Actually, no. Have tried everything under the sun and given up. I've just learned to live with it. If I could get any money out of it, I'd sell it for this single reason. I do notice that it correlates to temperature. Rarely happens when the bike is cold. The one thing I've never bothered to check is the fuel pressure regulator, which would be next on my list of things to investigate. I plan to pull the motor and do a thorough tune at some point, so hopefully will catch it then.
