I had the same issue (low idle coming down steep hills). Tried / checked a bunch of different things: needle height, air screw, pilot valve, idle rpm, etc.
Took a while, but finally figured it out to be exactly what you described: clutch drag. Most of the places it was happening, were really steep / technical downhills where you went down as slow as possible. This meant the rear wheel speed was slower than it would have otherwise been at idle. And thus with the clutch dragging, the rpm slowed down.
I've just learned to deal with it. A quick blip of the throttle every 4-5 seconds is plenty to keep it from stalling.
