Re: what did you do to your motor bike today?
57, Have you replaced your clutch with a non OE clutch (shoes, arms, or springs)?
Is your clutch cable sticking? When I first built my friction drive bike, I was having a similar problem (no carb adjustments to make, but bike was idling up some). It was the cable causing the problem. I used a gearshift cable instead of brake cable, and used lots of chain oil on the housing, and it quit happening.
