[QUOTE="Bounce, post: 1431442, member: 257"] FJR had low-load surging around 3500 until they changed the transmission and then (IIRC) all things happened at different RPMs than before but I would think that would shift the surging down instead of up. Commuting, stuck behind someone doing 35-40, and cruising along. It's more like the ECU can't pick a map and keeps flipping back an forth between 2 so it surges. The last post about it being there around 3000 RPM seems to hint at this though. Maybe you're talking about something else. [/QUOTE]
