If the headlight went brighter with increasing RPM I would be concerned of an alternator or regulator problem, which may strand you in the middle of nowhere.
This is normal lighting before fuel injection.
The battery would help at idle because the alternator isn't spun up enough @ 600 rpm
With FI, the alternator has to be providing full stable voltage @ a high idle @ 1200 rpm
thanks for the insight guys ... we'll see, I guess.
did a ride on this bike a couple weeks ago, and didn't have any battery charging issues, I don't think.
what i've found so far was definitely a loose ground on the battery.
pretty sure the pre-Gen KLR has an exciter-coil ignition system, and as long as that is functioning to generate a spark, the usual alternator/regulator/dead/boiled battery problems won't strand you like on a streetbike, because the KLR will run without the battery.

the last time my pre-Gen wouldn't start after turning it off for gas in Stonyford, I discovered that the bolt for the battery ground had actually fallen out miles back somewhere and the ground terminal was flapping around in the breeze.

I have a parts bike, so I'll poke around and bring a spare regulator. I may already have one in the saddle bags ... know I carry a spare black box/CDI unit.
I'm sure I've misstated something ... my understanding of motorcycle charging/ignition/lighting systems is dismal ...
