Just a thort but have you tried spraying the air sensor in the right-hand-side air intake with WD40 or damp start?  

By Scotty on Tuesday, September 24, 2002 - 04:52 am:

Had the bike been washed or ridden in rain prior to when you got the flashing EFI warning?

If so then I wouldn't worry cause they all do that as Mr CRMC33 says its that air sensor getting damp/wet that causes the EFI warning.

Mine has done it on a number of occations over the last 16 or so months of ownership if the sensor has been exposed to any water.

Here's a list of the Fault codes:

If you are getting a -1, 0, or 1 that simply means that your throttle position sensor is loose, properly adjusted, or tight, respectively.

I agree with Scotty - If the EFI warning only comes out after washing, look at the wiring harness to see what may have gotten wet. Maybe spray it down with a little sealant or hit the offending connector with a shot of waterproof lube.

i have noticed that a wet air sensor can be temporarily solved by removing the clutch safety switch from its mount by the clutch lever. the bike then starts acting normal. once the senso has dired, the switch an be placed back in its mount.

Hey Splyn, never heard that one before!

What does a clutch switch have to do with an air sensor? Is it an Italian thing again? Has Luigi (the one with the hammer for the exhaust dent) got some wires crossed?

apparently if you remove the airbox, the rev counter speeds up too
