Thanks for your input! I'm by no means an expert, but i enjoy working on my own on the bike. I'm learning by doing. I've fiddled with the pilot screw before, after a mechanic (!) messed it up. And I've been happy with the setting for the better part of a year.

As i've said.. the only mystery was why there was a sudden change in the way the bike behaved. But until I figure stuff out, I couldn't let it run lean and crappy. Especially since Seafoam is not available to me.

As for the oil.. I'm 'by the book' on this one. I ride mostly in the city in heavy traffic. And it gets insanely hot during rush hour. I believe it's better for the bike to have a bit more viscosity under these conditions.
