This morning, I balanced the carbs and took the bike out for about two hours. Cold ride, but exhilarating nonetheless. The engine was transformed with the new carbs. Started immediately, and the choke was very smooth and linear. The engine lost all the chain noises, and was as smooth as it could possibly be. I live in the mountains--going uphill before the rebuild, the engine was struggling at lower RPMs. Now it surges smoothly ahead with a slight flick of the wrist. Downhill, the engine used to pop and backfire. Now it burbles happily and smoothly. On the flats, the engine now has an almost turbine whine--like a huge electric motor making a very pleasant whirring sound, along with the exhaust note. I believe it's the best it can be--the outcome of following your advice, and utilizing your services. I'm very pleased. I do feel sorry for all those souls who never rode a properly running CBX. I was one of them until today. Leon Summers, CA
