[QUOTE="Chief, post: 210626, member: 24546"] Georgieboy, As far as which circuit is lean, all I can tell you is I recently experienced the same problem. After running wide open, then going to an idle, the bike would surge up and down for about 15 seconds. This occurred after I went leaner on the pilot. from 52 to 48. After I bumped the pilot richer to a 50, the problem of surging was eliminated. My suggestion is to try richening the pilot until the surging stops. As far as why an engine will surge when lean, I've been wondering about that myself. What you guys are saying about the more comlete burn makes sense to me. Also could it be that having too lean and therefore ,a less dense vapor at the carb reduces the vacuum at that point and allows the engine to rev higher than it normally would? Joe Chief [/QUOTE]
