Problem solved! Thanks to everyone, especially Barton. Problem was a totally clogged pilot jet. I decided to replace with a #42 PJ per a friend's experience. While I was at it, I installed a Zip-Ty pilot screw, JD Jetting kit and Boyesen quick shot. Bike runs better than it did from new. I'm wondering if the pilot was already semi-clogged from the long trip oversea? I've heard recommedations of cleaning jets after delivery. Also the main culprit seemed to be the famous green crap. I did run Sta-bil through it at the end of last season, but I don't think I ran it long enough. I've used Sta-bil for years in my sleds, never a problem, but always ran them longer. Anyway, thanks again.
