[QUOTE="RossKean, post: 1437612, member: 19880"] Playing with it some more. Used the throttle lock to keep it running at around 1200 RPM after initial warmup. It actually stayed pretty steady as long as I let it run (~10 minutes). Responded decently to throttle. Fans came on and cycled normally. As soon as I let off the throttle, it died immediately. Idle speed adjustment didn't really help. I checked and wiggled every electrical connection while it was running and nothing made any difference. I did notice that every couple of minutes, I would get a "stumble" in the idle but that isn't abnormal for an FJR. Start with a TBS with air screws 1 turn out from fully seated as a starting point? I don't really want to tear it apart again unless there is a reasonable chance that these symptoms are caused by a cam timing error. Can't imagine it has anything to do with valve clearances - I couldn't have messed it up that badly. One more question - do you route the throttle cables over or under the coolant pipe? Can't remember what they were on my '07 but they were under the pipe on this one. [/QUOTE]
