DR200SE No battery no runny ?
Could someone please start there bike and disconnect the battery and see if it does the same as mine?
The DR200 will idle "ok" when the battery is disconnected but a slight twist of the throttle it will studded and stumble like it's missing. Switching to hi-beam it makes a slight improvement which leads me to believe that the regulator isn't designed to work with out the battery so the ignitor (CDI) doesn't get 12 volts. The voltage dropped to 8 when disconnected.
So my possible solution I will be testing is (given this isn't just an issue with a faulty regulator) I believe a 15v capacitor across the regulator red and black/w wires will solve the issue. What do you think?
