I didn't know that DR600's had condensors as they have a CDI ignition? Condensors are usually associated with points ignition systems in my experience.
Their is an ignition pickup on the left hand side of the engine that's triggered by a "nodule" on the flywheel. These can fail, easy way to check is to test the resistance with a multimeter. There are 5 wires exiting the engine on the left, 3 are yellow & are from the charging system, the remaining 2 are the ignition pick-up wires that lead to the CDI ignition box.
