Forgive the plethora of questions, but the Mana is a new to me bike. Today, although starting fine it seemed to cut intermittently to one cylinder as I accelerated away. This went on and off for the first mile or so, riding like a pig, then suddenly ran fine for the rest of my trip, 20 miles or so. After leaving the bike for 10 minutes, I had the same problem again. I thought fouled plug, but I see it runs two per cylinder. The lambda sensor was replaced 1000 miles ago according to the service history. As I've mentioned before, the bike is a 2009, but has only covered 4000 miles from new. Any theories?
