bike idles but floods and dies

The stator on a KLR has a separate set of "thing-a-ma-jigs" to generate spark for the engine. You don't even need a battery to run a KLR once it is started. I don't think it is your plug, or your hi-voltage wires, as you bike still ignites a really rich mixture, which is more difficult than a leaned out mixture...right? You are not blowing out the plug either. Could the smoke be oil burning? I don't know much about valves and valve guides, or oil rings (which I hear are not that good on a KLR) could leaky seals or really bad oil ring do that to you at high RPM?

It could be fuel-related, but it could also be a symptom of a fault in the charging system and a discharged batery. Putting a meter on the battery at rest and with the motor running should give you a quick read, and at least rule out electrics if they are not the problem.
