Thanks to all of you for your responses. I am not sure why there is a concern with 10W40 oil. I switched to 10W40 at the 600 mile checkup and followed the recommendations in the owner's manual. I have been using it in my Gold Wing since 2003 with no issues. Older Gold Wings do NOT recommend using synthetic. Note that I think my CB1100 vibes actually increased slightly after the oil change. I did add close to 300 miles this past weekend and the engine is a bit smoother after that ride. I have Grip Puppies and do not feel it in the bars, just the tank and it is not terribly bad - just a minor annoyance.
All in-line 4 cylinder engines have substantial second-order vibration. See my earlier posts for a technical explanation. On the CB1100, Honda has done a decent job quelling them with a balancer shaft and one rubber engine mount. Some other I4's are a lot worse. Still not as smooth as a CBX or Gold Wing. I am a bit spoiled from having a few bikes that were smoother, but I like riding the CB.
