You can hear the fuel pump, so it and its relay are  okay.

So is it getting spark? You could pull the plugs and see if they're  

The rain relationship is a clue to  a known problem with the early R11 
models. If you want to test it quick and  dirty, just turn on the key and put the 
bike in fifth gear. You will hear the  fuel pump run when the key is turned on, 
then stop. Now turn the rear wheel in  the normal direction of rotation. The 
fuel pump should start again when the  ignition trigger sends an "engine 
rotating" impulse to the Motronic computer. If  it does not, you have located the 
trouble to the ignition trigger and saved a  lot of potentially dangerous 

For instance,  pulling the plugs to test spark can EASILY lead to total 
ignition system  failure, because there are no good grounds within reach of the 
plug wires. All  the exposed bits are painted. If you fire the plug without the 
plug properly  grounded, that spark will travel SOMEWHERE to find a ground. If 
that somewhere  is up in the ignition circuit of the Motronic, it will take 
out the  brain.
