I've heard of the 900 dropping it's spring, allowing the kickstand to flop around a bit. I had to have mine welded solid, re-drilled and fitted with a bushing to keep the spring in place to solve the aforementioned "flop", as the original mounting hole had worn out a bit, and I've seen quite a few people with that issue. Perhaps in your case it slipped without dropping off the stand and is catching on something?
