F1 error

I went to ride the wee strom (08) to work today. it has been in the garage for the last 2 weeks since I rode it last. I have been on my sunny weather bike. My last trip was about 500 km in very wet weather.
Turned the key on and it made its normal noises but they did not stop. F1 appeared on the dash where the clock normally appears.
Anyone able to tell me what this means?

Search for dealer mode for your model bike on this site or through Google. Once followed the procedure and have placed into dealer mode, a code should be displayed on gauges (clock display area). Look up the code in your owners manual or search for the codes on this site or through Google, to translate code to what has failed on your bike. Let the members know the outcome or if you need further assistance.

kevinc, the F1 means you need to go to dealer mode and let it give you a code. There are some helpful videos on YouTube about it, but the best help that I have seen is this page from VSRI. It is a rather good tutorial for walking through the procedure FAQ: Dealer Mode & FI Error Codes Hope that helps. Let us know what you find out.

Thanks for the info. So basically the F1 or FI indicates you have an error. After checking Youtube again I found the fellow calls himself Dr.Vstrom is great for info on service.
He shows how to put the bike into diagnostic mode to see what the error is. It is very simple and easy once you know. A paper clip to switch it over then turn the key on.
For those that know about reading the automotive "code readers" this is a built in reader. The video lists what the codes mean.
My bike I guess it was a glitch as I have no ERROR showing. My reader says -C 00 which is the all good code.
Here is a link to the video;

User Mode (normal running mode)::| if an FI error occurs you will see the "FI" letters displayed in the odometer readout area. If the FI is alternated every 2 seconds with odometer readout & the Red FI lamp on the dash is on solid, the bike will start and run in fail-safe mode. If the odometer readout is FI & the Red FI light lamp is blinking, the bike will not start.

Dealer Mode::| An FI error will be memorized in the ECU when an error is present. This error will stay in the ECU as long as power is not removed from (battery disconnected or ECU unplugged) the ECU and the error has not been cleared. It should be noted, that if an FI error is intermittent, the error code should be checked before the bike is turned off. Carry a spare key & a jumper so the seat can be removed and Dealer Mode entered while bike is still running. As soon as an error is cleared it is removed from ECU memory. You can run the bike as normal when in dealer mode.:| If you are dealing with an intermittent problem, wire it for dealer mode and ride. The code will show when the FI light is on. If the error clears, so will the code.

Dealer Mode Engine connector is under the left side cover behind the seat latch.:| Remove the connector cover to access the connections.:| It has a 6 pin plug with four wires.:| The White/Red & Black/White wires are the ones you will jumper to enable dealer mode.:| In the 6 pin plug they are the ones on the end.

The Dealer Mode ABS connector is located under the left rear fairing next to the ECU. The smaller one with a soft rubber cover is the dealer mode plug.
