My bike runs fine in the dry or cold however once there is a heavy down poor of rain I'll be sat at some lights and the bike will just die and then takes about 2 minutes before i can try to restart her.

Also occurrs when washing the bike. I'm guessing its some form of electrical fault but not sure which part could be causing it, it only had a service last month and spark plug replaced.

Anyone else had this problem?

thanks

I would start looking at main ECU,remove seat and left side plastic cover there you will find the ecu remove the connectors plugs and check for no water damage also make sure the rubber seal is in the connectors plug

Thanks for the info strangely enough did occurr when washing right hand side. Wat sort/size rubbers required presume they don't need to be from yam being awkward sizes etc

It does sound electrical.

I had something like this on my XTR, found out that the kill switch wire broke at the connector under the LHS of the tank. Once the mechanic found the problem and fixed it he suggested the same as Kev said for all the rest of the connectors as there is quiet a few on the LHS of the bike. Also the same for any of the connectors at the rear of the bike on both Right and Left hand side of the bike.

I'm convinced its electrical going to look at all of the bike diagrams an see whats wat. Think that will shed some light.

Failing that I'll buy a water pistol and squirt individual wires lol

The funny thing is initially I said it off the fly however thinking about it may actually prove useful
