I have just cleaned the bike and was checking things when I noticed that the break light did not stay on when the front lever was depressed. It just flashes on off. It works fine when the rear brake pedal is pressed. Any ideas? Thanks.
I would imagine that the microswitch in the lever is either on the limit of its adjustment or has water in it. You could try activating it with a small screwdriver or blowing it out with an airline.
