Check Engine Light comes on in the rain???

My check engine light seems to always come on during the rain, It drys out and goes out??? 500 miles ago I took off my fuel emissions canister off the side of my bike, could that be it? Should I be worried? Does anyone have any ideas as to what's up?


Thanks for any help that you can give me

Mine started doing the same after the 1st time i got caught in the rain @ 600mls.

In my case it was the exhaust flapper valve sticking. My dealer lubed the cable and valve during it's service and it hasn't happened since.

There's some good info on this in the Multistrada bit of this forum.

Good luck.:)

Or you could just detach the exhaust servo cable from the flapper and be done with it...with the cable detached the flapper will remain in the open position. This is a simple 5 minute operation.

Excuse me as I am new to Ducati; but I think that will cause your CEL to come on?
If you unplug the electrical connection to the servo you'll get a CEL, if you detach the cable at the exhaust valve there will be no CEL as the computer dosen't know that the cable is not hooked up...the servo will operate as normal, but the valve will not operate. Note: it is still possible to get a CEL if the servo is bad, in which case you can have it replaced under warranty...or remove it and go with the duc.ee to prevent a CEL, or have your ecu reflashed and have the exhaust servo taken out of the equation.
