Yes what he said...you will need a service manual to guide you through it.

F1 is no fault. put into dealer mode the little white connector under the rear seat, a bit of wire bridge the terminals and a fault code will come up, if you put a retarder on the bike try putting back to std

You have an electrical system fault and probable a falt bettery as well.

f1 is just telling you that there is a fault, to get the fault code you need to locate a two wire capped off connector(cap may be missing) this i think is on left side of bike in line with rear peg and just under the trim(seat) use a paper clip pushed ito the connectors to join the two wires, turn on the ignition but DONT START THE BIKE you will now see a fault code on the dash ie c34 etc this tells you the fault itself. get back to me with this and i can help further

f1 is the fault code light....just make sure the battery termianls are done up tight on the battery....

The FI light is letting you know there is a problem with the Fuel Injection system on the bike. You will most likely need to take it to the dealer and have them diagnose it with their computer. You can check your fuses and make sure they are intact, but most likely dealership problem.

Try downloading the service manual here and make the ECU to turn into diagnostic mode and it will blink you the right code.Then according to the table with the codes you can see what sensor fails

Needles stuck indicative of instrument cluster complete failure. Cause unknown. This is second instrument cluster that has failed on this bike, first one failed at about 3000 miles, twenty-two months ago. This "new" one died in mid May 2008. Received word from Ducati North America that they will accept the warranty claim for the toasted instrument cluster!!! Am still concerned about cause...this is second instrument cluster for this S2R800. Seems to be an issue prevalent on some of these late model Monsters. Will update more after instrument cluster gets in and replaced by Bloodworth Ducati in Nashville.
