Hmm... must admit that sounds unlikely to be the cause of the problem at such a low mileage, I should have read your initial post more thoroughly. :o
It does still sound very much like a carb issue though. I wonder whether the springs might have weakened with time? The sliders rising up too fast would then give a reduced airflow over the jet and a leaner mixture. Does anyone know what the free length of the springs should be? It's not a spec listed in my Yamaha manual.
